Great question, I would have to say yes. Actually, I will back pedal some on this one, I was thinking about warm running conditions/noise on the M96-M97 engine, but the start-up noise does seem slightly better with the 5w-40 weight lubricants. The greatest growing concern of mine right now is the M96-M97 IMS chain tensioner. If it were mine, I would replace that tensioner every 40k miles. Jake has seen catastrophic engine damage occur when the IMS chain tensioner has worn-out and left loose for too long. Listen for ratting noises on cold engine start-up, this can be indicative of a worn out IMS chain tensioner. It’s now on my list of preventive maintenance items, not to be taken lightly.
Good luck,
