Muscle car oil?

[markjohnson]

I'm gonna try my hardest to make this my last ever post about oil! I've done lots and LOTS of research on this subject. Rotella now has REDUCED levels of zinc, just like regular oil that everyone avoids now. Now.....it was good to use for about a year or so after the EPA demanded the reduced Zinc levels in regular oil, but it was on their list to follow in having it's Zinc content reduced also. Now, I've always been a big fan of Mobil One Synthetic and if you go their website, you'll see that their "red label" Mobil One 15W-50 DOES have sufficient Zinc and is formulated for older engines. I'm gonna post a direct link to their site about it here shortly, but you can also buy this oil at any Wal-Mart and it even comes in an economical 5-quart container. Now as far as new engines or even a camshaft swap, I would highly recommend a set of EDM-ed lifters (or even a solid Roller!) and naturally a cam-break-in period of only using the outer valve springs. Yeah, I know it's a real pain in the ass to then install the inner springs afterwards, but it's just gotta be done. I had one of the first sets of the EDM solid lifters and that hole was like .012. Still in use with no problems (knock on wood!). That 'lil weephole has become extremely important in that high pressure contact area with the poor quality of today's oils.
