This fill was me cleaning out my extra quarts of oil. 3 Quarts of older M1 5w30 (SL I believe), 1 quart AmsOil 0w30, and 1 quart Redline 0w40. 80% are highway miles and the other 20% are hardcore city stop-n-go driving. Lots of idling as every road is under construction in the Pittsburgh area...

I picked up this car a few months ago. She went into the stealer for a noisy engine problem last week. I pulled an oil sample via the dipstick tube before she went in.

I pulled a 1992 Ford Bronco out of storage to try and get it running. It has about 169,000 on the clock and the brakes didn'twork at all when I got it. She sat for about a year before I got her out. Several brake lines were completely rusted through so I replaced almost all of them. She got all...

I don't know if I should dump this fill of RL 10w40 or not. Here's what happened. In May of 2004 I had to move and store my 540i. At that time I had just drained out the nine quarts of Amsoil 10w40 and replaced it with nine quarts of the RLand a fresh Mann filter. So the car sat for exactly...
