What is the best oil for the beast. - ZR-1 Net Registry Forums

soslow · 10-25-2009

I have a 1990 ZR-1 with only 7500 miles. So far I have been using Mobil-1. I read that most oil companies removed the zinc from the oil formulations because it destroys the catalytic converters but zinc was the ingredient that afforded the most protection to the cams. Does anyone have any ideas what the best oil would be for the beast? I heard that Hy-per lube sells a zinc replacement additive, but you need 2 bottles at twenty bucks each for the 12 quart capacity LT-5. I want to use the best oil available, without resorting to expensive additives that may or may not work. Any input from my Beast Brothers?
