The way I read the owners manual, it's OK to change oil at 6,000 mile intervals even if you're using ordinary petroleum-based oil.2wheeler said:
I used Castrol Syntec, and changed every 6K. It is a great oil, and I could get it closer to home, for a little less money than the BMW synth. I had been using earlier.2wheeler said:
BrianD said:On a related note, does anyone use oil in their drive shaft. Normally it is a "dry" shaft I think, but when I had the rear end drive fail, my mechanic put full racing synthetic oil in the rear end drive and about 150mls into the drive shaft as well because he noticed all the grease had spun off from the joint. So far there is no problems, just wondered if others had done this too, and what everyones thoughts are.
The Final Drive oil should be changed at least every 6K (and I sometimes do it earlier if I am going on a long trip or just completed a long one). It is cheap insurance against destroying the complete final drive unit (takes just 1/4 qt.) . That way you can keep an eye on the condition of the oil coming out, checking for excessive metallic flakes--- a sure sign of the bearing going south. I caught mine at 96K and got by with just replacing the bearing and am now at 118K.2wheeler said:Is the tranny necessary every 6K? Manual says every 12K.
1) To quote from Caterpillar: "No corrective action required" at 10K intervals.rglassma said:What is your usual results of the oil at 10K intervals?
What is your driving style?
What is your average mpg?
