My manufacture recommends 10,000 miles which to me is ridiculously far to many miles between oil change intervals. I change my oil every 5000 to 6000 miles with “full synthetic”. Ford recommends changing the transmission fluid every 100,000 miles. That’s absurd. I change it twice a year so basically every 10,000 miles. It’s 40 bucks and takes 10 minutes.

Would be nice to have a simple table at the end of the video, summarizing the test results in terms of percentages. For example, the bearing material loss was 300% worse with standard than synthetic. Preferably, each test should be repeated, to make sure the results are not just "randomly" going in favor of synthetic. 🙂

Viscosity (flow) should be the same for the same grade oil, regardless of conventional or synthetic. Synthetic should retain that viscosity and lubricity longer under operating conditions (heat and combustion) than conventional.

[@jasonhooey5677]

Yea but that's not how it goes always. Yes it will remain stable in long oil change intervals but always flows more in colder temps than conventional

I used synthetic for the first time recently. I checked the dipstick after 3,000 miles expecting to see a brown color like I would with worn conventional oil. Nope. The synthetic went from clear to pale yellow after 3,000 miles of driving. It looks kind of like a brand new conventional oil. Very impressed. When that oil gets brown and black it has very little viscosity, feels more like milk than oil. This is why I will never use conventional oil again, it just wears down too fast.

[@plutosforest]

Btw this was STP full synthetic, $22 from Autozone, I paid $28 and got an STP 10,000 mile filter with it.

[@modified93tc]

Oil color is due to many factors. The additive package in new oil gives you lighter and darker oil. The color after running it several thousand miles has more to do with your filter and the state of your engine not the oil initially added. Try using different filters and see how it goes.

One of the most valuable things my dad ever taught me growing up is how to do all my own maintenance on any car I owned.

I have no record of any repairs, service records or maintenance that's been done, but I always replace all the fluids, belts and houses immediately anyway. My question is, which type of oil (semi-synthic, full synth, or conventional) would be best to use when I do an oil change with these conditions in mind; it's a 2004 EFI motor, it got just over 133k miles on it, I live in a south central Arizona where the average outdoor temp stays over 105° (with highs commonly reaching +115°) 6 months outta the year, and it will only be driven less than 10 miles a week and be stationary most of the time. I've never owned a car that was idle 95% of the time, and I don't know what the most appropriate type of oil would be best considering it will sit idle in extremely high ambient temps for 5-7 months a year...

Good for Tropical regions condition, Where as, the 0w30 and 5w30 both are (FULLY SYNTHETIC). Reason people use in new gen Diesel engine and Petrol engine is that, at the time of starting a car, the synthetic Engine Oil as it is very much close to free flowing, the oil quickly gets into the piston areas and then make the Engine start without much hassle or noice coming. Ina way synthetic Engine Oil is also used for high performance cars, the reason is as I said, to get the Oil Quickly To Pistons.

If you DIY, there is no reason to not use full syn. The time spent doing it and the longer OCI completely justify the use of full syn, even in warm climate. These days the price difference in oil is only about 30%. Use Supertech or Costco full syn. If you have a shop do it for you, then the choice is not as obvious. This is because low price oil change is always conventional. A shop will gouge you for full syn oil change. This is because they know you care enough to use full syn and is not as price sensitive.

My standard oil change interval with dino oil is 2500 miles. I drive all in-town and short trips and that's what I do with my car. No has ever damaged an engine because they changed the oil too soon, if the correct products were used and the filter was installed correctly.

Hi, can you do a synthetic vs synthetic + militec. I really would like to know if this metal conditioners are something to spend money on.

[@OYATca]

Simply use lighter oil in winter, thicker in summer. Synthetic in winter, conventional in summer?

[@peteg4328]

The test you performed won’t see much difference because they are required to meet specific specs on viscosity and operating temp. Both will do the job just fine. The difference is longevity/durability, synthetic oil will offer the same protection longer while conventional will start breaking down sooner. If you change you oil often say every 3-5k miles max, conventional likely will be fine. If you are lazy, don’t like changing oil often, synthetic may last longer say10k miles or more.

[@tjlee9901]

sounds to me like it might be better to use conventional if you change it more often , like 3-5k intervals , instead of using syn and leaving it in for 10 k miles . kinda makes sense to flush your engine with cheaper oil once in awhile , even if you have to use synthetic .

