Good stuff

Arrived quickly . Claims to have Zinc content for flat tappet engines . Has a strange blue color . I assume thats normal . Used for my old tractor. Won't know long term effects for some time but I understand it is better than using low zinc fo rmodern engines. However normal oil pressure , no weird noises so seems to work. Would recommend fo older engines .

We have several older vehicles that require oil with Zinc to prevent excess wear on the cam and lifters and have been using Valvoline VR-1 for years with great success. The cost is right in line with the competitive conventional oils in the market and this product is synthetic as well as having plenty of Zinc content.

only ever run this in my Prelude's H series, has a high zinc content for the sake of your flat tappets and cams, just wish it came in 5w30 :(

I think as long as you use a quality oil its hard to go wrong. I use this in a flat tappet cam gen IV BBC and the car still runs great. I think this is probably one of the better values in high grade performance oils.
