Tucker2930 Posted June 24, 2006 Share Posted June 24, 2006 What brand of synthetic oil to use? Link to comment
Deans BMW Posted June 24, 2006 Share Posted June 24, 2006 Mobil 1 15-50 Synthetic, available at Wallmart. And it is an old wives tale waiting until 12,000 or some such mileage to switch over. Link to comment
flyingreg Posted June 25, 2006 Share Posted June 25, 2006 Most Syn oils are pretty good. You will get many opinions on which is best. I have been using Amsoil 20-50 for years because it works. I believe it is the only truely synthetic oil. Amsoil comes out on top of every side by side test. Link to comment
Fergie Posted June 26, 2006 Share Posted June 26, 2006 I agree with Greg. I also have been using Amsoil for years. I have heard though, that BG Products have come out with a full synthetic that they say beats Amsoil . Big question mark for me. I would wait until 6K to 10K before switching. Link to comment
Deans BMW Posted June 27, 2006 Share Posted June 27, 2006 I would wait until 6K to 10K before switching. No need to wait at all. Link to comment
jdos2 Posted June 29, 2006 Share Posted June 29, 2006 No need for the dealership recommended 3k oil changes, either. They still had my ST on the floor (8k recommended oil changes!) and tried to tell me that I should change mine at 3,000 miles. I asked if the tranny ran in the engine oil like the ST (and reminded them of the 8,000 mile recommended changes)? Razor blades? A special oil-sheer attachment inside the engine? They just shrugged, like I'm going to do when I try to buy an oil filter wrench from 'em. I'm going to use Delvac (Silver bottle). Always have. Link to comment
