Not Ranked
I use the VR-1 20-50 Racing oil and it works very well in my 428CJ. The engine prefers it to the synthetics. I have solid lifters. VR-1 has a high zinc content, if you have a newer engine and are running catalytic converters it may not be a good choice, as the high zinc content will not work well with the cats.
