Thanks to the EPA the large oil producers have had to remove most if not all of the zinc and other high impact wear properties in the mass produced oils and this includes the diesel oils.
If you want the true old school style racing oils that you could get before the EPA got involved go with Joe Gibbs racing oil, Idemitsu, Red line or Royal Purple. I'm running Joe Gibbs racing HR2 10-30 high zinc conventional. Or you could go with their HR4 full synthetic. Good oils come at a premium price but you get what you pay for. |
