oil change - oil recommendation

[micjordan]

can somebody give me a quick oil recommendation (brand/type) for a 93 740 oil change. when i was buying the filter at the dealer the guy specifically said not to use synthetic but just to pick any regular 10w30. is this correct? i thought synthetic was the way to go.

all we use in bmw v8s at my shop is mobil 1 synthetic 10w40 or 10w30 at about 6k miles, you could probably use regular oil with no problems at all just change it at 3k miles

Guy at the dealer is wrong. Use a 0w-40 or 5w-40 synthetic at 7500 mile change intervals, with preference for Mobil 1 0w-40. If you choose to use Mineral oil, use the weight recommended in your manual, which will call for 10w-40 for temps below 50F. Most likely depending on where you live, 15w-40 would be a good year around choice for mineral oil.

I just switched from dino oil to Mobil 1 0W-40. BIG Difference!! Runs smoother.

Your owners manua will tell you what viscosity to use. It depends on the temprature of your locale.

My dealer switched to synthetic oil for all models about 5 years ago. I have 130,000 miles on a M50tu and have had no problems after the switch which was abour 50000 miles ago

Note: In my post above I said 10w-40 and it should have said 10w-30 mineral is for temps below 50F. The rule is follow the weight guidelines in your manual for mineral oils, and for Synthetics look for a 0w-40 or 5w-40 (or if you can find it ow-30 or 5w-30) that are ACEA A3 and/or BMW LL approved. These oils are sutable for year round use in all climates. Specific oils that meet this are Mobil 1 0w-40, BMW Synthetic, the rare German Manufactured Castrol 0w-30 (red label, says made in Germany on the back), and Valvoline 5w-40 Synpower are a few that meet these specs.

Autozone seems to be the most reliable supplier, but if you look on Bobistheoilguy.com you will see many people still can't find it.
