Question for Mr. Roberts and others.......
RRoberts said:
My car is an early 2001. I started using 10w-60 oil at the 1200 mile change, at the advice of the SA, despite the 5w-30 sticker and the information provided in the owner's manual. I have been using this oil ever since. I change oil at 3-4000 mile intervals. The car has 17,000 miles, and is typically down about 1/2 quart at oil change time. I have never needed to add oil, including track use. I see no reason to use any other oil than Castrol TWS 10w-60 in this engine.
I know opinions vary on this subject, with many factors cited pro and con.

I would rather have the heavier weight oil dumped into my motor, over the 5W-30 grade engine oil, but here's my situation.
When you open the engine hood on my 2003 model M5, there's a sticker which tells the technician to use the 5W-30 weight motor oil, instead of the 10W-60 oil.
Being that my car has the full maintenance, the dealer does the oil changed for free every 15,000. I pay for the oil change/service at the 5000 mile mark,so I pay for the oil change twice before the dealer does it for free which would be at the 15000 mile mark. I want to stay consistant with the oil changes, in other words I wouldn't want to have the dealer do the free oil change using the lighter 5W-30 weight oil, and then I have it changed 5000 miles later and tell them to use the heavier oil. Im not sure this would be good for the motor. :confused3
Obviously the lighter motor oil is less expensive for the dealer, so how do I convince them to use the more expensive 10W-60 engine oil and put it under the maintenance plan, charging BMW for this type of oil change. Im sure the dealer will tell me they will not get paid by BMW for the more expensive motor oil, so they will make me pay for the supposed "free" oil change. How do I convince the dealer to use the 10W-60 weight oil???
I tried this once ( a long time ago) and the service dept. told me they have a notice for my model year car to only use the lighter of the two motor oils. Guys what can I do??? Please help with advise on this matter.
Thank you.
