Re: Which oil do you use
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. |

Dom, have you compared the ZDDP data from a few yrs ago vs today's levels in the Castrol you're buying? I'm told that the levels were dropped when catalytic converters were required on the big rigs.

Re: Which oil do you use
Also
"BTW - The Castrol Rep also told me that the Castrol Diesel 15W-40 oil has a higher flash and shear point than the Castrol 10W-40 and 20W-50 oil I have been using in the Old Broad since she was new. Great!!! That way I don't have to worry about coking of the oil in the turbo oil cavity in the summer or winter especially after running her hard on the freeways or the streets in the summer." ....Comment on Feb 2012 |

Re: Which oil do you use
Good to hear, Dom. I was just wondering about that after a discussion with my engine guy today. Do you have cats?

Re: Which oil do you use
I generally like a heavy body Olive with a little oregano and plenty of garlic.
