Best Engine Oil?

[cannonfodder]

Hey guys what is the best engine oil in your opinion for our 1952 M135 CDN?

 

[gimpyrobb]

Whatever you can afford.

Any 30W..... really in a gasser you can run anything you want. 5W30 ect.....

x2 on that. dont be too worried about the brand/type of oil, as long as its wet and slippery it will be just fine!

As long as you meet the grade and spec's of whatever the TM recommends, brand doesn't make much difference.
Related story: Ten years or fifteen years ago, I built and drag-raced a "funny-bike". Kawasaki, 450 hp, fuel injected, alcohol, supercharged, 11 slick, The bike went 165 mph at 8.20 on its third qualifying pass. ( It was capable of about 7.00 at 175 at sea level) I had to change oil every time I started it. Period.
Anyway, at one of the big racing events at our local track, a racing buddy of mine and I were talking to one of the top funny car drivers of all time. We asked him what was the best brand of oil. If anyone should know, he should. After all, 6000 horsepower pretty well will decide what is a good oil and what isn't.
Without hesitation, he replied "as long as you meet the engine's spec's, whatever they give you for free...".
I studied what would work best in my Goat, as that has an aluminum 353 two stroke diesel. Apparently, straight weights work better in older engines. I forget the reasoning.
I like Rotella.

old, low-tech engines (like your m35 gasser) pretty much expect oil in the crankcase. Not much more than that is required. Modern tribology didn't exist when that engine was designed. Meet the viscosity requirements and change at the recommended interval.

I wouldn't be afraid to run used centrifuged oil in an older motor, as long as the viscosity was OK.

Did I mention I love motor oil threads?