[@ericdulyon4601]

Yeah this is all good and stuff. But let me tell you something how many people you know with full synthetic oil that have a car over 350,000 to 500,000 miles? I'm 50 years old and I've seen Toyota's hit a half a million miles on conventional motor oil. I've had nothing but conventional motor oil in my cars. I've had 2 Toyota Corollas that went over 330,000 miles on with conventional motor oil changing the oil every 5000 miles. And you can eat off of the top of the engine of my '06 it's so clean. I got a friend I'm working with that has 420,000 miles on a Toyota Tacoma with conventional motor oil. Growing up I had a friend that his dad put over 400,000 miles on his 1985 Toyota Corolla. I had a 1997 Civic that went over 350,000 miles with conventional motor oil and I sold it sounding like the engine was built the day before when I sold it. You might get a few more miles out of synthetic oils but it's not going to be much more. Who's going to keep their car over 400,000 miles anyway because the rest of the car breaks down.

[@thepseudomasterchef7238]

Any modern full synthetic oil offers more than enough protection...Stuff like Amsoil is overkill unless you are going to setup a bypass and run it 15k miles but I wouldn't do it... Especially in a DI engine Because the fuel dilution would be really bad by 7500 miles most likely...I use castrol Syntec 0w40 euro formula and I get it for like 23$ a jug...77k miles on an engine pushing almost double the stock hp with no issues...so far

[@eugeneabreut5208]

Yea brand does not matter. I bet you most of those oil are the exact same oil poured into different bottles in the same factories. As long as it’s the right numbers and you change it regularly, you will never ever ever notice any difference if you were to use let’s say super tech vs moble 1

My old Ram (2001) 2500 5.9 Gas V8, has been using Walmart 10w-30 high milage full synthetic oil for the last two oil services (5k each w/Mobil 1 oil filter). The oil consumption dropped significantly from 1200 miles per quart to 1700 miles per quart over the 10k test. Overall fuel economy improved by .3 mile over the same period. No oil leakage noted before or after the test. A great value for a synthetic oil; only the Costco and Amazon basics synthetic oils are less expensive. Will continue to this oil in my truck.

[@orfeas92]

Very nice video! Is it possible to compare 4-5 big brands for moto oil 5w-40(eni, motul, castrol and two usa companies)? In Europe this grade is very popular and it is also used in a lot of smaller bikes(scooters etc). A lot of motorists are searching for video like this. Thank you!

Doesn't matter what vessel you use to weigh anything. Use a tare factor.

[@lonniebeal6032]

The anti-wear package and detergent package added to each oil. For the few dollars difference anyone not using full synthetic doesn't value their car. Price difference is a meal at a fast food joint...Not to mention if your engine is clean you can easily do 8000 miles on full synthetic with a quality filter, but not conventional. Do a test of the same brand oil in a 5w20 vs 10w30, heat them up, and bearing test. We already know the 5w20 would win cold pour.

[@basshnter1997]

My 07 Corolla has 206,000 miles using supertech conventional. Uses no oil between 5000 mile ( sometimes longer) changes. And, I value this car because I depend on it to get to work. Of course synthetic is better but most people will never keep a car long enough to reap its benefits.

[@lonniebeal6032]

@@basshnter1997 So you can't spend what, $2 more for full synthetic? Unmentioned benefits are if you blow an intake manifold gasket and dump 2 gals of coolant into the oil you won't ruin your motor. I know, it happened to me and it didn't ruin the motor. Another guy I know who was using Mobile 1 got a lot of water in his gas at a fill up, it ended up with the oil and full synthetics saved his motor. If you depend on that car so much, $2 for that ST full synthetic won't be missed.

Nate, the base oil this synthetic is called hydro cracked Group 3. It just the same as conventional oil with just another extra refinement step. Most likely these are not a true synthetic...as PAO'S and Polyol esters are...heck even the Pennzoil platinum from natural gas will do better...Amsoil and Redline are better if for no other reason than they both use a large percentage of POE base stocks...which has the highest film strength of any base oil and the highest temperature resistance...it is also the best at being naturally detergent without any additives for detergency...
