I noticed we only had 5w-30 in the VOA vault. Personally I'm looking for a good beater oil, and even though this oil seems adequate to begin with, I was curious if anyone else had any interest. No I'm not asking for any money or anything. Just curious if I'm the only one. If I am, then I probably won't. This could be some good oil to use for the AutoRX flushes at $.835 a quart in 5 quart jugs.
