Oil Spec for Lowest Wear & Deposits

Another internet nutswinger. Good job, Overkill.

Do not feed the troll!

I would agree. The Europeans tend to use different viscosities than North American, Japanese, and Korean vehicles are speced for. An "average" vehicle of one of those pedigrees does not need a high HTHS 5w-40 synthetic for getting groceries or leisurely highway runs, all with short OCIs.


Even my grocery getters are subject to having the yellow water beat out of them occasionally, I'll stick with the better rated ACEA oils...Thank you...

My problem is whether we can trust Mobil since they are famous for failing Sequence IVA in GF-4 synthetics (Mobil1 5w30).



Vavoline(a competetor) says they failed. Mobil and API says they didn't. Buy the way, what are you looking for in an oil? For a Chevy and a Dodge most any 5-30 will work.


I am totally NOT interested in "what will do". Few people on the forums here want minimum performance, or we would just go down to Jiffy Lube and ask the pimpley faced oil changer what he thinks.


Overk1ll stated it very well for you. However during the period of time that Valvo and BP raised questions about M1 5-30 and the Seq 1V test. it was reported by a very trusted BITOGER that attended the 24 Hours of Daytona, that several teams used off the shelf M1 5-30. He had a pit pass and ask why they used this oil. Their answer: "Because it works" and worked well it did. You see, these teams can afford the very best, but this oil is what they chose, and skimping on oil is not a place they cut corners. Also there is no need to belittle quick lube shop employees. I would think most here at BITOG have their oil change at one of these type of places.

As already pointed out, a 0w30 or a 5w30 isn't just automatically a suitable 0w30 or 5w30. GC meets some impressive specs. There certainly are some useful specs that it does not, notably SN/GF-5. There are 0w-30s that do. Again, as already pointed out, the European oils often have a very high HTHS that isn't needed in the North American market.

The spider diagrams should not be viewed as gospel to compare oils. The tests themselves, while more arcane, are certainly more useful. The diagrams themselves have neither scale nor context.

But, a supercharged Marauder is certainly not an Impala, either, or even a run of the mill Town Car. I've had many Chevy small blocks (and later on, some Ford 302s) run into hundreds of thousands of miles (and combined, millions of miles) in fleet use on ordinary, API/ILSAC rated oils.
