How Is Synthetic Oil Different From Regular Oil?

[@Varnaj42]

I bought a new Toyota Tundra in Jan of 05. I'm still driving it. I do my own maintenance. I never have used anything but 100% synthetic oil. In recent years I don't drive much because I'm in my 80s now. I just change the oil each May regardless of mileage. I have never allowed the oil to remain in the engine after it began to turn the dark color. I have the Toyota 4.0 L V6 in a 2wd single cab body. It has never yet failed in any way. In two months it will be twenty years old exactly. The truck still gets the original range of mpg. Between 19 to 24 mpg. I buy my oil usually at Walmart in the five quart bottles for convenience. I will continue doing so. I expect this Toyota to still be running perfectly for my son long after I am history. Good video....

[@bloqk16]

When I first made the switch from conventional to synthetic engine oil some 30 years ago, I did a heat test on small samples of conventional and synthetic. In two open metal containers, I separately heated the oils using a torch flame on the bottom of the containers, comparable to heating the containers on a stove top. The conventional oil produced thick acrid smoke, eventually igniting with a dirty flame, similar to a burning tire. The synthetic oil was heated the same way, where the oil was visibly boiling, but with no smoke; and after a longer period of time than that of the conventional oil, ignited into a smokeless flame comparable to refined kerosene. That made a believer out of me of the heat resistant properties with synthetic oil.

Cooking oil especially palm cooking oil beats the best synthetic oil on heat test. I tested it many times

[@dvader3263]

@@gombalmukiyopujaankuGood luck with that. Palm oil doesn't have the stabilizers, anti-wear additives, corrosion and rust inhibitors, detergents, dispersants, viscosity modifiers, seal swell additives, antioxidants and others which motor oils contain.;-)

My car is designed for synthetic oil, I am not a petroleum engineer, but this car has 145+ thousand mile on it. The manual says to use 5w20 or 5w30 synthetic. With 145K on the car, I am not messing with THAT success. I use the same brand EVERY TIME

[@bretthibbs6083]

I agree my 2000 4.0 is designed for conventional and and that's really the only I ever used in my vehicles since my forst car was a toyota corolla and knock on wood I never had an engine problem and I have used various brands over the years but my main go to oil is valvoline for my jeep.

[@andrelafrenais4478]

Thank you for this very useful information.

[@wooddawg4868]

I have used both types of oil. The main thing at the end of the day is lubrication. As long as the oil is clean you’re basically good hands down. You’re not going to run out a motor doing religiously changing your oil. I had a 2003 Harley Davidson Road King with a 96 cubic inch motor with 105k miles on it. We broke case open to install a gear drive cam and upgrade displacement with new heads, we kept new heads on because their was literally no wear because of my religiously changing of oil.

[@danherrmann8755]

Thanks for information. Explanation made me understand About the difference.

[@Davido50]

My expensive newer Ford F150 & Ranger 4wd trucks have GTDI engines thus benefit greatly from Full Synthetic oils. Used that type oil from 1st - 1000mis. Will continue to do so! Same brand too.

[@georgerhone4106]

Paraffin wax was also used in oil and it caused a lot of sludging when the old 525 castrol oil back in the early nineties was a horrible with paraffin wax

Tribology is the study of lubricants, friction and their relationship. They study the effects that lubrication has on engines from the least expensive power mower engines to locomotive engines costing $750,00 to $1,000,000 and engines beyond that where repairs can get extremely expensive. This video is a very informative perspective on the basics of Tribology! Thank You!

A pitch by Mobil to use synth oil - for obviously advantageous reasons. In Texas summers, synth is always the ea y to go. However, change your oil, twice as often as manufacturers recommendations.

[@algreen4637]

Here's another tip change the filter between oil changes and watch how clean the oil stays. Just the filter ok

[@dannybryant6873]

Thought experiment. What if one bearing in your engine was only getting 10 % of it's normal oil flow. What oil would you want. Regular oil would be quicker to degrade and turn to varnish thus further restricting the flow. Leading to bad things.

