Which oil do you use - ZR-1 Net Registry Forums

Paul,

I'm one of the guys that changes the oil in his "toy" cars every 2,000mi along w filter. Did that with the 84 also. So High Mileage or Synthetic means nothing to me. The Castrol Diesel has the ZDDP levels needed at the price of regular oil ($4.50/qt) and I've used the GTX stuff for over 30 years.
The issue of ZDDP never came up w my 84 and as you know that was a flat tappet motor. I converted over to a full roller setup in 2000 for performance not the ZDDP issue. I have posted pics of the new cams in my LT-5 motor after about 2500mi of use. Lobes look like new.
