Thread: What do you guys think of this oil?

Tweet

And the BIG BOYS are keeping cam grinders in business. I'm just not sold on diesel oil...A lot of mixed opinions are floating around on that one. I'm trying to get the scoop on it though.

Don Shillady is a respected member of the board here at CHR. He is also a PhD Chemist and Professor and rates all the respect I can muster.

Don did extensive research when this ZDDP elimination in oils reared its ugly head and came on here to recommend a commercially-available oil additive that he had discovered.

Directions are 1 1/2 ounces to each quart of oil for cam break-in and 1 ounce to each quart of oil with subsequent changes. I used it to break in the cam in the 6-banger Ford motor I rebuilt last year and all is well so far. I now use it in all my rolling stock. Now, I just buy what's on sale for oil and put the SFR in with it. As the Aussies would say, no worries mate.

I'd have to second what Tech said, it's costly but worth it.

Due to bearing damage, and the necessary teardown, I am taking the opportunity to change to a roller cam. Wouldn't that eliminate the need for special oil additives?

That is correct.

Still recommended for initial engine break-in. EOS type additives coat surfaces and enhance protection for the first few hundred miles. Also if you have oiling issues on initial start-up the additive will reduce the level of damage throughout the engine (assuming you catch it very quickly).

Chevy ships EOS to use with all its roller crate motors.

I use a Comp Cams additive for break in that has a pretty good reputation. It kept my flat tappet cam from going bad at least!
