Rich Kinsley '64 Dodge Polara 4dr 318poly w/goodies Ok I know this is a well worn subject but I want to be sure. I am changing from the Rotella 20-50 to Valvoline VR-1 straight 30wt. Unless I am mislead I recall that Don D and others prefer the straight weights and so have I. The VR-1 does have the Zddp in extra quantities per the label and literature. I think the 30wt will do a better job also. The price is a bit more but still very doable at $4.96qt at NAPA. This car does not see cold weather, no heater, so the oil is not too thick. I hope this doesn't cause a riot :-) I'm just trying to be sure. ---- Please address private mail -- mail of interest to only one person -- directly to that person.
