I'm glad you explained this. I didn't know the difference between synthetic and conventional, now I know! THANK YOU!

I guess my confusion is about why everyone is not using Synthetic oil if its a superior product? I bought a diesel water pump that specifies a mineral oil at 20W-40... It made me ponder why they would exclude synthetic oil with a similar SAE?

If I change from conventional oil to synthetic oil should I use the same viscosity weight? My boat requires 14-40 weight oil.

Inciteful is probably the wrong word to use at this particular time.

so what I'm hearing in a dumbified explanation, is that synthetic oil is better than conventional oil because it has fewer impurities, lasts longer, and provides better protection on the engine

Remember, the only way to find out how good a oil is, is to test a sample at regular intervals. Ole grand pappy's smell test is not reliable. Most companies formulate down to a price point making their product meet the minimum standard. Ever wondered why synthetic oil can cost 4 dollars per quart up to 12 dollars per quart? Same deal with paint. You get what you pay for. BTW this channel is awesome.

Is using Ceretec by liqui moly safe in the long run? What are the cons using these friction modifiers? Thank you in advance!

How does this apply to transmission oil?

I went EV in 2014 and haven't bought any motor oil since. I am convince that synthetic oil is better, but it is unlikely that a car buyer will ever see the different or benefit from synthetic oils. in 94 I bought a new car and started with full synthetic. At 50k mi it got t-boned and maybe should have been totaled. No one care what oil you use in an insurance claim. I then started using the cheapest oil I could find that met the manufacturer's requirements. I picked up a shitton of oil for just $.40/qt. I had been changing the oil at 5k mi intervals since new, but at 180k mi I switched to 10k mi change intervals. At 260k mi and 12 years the engine was still running great and was the most solid part of the entire car. Someone rear-ended it making it impossible to open the back. It was totaled this time, but still running fine. It is rare to find any car lasting longer than 1/4 million miles, but it can be done without paying for synthetics. BTW the car was a cheap Ford 4cyl, less than $10k new and never needed any engine work. Even at the end, the old consumption never exceeded a qt in 10k mi, and I'm sure there were some leaks by then.

Refilling Mobile 1 almost stopp the oil consumption on my service van cars.

what do u thing happens if you mix two different weight oils , as in a 5w-20 and a 5w-30 ?

I have always used "conventional" oils in my cars and trucks. I have never had an engine failure, with the exception of my wife overheating a Jeep. The water pump had failed and she kept driving. This makes me wonder, if I change my oil at reasonable intervals and never let the oil run low, how important is synthetic oil for me?

So don't run a turbo (heat) and keep your drain intervals short (10,000km) and Dino oil should suffice.

I have a 2019 ranger in Canada. Manual calls for Ford's regular oil. Strangely, US manual calls for semi synthetic. I'm thinking I should switch to synthetic? 2.3 litre turbo. Dealer asked what oil I wanted. Opinions please?

Dobra práce !

Perfect! great Video!

Hey man can you do a video on ABS vs no ABS? Like stopping ability/distance etc...

Well I just put synthetic oil in my car today so I guess I made the right choice!

If you don't live in an area where the temperatures hit sub-zero in the winter months, then you probably don't actually 'NEED' synthetic oils (but synthetics do help prevent 'sludging' in Toyota V6 engines). If you live in a place where it does get really cold in the winter, then you probably should switch to a full-synthetic engine oil as it won't thicken up to a hard paste at -40 degrees.

Mobile 1 is not a synthetic. Amsoil or Redline are true synthetics. A simple google search and anyone can find out what is considered real and what is not. Mobile 1 is still based on a traditional oil.

Welcome to NOlocals.. *RetroPost* for views.

How old is this guy jw ??

5W20 full synthetic is the best gun oil ever.

I can't help but think of the interview with the laboratory technician (possibly lab owner) who has been interviewed several times and asked his opinion based on the results of thousands of oil analysis reports whether he thinks synthetic is worth the cost. His answer is no. He states that the benefits of synthetic oils is mainly displayed in extreme cold temperatures where synthetic flows better than mineral oils but for everyday "lower 48" locations it simply doesn't show a wear benefit. The lab tests don't care what brand or composition the lubricant is. The equipment simply returns a test result.

