[QUOTE="Jomax, post: 1410468, member: 376"] I'm running M1 syn 5w40 no tick. And I'm @ 67k miles. Will be at 70k in a couple weeks. I change every 5k I've been meaning to try LE, but every time I remember, I need an oil change and need it now lol... been doing this since 30k miles LOL. Sent from my iPhone using Tapatalk [/QUOTE]
