Muscle car oil?

Yeah......I thought that's what I said: [ QUOTE ]
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.

This conversation has been had on this site before and I think the uncertainty of the oils used is because everybody has had different experiences with motor oil over the years and as oil formulations have evolved chemically, more questions are asked as to there compatability to older motors which all started life out with petrolium oils. I have an original freshened up standard bore 396 which I use pennsoil 10w40 and add lucas oil additive for the cold starts. I drive maybe 200-300 miles a year and change oil yearly. I use Moble 1 in all my vehicles for the last 10 years or so and don't know if the miles driven warrent the expense. I would entertain BP or Rotella if they were proven better than the modern oils.

Brad Penn and Rotella are proven "modern" oils. Mark really said it best when he said the oil temp is very important. Don't matter what oil you have if the temp and lubrication is not right. Call BP, I did and was happy with their answers on detergents in the oil and how we drive our musclecars and the oil change intervals.