TRULY A VERY EXCELLENT VIDEO!!!! MERRY CHRISTMAS!!!

Been watching your channel since you started! Love your stuff!!

Hello can u suggest good engine oils with grades explained b4 , c2,c3 etc for my Hyundai elite i20,1.4l crdi . Owners manual suggests c2/c3 or b4 , or below if not available in the country . Which grades should I check for in the oil bottles and what does they mean for my diesel engine

this was really good

"Hopefully this has been insightful...." I don't think you have released a video that has not been insightful!!

How does a synthetic blend engine oil compare and how good is it?? @Engineering Explained

Jason how about a video on the base stock that is used in synthetic oils. For instance, the oil I use on my wife's Prius is Pennzoil synthetic which comes from distiiling natural gas. Other synthetic oils use petroleum oils and are refined. Amzoil use a base stock that is supposed to be very stable. Please explain.

What if I'm putting a fresh quart in every week?...synthetic gets spendy and it cuts into my beer money.

So now tell us about motor oil in the yellow jug that says '"Made from natural gas". How, why and features if any.

Great content and information, even though you are so annoying. Thanks!

The liquid Pistons X- Engine doesn’t need oil and has 70% efficiency.

Mobil 1 paid me for this vid. Guess what oil is best?

Conventional at AutoZone: 29.99 Mobil 1 at walmart/amazon: 27.99 Anyone saying price is thier reason for not switching yet they buy oil at the autoparts store is retarded. Also get your filter at the dealership its not much more expensive and if you call the dealer for the part number you can find it on Amazon for the same price as the shitty stp filters you've been buying at autozone

Get a pack of cheap-o magnets and stick a few on EVERY oil filter you own - - Now those fine metal shards less than 0.00025 that pass thru your filter will now STAY in your filter !!

Can you do a comparison with transmission oil API GL4/GL4+/GL5 and mineral/conventional oil?

Was really hopeful this video was going to mention zink, and diffrent types of camshafts...

It's kinda uncomfortable to hear your voice ,may be that's because of the way of speaking

I use Motul full synthetic oil in my Bajaj Avenger 220 street.

Great info. Super cool way to explain something that a lot of people even when you explain something such as oil weight don’t get. Awesome way to get really important information to the non mechanically minded.

Im still watching your videos uploaded 6-7 years back and your appearance is changed now :(

Nice history show :P What about oils in electric motors and their driveline? =)

I'm running out to my cars right now and I'm changing over to synthetic or the cheaper conventional synthetic blend since my cars only used to use conventional Really enjoy watching your videos always learning something new everyday

My synthetic hasn't been changed in 200k miles... I figure I've already saved $300.

I have heard that some crankcase seals and other rubber part on older cars does not like fully synthetic oils. Can you elaborate on that please?

Yessir Mr. Russia- as your cars gets older, all the seals and gaskets shrinks, contract, and rot from wear and age, and when you use synthetic oil because of its lubricious properties you will experience increased leaking everywhere.

Naw, Those were the ester base synthetics from 30 + years ago that swelled the seals too much causing issues. The modern formulas of the top premium real synthetics use combinations of PAO with some ester and other stuff to keep the seals pliable. The group III highly refined hydrocracked petroleum based synthetics are formulated to be nice to seals as well I believe. This is basically said, but there is much more tech to it. But so it really is a non-issue today.

The up front cost of the oil is higher, but it will hopefully dodge a much bigger bill down the road.

I know Mobile1 is popular four stroke oil, just wondering what your take is on some of the popular two cycle oils are, like Blue Marble , Amsoil , Royal Purple, Legends and Klotz. a few have been around a long time but you don't hear much about them. could be advertising cost....

what about shear and mechanical degradation of oil long chain viscosity improvers are especially susceptible to this and the fact that synthetic uses less of them is a good thing

I'll wait for my turbo to go synthetic

Jason, I am confused. Under the "Volatility" section, you said that when oil gets heated it burns off: " . . . synthetics slow this effect, because not as much will be burning off". In the Oxidation section, you say that oxygen combines with the oil to form deposits. But, I think, "burning" is defined as an exothermic reaction when oxygen combines with a fuel. So, is the motor oil burning in the Volatility section? If so, would that not be Oxidation (combining with oxygen)? Please help.

