Synthetic vs Conventional Oil - There's A Good Reason To Switch


Synthetic vs Conventional Motor Oil - Why Is Synthetic Better For Your Car?
Sponsored by Mobil 1 motor oil. Learn more about Mobil 1 full synthetic motor oil:
What’s the difference between synthetic and conventional motor oil? There are many advantages of synthetic motor oils, and in this video we’ll be focusing on four key areas. First, we’ll talk about viscosity index, and why synthetics tend to have less change in viscosity with temperature change. Second, we’ll examine volatility, and how synthetic’s more uniform molecular structure helps prevent burning off oil in your engine. Third, we’ll look at how a motor oil made with synthetic base oils impacts the use of viscosity modifiers, which can cause deposit formation within your engine. Finally, we’ll discuss oxidation, which ultimately is a cause of sludge and leading factor necessitating oil changes, as oxygen reacts with motor oil and causes it to thicken with time. I spent time discussing all of these topics and more with Mobil 1 engineers. Watch for all the details! #Mobil1Partner

    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?

    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.

    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.

    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?

    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.

    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.

    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.

    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.

    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.

    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.

    @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.

    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?
