Re: Oil and Filter Recommendation
In the past I have used nothing but Synthetic, true PAO synthetics, Amsoil, Mobile1, Royal Purple. If you are buying synthetic make sure it is a TRUE synthetic.
I no longer run it in my engine on the BMW. I use good old Dino Castrol 20-50W or 10-40W now in Fall/Winter.
Still use Amsoil in the FD 80-90W and 75-140 in the Tranny. I also add 1 TSP of strait Moly to the FD.
I change engine oil too often to use Synth as it is for extended drains. A waste of money. I do all my fluids every 3000 miles, and while a lot will say a waste, it makes me comfortable.
Filters I use Bosh from Rock Auto at 3.37 each.
These things do not care what flavor you use as long as it meets specs.
As far as dealer support I tried, no matter how hard you do, the Dealer is going to get you one way or another. In these economic times they are desperate and it makes them greedy. Not all I know, but can you really trust them?
Use a good oil in the motor, synth in the FD and Tranny. While 75-140 does work in the FD the Spec is 90 W I believe. So a quart of Amsoil 80-90 does the FD 4 times, and a 3/4 quart for the Tranny.
