VR-1 is racing motor oil with higher zinc content which is good for flat tappet engines, especially during break-in. I used that for the break-in and the first change after that. The downside is that it is low detergent, which could eventually lead to some sludge build up. So now I put in one quart of VR-1 20-50 and four quarts of whatever name brand of 10W-30 detergent oil is on sale. My engine does not have an oil filter so I change about every 1500 miles.