[@EdwinMendez-w6j]

Synthetic oil was the greatest invention ever made for engines. Even works well on snowblowers. 😊

[@Funkydood]

Suggestion: Next time, do a deep comparison between Full Synthetic and Semi-Synthetic oils (i.e. the percentage of conventional oil & synthetic oil mixed in a container of Semi-Synthetic oil.)

Can you make a video on speedometers, when did they become common in vehicles and how was the first one calibrated.

[@JimmyTan-h6t]

I need to evaluate first before drawing an anecdotal conclusion. (1) I’ll for extreme friction load capability to simulate the friction pressure in the crankshaft, piston- cylinder, push rods which reaches 120,000 psi ! (2) Do a wear particle count and under microscope, assess the metal particle sizes to see how much debris are in the 10+ micron sizes. Oil is just a carrier fluid which carries with the oil the performance additives. Thus, this competition is comparing the additive in synthetics versus in refined petroleum base oil.

[@totome2206]

I have a MB E350 CDI and use exclusively the 229.52 oil MB approves for my engine, probably only synthetic oil. I have 265000km and no oil consumption.

[@ahoorakia]

While synthetic oil last longer the oil filter will not,so if you decide to go with that make sure at the half of the milage of your oil change change your filter meaning if you want to go with 7000 mile between oil change, make sure you change the filter at 3500 mile once and again at 7000 mile with oil change

[@EllieMaes-Grandad]

Put an oil-cooler in the lube circuit; added protection has benefits.

[@andrewwmacfadyen6958]

An oil cooler can do more damage than good. A lot of engines these days have an oil water heat exchanger this warms up the oil to working temperature after a cold start and then keeps it in the working temperature range which is normally within 10 or 15c of the normal coolant working temperature

[@tjm3900]

NO ! Many additives in modern oils are only activated with heat. Most people in the oil industry agree that 175 f would be a minimum optimal oil temp, modern oils can be quite happy at 300 f while Group IV synthetics can take considerably more.

I have a 2014 Ford Fusion of which I've changed the 0W/20 synthetic every 3-4 K miles. I've been told that it's too frequent and it can run 5-10 K miles between changes. My problem being is that EVERYBODY has a different opinion. I'd seriously appreciate anybody who knows the 4-banger WELL and can SERIOUSLY tell me how often to change my "pricey" oil with NO generalities. P.S. I live in SC where it does get hot in the summer, (obviously), and I drive the car 30 minutes to and from work, a TOTAL of 5-6 days a week and that's about it. Your thoughts?

[@RobertEndl-pl9kr]

Very helpful but only in a general sort of way. What is really in synthetic oil? What is a paraffin and why does it matter? What is PAO and esters?

[@bretthibbs6083]

The second question is that paraffin is a wax and Pennzoil is well known for using it and it causes a lot of sludge build up in engines and i have seen first hand what it can do and it's horrible. A mechanic at a dealership that i worked at had to use a vacuum cleaner to clean all the sludge build up and it took him a long time to clean it by hand and the half of the engine had to be torn down in order to clean it.

[@tjm3900]

Don't ask difficult questions, he is trying to keep things simple. Oil groups, POA's, synthetic blends etc. can be in part 2

Many modern automobiles are designed for specific oil. Our new 2025 RAV4 requires 0w16 synthetic. The engine is designed for it. Those who say that it's too thin simply don't know the engineering behind why it is required.

[@andrewwmacfadyen6958]

Some amount of myths floating around in the comments. Truth is even a cheap supermarket synthetic will last longer without breaking down than any mineral oil. Synthetic oil is also much less dependent on additives to achieve the desired viscosity and detergent characteristics. Additives start to break down after the engine reaches running temperature. All oils are likely to have some synthetic and some mineral oil in the blend but so called sem-synthetics were originally a substitute when synthetic oils base stocks were in short supply expensive. On a historical note mineral oil base stock made from undersea oil fields base stock (ie Gulf of Mexico or North Sea) were always considered the best for lube oil. If you have a turbo engine always use the best quality fully synthetic

[@aonforme3349]

Good stuff!!!

