Simple question. GTL manual says 5W40 or 10W50. This weight is not easy to find here, (I can find 5W30 or 10W40) what alternate do I use? Other than ordering from BMW.
Garry, they are specifying RACING oil. These oils have special additives and a higher concentration of zinc. I would bite the bullet and get the BMW oil until you find a suitable equivalent. Don't be a penny wise and dollar foolish.garry_kramer said:Here is the page from the manual
The owners manual recommendation is from the BMW mothership in Germany. If you read the label carefully on the BMW-branded 5W-40 bottle here in the US (made by Spectrol), it clearly states oil tested and qualified by BMWNA.PHILBERT40 said:
Spectro makes the BMW-branded full synthetic 5W-40 oil sold here in the US, so no surprise there. Right on the label.PHILBERT40 said:
