VR1 Racing Oil (VR1) 10w30 be good to run in a 22re? all year long. Am thinking about when I change the oil to use this oil. I think 20w50 would be to thick, and straight 30w wont be as good as muiltgrade? Thx
You can likely get away with any 0w-30, 5w-30, or 10w-30 year around, I would stick with a 5w-30 because it protects better at start up than a 10w-30 and not as expensive as the synthetic 0w stuff. If you want thicker oil, then get something like a 5w-40 or 10w-40, but you shouldn't need anything thicker than that unless your engine is in poor condition. Straight weight is a bad plan and doesn't protect well at start up where most wear happens.
I also wouldn't use a racing oil year around simply because racing applications are not designed with long drain intervals in mind so they may not have the same levels of detergents. Pennzoil Platinum would be a solid option for a year around solution.
