Anyone try Valvoline off road racing oil, not VR-1, but the one for racing....they make a 10-30W in conventional oil at $5 per quart and synthetic at $8 per......more zinc. With as little as I run my car and changing 2X per year, could be an option. Although will these kill the cats?

0.02 cents from me, I do believe the issue with the ZDDP is the life span of the cats, no? Like it used to be a 50k mile warr, and now the EPA wants a 100K mile warr. I think I read that in one of the links posted recently. I'm not sure but the only thing that the ZDDP does to the cat is render the chemical reaction a no go if the ZDDP level goes beyond a set concentration point on the catalyist's grid. There maybe an issue with clogging the grid also?

Redline now has ZDPP Addative for $12.99, treating 12qts....will probably use this as I just put M1 in both cars and then go to Amsoil.

Since we don't have emissions in IL anymore and no need for CATS.
I will start using Amsoil and ZDDP Additive. Pete

Howdy, ![]() He also informed me the VR-1 is probably the better choice now. IIRC it was around the old norm of 1200 ppm and they were working on having a new synthetic out soon with good ZDDP levels in the VR-1 flavor. Their SYN Power synthetic has only around 835? ppm ZDDP, but supposedly is engineered to keep what it does have in a a healthy state or just in the engine instead of through the exhaust if I understood him correctly.
