Engine oil

Rotella diesel oil has a lot of zinc in it. That is what I use in my 340 with a .508 cam. I get it from the shop here at work. 15W40 by the gallon.

ok first of all,, no one is ever going to agree,,,

2nd shell rotella T, 15/40 is a diesel truck oil,,,and has also been cut back on zinc,,, i run a diesel and follow all that crap too,,,because of the new emissions as of 2007 and ULTRA LOW SULFUR FUELS,,, zinc in all diesle oil has been cut back as well,,,

That is what I use in mine too. Works great. Yes, the zinc has been cut but I'm pretty sure it is still higher than the Gasoline oils. This is in a stock 318 by the way.
