I've never tried it. I know it's probably overkill for my accord. I wanna try it. Lol I currently run magnatec 5w30 in my accord 2.0t, so I'd probably go with the RL 0w20 since the 5w30 is a bit thick for something that specs 0w20. Is RL still using high calcium? Any issues in a tgdi engine? Open to any insight.