KevinK2

29 dager siden

The first section is about evaporation of the lighter "ends" of the oil due to heat, resulting in thickening of the oil. The Oxidation is a reaction between oil and O2, and creating sludge. In both cases, some "lighter ends" of the oil vapor is burned in the combustion chamber. The burning is through the engine combustion process, through the pcv system.

I need your email. I have issues to discuss

Can you shed some light on the difference when someone uses turbo oil in a turbocharged engine? But what benefits is the use of Lucas Pure Synthetic Oil Stabilizer.

Hey handsome

@4:31 What about toxicity? Aren't synthetics much more toxic to living beings and the environment? What about production (fossil based) and disposal of the oils? It's a damn shame Jason you didn't talk about this whatsoever.

i have had 3 chevy express vans over the years. Have used synthetic every with oil change every 8000km. I have had engines last 500000 to 650 000 kms life.well worth the expense

Ugh thanks for reminding me I need to do an oil change. M1 & filter sitting and waiting

TLDW??? someone help me out

My proudest accomplishments in engineering include extensive controlled tribological experiements in world class third party engine labs. The difference is dramatic. When comparing nearly every single measurable characteristic of oil and oil durability, there are three brands that stick out: Amsoil, Mobil, Pennzoil. Its a race for 2nd place, by the way. Amsoil is leaps and bounds ahead of everybody else, because they develop their own additive packages. Mobil does not. My confidentiality agreement has lapsed and my life is ruined, so I do have the liberty of being honest.

Does Synthetic Pennzoil actually have a “Base Oil” since it’s made from natural gas? Asking for a friend. 😁

@Jeffrey C its more pure than regular synthetic base 3 oil. And normal base 3 oil use used motor oil(the black oil that u give to Walmart,ecc). The grup 3+ use pure new petroleum oil that is transformed into gas and again in oil.

Group 1,2,3 and 3+(Pennzoil ultra plat) base oil is made from petroleum. Group 4 and 5 base oil are really synthetics.

Mobil1 is definitely worth the extra few dollars every 5-10k miles.

Hog wash. Oil is oil.

Was there any discussion about car manufacturers' approvals? Mobil1 has Ford and GM approvals, previously had Chrysler.

Crazy, I worked at the plant where this stuff is made and I never really understood the advantages. Heard a lot about GF6 though

I replaced conventional motor oil with Mobil I Synthetic Motor Oil in my 1960 Buick Electra with 22,000 original miles. It runs perfectly with no problems!

Great info, I asked myself halfway through, wait - why am I watching this? I don't use oil anymore....full EV, electric everything now haha.

With a flat tappet cam you need to have semi to get enough zddp unless you use race oil

use Motorkote best shti ive ever used not cheap and Evans waterless coolant is magic ( you need to use the pre-treatment first to remove any left over water/based fluid in the system)

I been using Mobil 1 annual protection for about 3 years with no problems on a 04 Gran Prix GT, I now have a Lincoln MKZ with a 3.0T AWD. Would it be a good idea to use it in this car? I'm thinking not so much, and to the least change it early if you do use it! What you think? Auto stores don't like Mobile's Annual oil either! They dont even order it!😅

I only use synthetic engine oil on all of my cars. Two of them have 90k miles and when you open the oil caps, the engines have no sludge, not even discoloration, and seem to be almost new.

what kind of a third world country do you have to be in to even ever consider non fully synthetic lol

What is the Shelf Life for these synth oils such as Mobil 1? Meaning, if I kept the bottle unopened and sitting in my garage at a stable (room?) temperature, how many years can it sit and still be useful in a regular ICE car's oil change?

who tf uses conventional? i got my first car at 17 and i never touched conventional oil, its literally $10 more for full synthetic for 5 quarts

Synthetic is better oil just use it 🤦‍♂️ now in old stuff I recommend a semi synthetic or conventional there’s my 2 cents

the escape I drive uses a synthetic blend....is this the best of both worlds?

