See below. Just saw the reply. Is FM / EP that is in Redlines Oil that bad....I changed the oil out at 3200 miles, and also at 6500 miles just last weekend again with Redline 5W30. I would have figuered the *initial* break in for the rings would have been taken place after 3000+ miles. I varied the RPM (and still do) up to 5K to help the rings set properly. Just new to this but any advice is greatly appreciated ! ____________________ Ugh, why would you void your warranty with Redline? Unless you do a lot of specialized racing, Redline is NOT the oil of choice. Get it out, not for extended drains. Why did you change factory fill at 3k anyway? Isn't the BMW interval 15,000 miles? Your engine will not break-in properly with fresh oil that has tons of FM and EP, bad move. Your rings have to seat while there is cross-hatching still in the cylinder bore. Honestly, at this point, I'd put in a DINO oil and drive it hard, low revs and deep throttle, seat those rings. I guess you *could* just change to a BMW or ACEA A3 approved oil like, M1 0w-40 (not my fav) GC or regular ACEA A3 Syntec 10w-40 or 5w-30. Redline is for cars like nitrous V-tec Civics. Timing-wise, my opinion is 6 month intervals are best, up to 8,000 miles each. Fresh oil for the cold of winter and heat of the summer means changing in Nov and May, forget about miles.