[@cyclenut]

In 79 three people gave me a old VW beetle, 63, 64, 65. Each owner use different oil. One used quaker state.and the bottom of the crank case was thick sludge. The other two were clean. Back in the 60s all oil was oil. So some regular oil is good for old cars.

[@bloqk16]

A legend going around back in the 1960s through the '70s was that Quaker State and Pennzoil, both being from Pennsylvania crude petroleum, was paraffin based oil, and was more prone to having a waxy sludge buildup than engine oils from other regions. The same legend had it that if proper maintenance intervals for oil changes were done, no problems. But, if the oil was subjected to abuse of an overheated engine, or, prolong mileage between oil changes, it could result with a waxy sludge buildup with Pennzoil and Quaker State.

[@Custom-Sound-DJ]

You missed one very important thing. Most newer vehicles require full synthetic. Especially Toyota hybrids you also must use the correct weight which is typically 0w20 or 0w16 and some really new ones require full synthetic. Also, conventional oil is not made in that weight ow20 ow16 ow8.

[@diaskent829]

I drive a 2008 Suzuki grand Vitara. Which oil would you recommend?

[@SteveWarlee]

So the red double decker london bus company decided to stop changing their oil but only the filter more often and top up with regular Oil as needed. Great success. If you dont rev your vehicle like your a F1 driver in an uno, and chilax at 80 kph even on the highway, you can do 30-000 kms and the oil will still be be golden coloured. Ive travelled africa big time in my 2003 nissan cabstar, and havnt had to top up my radiator since new. Oil does not lose its viscosity and the sludge can be avoided by placing a magnet on the oil drain cap collecting metal fines. The impurity thing is a load of crap.

[@RedDwarf-r4x]

Oils ain't oils claim the Castrol adds. Castrol make a good point and very good motor oils. However, in some cases you should use a conventional oils with no additives. Motorcycles with a wet clutch are an example. I had been using a top brand oil with a anti friction additive on my Honda motorcycle, thinking it would prolong the engine life. After some 40,000 miles the clutch started slipping. Turns out the anti friction additive was causing the clutch to slip. Clutches need some friction to operate well. I learned my lesson and now use the recommended Honda oil for my motorcycle which does not contain additives.

I sure wish my local PX stocked diesel specific oils. This is Belgium. 27 euro a liter is criminal. 5 quarts of gasoline castrol at the base is 27 Euro. I need 7 quarts or 6.5 liters. Those diesel detergents and additives are important for a long-term owner. I can't afford a new e-class Mercedes, but I can afford to keep my S212 2011 in top condition. The new one is bathed in technology, but the ride is the same. Honestly, the technology was distracting.

sludge is the result of metal wearing between cylinder wall and piston ring. It is not the product of the choice of oil. Synthetic oil tends to become gummy and sticky that hinders the performance of the engine.

Yes perfectly fine. As long as you drive it for more than 30 mins every week. Thats to eliminate the moisture collection that can cause rust and corrosion. Heck, you can even do 2 years with synthetic, but just to be safe do it at least once or twice a year. Remember oil changes are cheap, engine rebuild/replacement is not

[@FirsthomeDIYGUY]

NEVER drive 10k miles between oil changes 😳

[@Cst10idk]

what is the different between motocycle oil and automotive oil? Why wet clutch motocycle oil last too short?

[@doodskie999]

Not much really, just the additives. Heck you can even use car oil on a motorcycle or motorcycle oil in your car vice versa and 99% of the time it will be fine. But motorcycle oil has some additives to allow lubrication but also allow the clutch to grip properly while car oil has superior anti wear properties. Motorcycle oils last shorter due to the high rpm nature of their engine. Though some new bikes today have higher service intervals between 7000-10000kms like KTM and BMW. I actually experienced puncturing my bmw 1200gs oil pan, fixed it with jb weld and topped its oil with diesel oil as it was the only oil available in the middle of nowhere. I made it home, changed back to motorcycle oil and my motorcycle was fine lol
