during a fifteen minute race our oil temps would get up to 300+ if using any non synthetic oils
Mobil one dropped the oil temps by about twenty degrees to 280 and switching to amsoil we dropped it to about 250-260 .......this is not representative of everyday usage but keep in mind that the water temp stays always inbetween 180-200 at all times no matter which oil.....so all in all it is kind of an accepted opinion that Mobil 1 is the cheapest and least effective of the synthetics but all of the higher end oils.......Amsoil, Royal Purple, etc. work better under extreme conditions. I guess it all depends on what your uses are. I just have my own opinions formed because of the info stated above.

Yup i'm just saying after reading about oil analysis results (what's left in the oil after its drained) you learn there is more to take into consideration.

I became really interested in oils and their suitability about a year ago when I had to chose an oil for my new engine, and researched it alot. It was pretty interesting, and complicated. I did a lot of internet research, and I also found a tribologist (friction-wear-lubrication engineer -- spouse of a co-worker) to talk to and asked her some questions about oil and lubrication)
Oils vary from one manufacturer to another, so one company's 0-30 can be a lot different than another company's 0-30 even though both are labeled the same: they may be rated against different standards, or just tested slightly different, and still meet the appropriate standard for that definition, like 0-30
But thickness varies with temperature which is, off course, the whole point of the dual rating 0-30. the first number is the cold rating and the last a higher temp rating -- I forget what now but the data was out there, I dug down in various websites for Mobile, Pennzoil and Castrol and elsewhere , and can go enough data to plot SAE viscousity-versus-oil-temperature-curves for most of the popular auto oils (Mobil1, etc.) from 0 to 255 deg F. The data was buried in the technical spec sheets attached to their web sites, always in a different format, etc., but the same values to the same SAE standard definitions. The curves show how each particular oil varies in viscosity --basically thickness-- from cold to very hot.
One thing I did discover, is that within nearly any manufacturer's product line, a 10-40, for example, will be thicker at ALL temperatures, than a 0-40: In my ignorance, I expected that the "10" would be thicker at cold temps than the 0-40, but the same thickness at high temps since both have the 40 rating. But plotting the curves for all grades of the same type of Mobil1, for example, or various Pennzoil syn oils, shows that is not quite the case: a 10-30 was much thicker at low temps than a 0-30, but still slightly thicker at high temps.
Looking at the various grades and the curves available, and knowing that my vette, like all LS strokers, is hard on oil temp, I picked a Mobil1 0-40 European syn for winter spring and fall (Note, they recently changed the labeling on this oil to delete the "European" and it did not meet certain SAE codes, but I selected it anyway - it was the factory oil in Porsche turbos so I felt it would probably be okay). Although a 0-40, its thinner at low temps than most "5 - XXs" and all other "0-40s" I could find but according to the curves its noticeably thicker at high temps than any other 0-40 and some 10-40s I could find."
What I learned is not to trust the ratings and to dig down to the spec sheets, and that the good oil suppliers provide that data on their web sites.
By the way it is a suberb oil although I use the 15-50 oil during the 100 deg summers here - my vette runs oil up past 230 deg F when its running hard.

Granted, just about anything works in the turret, but, that stuff really makes it easy on the shifting.

My LS1 likes cocktails. It gets a steady diet of Castrol 0-W30 (German), 6 oz. of Valvoline SynPower oil treatment, 2-3 oz. of AutoRx; K&N long (2006) filter. Change once or twice a year. Usually in the spring after winter storage.
The 3.4L Buick (daily driver) likes Amsoil 5W-30 & 2 oz. of AutoRx; K&N (1001) filter. Change every 5,000 or 6 months.
Both engines have pre-oilers to elliminate unlubricated start-ups & invers oilers filled w/Marvel Mystery oil for top end lubrication & to keep the intake clean. Haven't had to clean the throttle body or intake since using MMO through the inverse oilers. They're awesome!

Where do you have the MMO entering the throttle body/intake?
