http://www.joegibbshotrodoil.com/hotrod/index.html I'm thinking about trying this suff and some of thier break in oil in my new 408 I'm building.....just looking for some opinions. It's a little over $7 a qt. but I only change oil in my '35 one a year anyway. After 12 years I still have to look closely to see the oil on the dipstick:3dSMILE:so I don't change it too often.
Never heard of it. I'll stick with the big boys who have been around forever and have bizillions of bucks invested in research. I use Lucas in my HD; Shell Rotella in my Cobra because of it's zinc content needed for solid lifters; Mercruiser oil in the boat;and Casterol in my Chevy 350 and Xterra (just gotta get more toys!). Not a huge fan of synthetics although I have used Royal Purple in the past. I change oil often enough so that it's not worth the money for synthetics.
i have used the joe gibbs oil for break in oil it good stuff. one of the BIG BOYS makes it for them
I have'nt ever used it but you can bet your arse that if Joe Gibbs puts his name on it that it'll be pretty good stuff.
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.Quote:

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!
