Mobil 1

They have some info on the Seq. IIIE test.

Q. HAVE WE COMPARED THE RESULTS OF 200,000 MILE ENGINE TESTING OF MOBIL WITH A CONVENTIONAL MINERAL OIL ?

A. We have completed a 200,000 mile test on a premium brand of a 5W-30 mineral oil in a 2.3 liter engine similar to the Mobil 1 test, using 15,000 mile oil drains. Highlights of the results include:

- Engine wear rates were lower for Mobil 1.

- The mineral oil produced heavy varnish deposits, while Mobil 1 was virtually clean.

- The mineral oil consumption was eight times higher than Mobil 1, which can adversely affect emission systems. The original catalyst functioned for the entire 200,000 mile test for the Mobil 1 lubricated test car, but had to be replaced at 130,000 miles for the car tested with premium mineral oil.

- Fairly rapid degradation of the mineral oil was indicated during the test with viscosities increasing into the SAE 15W-40 range. This obviously would adversely affect any fuel economy performance benefits. Mobil 1 remained at the SAE 30 viscosity level throughout most of the test.

Good grief, what kind of test is this? They ran a conventional 5w30 using 15,000 mile OCIs for 200,000 miles. Did they think they were going to get good results? I'm surprised the engine even made it 200,000 miles. Wonder what the results would have looked like if they had used a more reasonable 5000 OCI?

All this test showed is you can treat your engine like crap, use plain oil, triple the normal OCI, and still go 200,000 miles.

Usually these type tests use 3k oil change intervals for the non synthetic and extended OCI for the synthetic. The person who wrote that probably didn't understand the test and wrote it up wrong to give the impression that the test was 15k intervals for the dino. Not having the test to look at I wouldn't take this for too much value.

I haven't seen any 5W30 dino turning to a 15W40 in our UOA section with 3000 miles oil change interval

I think most 5w30 dinos turn into 10w20 oil before the 3k mark actually.

Patman they will thin cause losing its VI's (shearing), it will thicken due to being over heated(low flash point)

Yes, eventually they will thicken up, but on here we've rarely seen that, because I think you'd need to keep the dino oil in for quite a number of miles before this would occur, and most dino UOAs on here are around 2000 to 5000 miles.

Where did you see that? I couldn't find that in any recent UOA's posted.

A lot of the dino oil 5w30 UOAs posted on here show themselves as finishing up as 20wt oil.

G-ManII, GM's lovely new oil change algorithyms do not care if you have 5W30 Walmart DIno or Series 3000 5W30 Amsoil in your sump! Some vechiles have a maxium of 17,500 mile OCI based on your driveing conditions. With that said 15,000 mile OCI is pertanent.

Someone recently posted about consumption issues in the smaller Toyota truck (I believe) and how he'd would be using synthetics if he knew then what he knows now. His story parallels this Mobil test. Granted 15K is too long of an OCI for dino...but...maybe not with Honda telling owners to change the oil at 10K and filters at 20K. Go figure.

Using synth is truly a win-win proposition in long term cases.

I have searched the UOA section and I can't find a single dino 5W-30 that thinned to a 20 before the 3K mark.
I'm not trying to be ugly, but I just haven't seen the data to confirm your statement. I may have missed one or two, but that is a long shot from "most 5W-30 dinos".

Here is two that went to a 20wt before 3k .
