Not sure what you mean when you say that you are looking for a better motor oil? What are you using now? The BMW synthetic 5w-30 is pretty good but I also use Valvoline or Castrol 5w-30 with very good results as well. Many people will tell you that you must use an oil that has the BMW LL-01 approval but if you change the oil twice a year like I do, any high quality full synthetic 5w-30 will work just fine. I've found Wal-Mart has the best prices on their 5 quart containers--often at around $20-$22 each.

Second that on not sure what "better results" is defined as. You have 68K on it, and unless you have done a tear down to check journals and bearings etc, not sure what better results you need. The secret to better, or perhaps longer results is more frequent oil changes...and the BMW oil will be fine if not more than fine. If you wish to compete in the car, that may be a different story...so not sure what results you are looking for. Good luck on the quest...

I'm still not sure what you are looking for. How do you measure "better results". Are you sending your oil to Blackstone or some other lab for analysis? Personally, I've used the synthetics noted above in BMW's changing the oil every 5-7k miles and gotten over 250k out of the engine with no major work done. I don't know what can be "better" than that.

The BMW/Castrol oil is great! I do favor Mobil1 since it's a bit cheaper and easier to find.
Here's an analysis I did on the BMW I drained out. In a couple more thousand miles I'm going to drain out the Mobil1 so I have an apples:apples comparo. http://www.bobistheoilguy.com/forums...13#Post2137613 |