I thought I was having a nightmare and back in my Organic Chemistry class.

That's not so far from the reality of some people as you might guess. The grandfather of a guy I know used to drain his engine oil every evening during the colder times of winter, keep it in the house overnight, and put it back in the engine in the morning before driving off to work! For an idea on the time period, I think it was back in the 1940s and 50s.

Mobil One user since the 70's and Smokey Yunick tests :)

Use the oil that is designed for your engine. There is no need to discuss anything other than that.

why don't we compromise here and use semi synthetic....

No, there are processes to create oil from other sources : Ester oils. The process you are refering to is the polyalkylenes (synthetics from petrochemical refinement). Wikipedia will help you a lot on the page "Synthetic oil" if you want to look it up a bit further (and much better than in that video)

Would using 5W-50 synthetic oil better than 20W-50 conventional in hot summer condition?

Amsoil is arguably the best, if you want to pay their price

I would really like to see a video about synthetic fuel. Efficiency vs. hydrogen etc. would be very interesting.

The only disadvantage of synthetic oil is the price..but you do less oil change, I guess it evens out..sorta.

Anyone know why my Cummins would consume (either burns or spits it out the blow by tube) synthetic 5w40 at a rate of almost exactly 2x conventional 15w40? I get oil analysis done every 3-5000 miles and at 7500 miles the 15W40 conventional still looks basically brand new

Do you quit your job as an engineer, to be a full time youtuber? You have great and interesting content, I will be able to learn a lot. 👌🏻

A Chevron Oil engineer told me that there are many advantages to using synthetic oils, but extended change intervals is not one of them He bases this on contamination.

If you read the label on the oil bottles most run of the mill synthetics won't say anything about extending drain intervals. So it shouldn't be done. If anything is said it is only to use OEM manufacturers recommendations. The ones that do say something about extended change intervals are the more premium ones and cost more.

dennis rantanen

27 dager siden

@Dave B Right, but I stand by what I said. Premium synthetics can be run longer, the key word here is premium it's been tested and retested and tested some more, with no detrimental effects. Premiums have stronger, "read expensive", more robust additives that will last longer. You ever heard of oil analysis? That would be the proper way to really gauge how long to go. Of course most people wouldn't bother, that and they won't spring for the expensive premium synthetics, so they go to the costco's, walrus marts etc and get their three dollar a qt. so called synthetic, then run it way to long and hurt the engine and so the dufus grease monkey down the street cries about how bad synthetics are. Now, I am guilty as charged to, I don't do oil analysis either and probably should because I use premium synthetics & being a life long mechanic by trade I should know better and have run way to long. But when you do run long most engines will consume & volatise some oil so you have to check your oil levels, so toping off the oil with fresh helps renew the additives some. The cheap three dollar a qt group III highly refined hydrocracked petroleum based so called synthetics in this country, no. You have to go by manufacturers recommendations.

@dennis rantanen all modern oils have Ph neutralizes in them to combat acidification from combustion by products, but get used up as the burning fuel produces acids continually. Microscopic particles from wear, and entrained air lowering film strength are contaminants that can't be filtered and limit oil useful life no matter how well the oil was made.

He bases it on $ & ¢ . They want to sell you more oil more often. That and they won't or can't formulate for longer drains and they don't have good enough filters.

I have an Honda Civic Si 2017. (Turbocharged engine) I live in Puerto Rico (Caribbean Island) The temps never go below 68f in my city. But when the day heats it gets 92 to 101 degrees F. The recommended oil is 0w20 Can I upgrade to 0w30 or 5w30 ? for better protection? Would it affect in Startups? Thank you. Bernard Ponce, Puerto Rico

Seriously, you don't have your own school? Your information is so fluent and actually fun to listen too! A+

There's a good reason to NOT switch. A rotary engine.

Great Video. I understand the advantage of synthetic oil, but would the viscosity curve for a 5W20 conventional be the same as synthetic? The numbers do refer to cold and hot viscosity measurements.

Are these synthetics any less polluting?
