4.23 essentially references "dry fill", meaning that's the amount of oil it would take if you could suck practically all the oil out. I'll let mine drain for 30 minutes and add 4 quarts and it'll still be overfilled. It's normal.I get that but then it'd be even MORE over! :mask:
I'm convinced that the 5W-20 recommendation is just to keep the EPA happy. In theory, you'll burn slightly less fuel using 5W-20. That has not been the case in practice, in my experience. (I did, however, burn some oil using 5W-20. Switching to 5W-30 solved that problem, too.)Thanks all! I'll stick to 4 quarts! And I agree I just went from 5w-20 to 5w-30 and its quieter! Was just to lower the TINY bit of oil I'm burning with thicker oil. Will try 10w-30 next! Not sure how good I feel running 10w-30 in the winter but... In the summer its all good!
