After a service visit here's the email I sent to the shop (what do you think):


Hello,



I had my oil changed today among other things and noticed the use of Quaker State European 5w-40 Synthetic, I've never use this brand of oil and didn't know it was approved for my E66, when I checked the BMW site I didn't find it on the recomended list and I noticed a sticker on my windshield that states an oil change is due in 7,500 miles while my car states 15,000. Can you advice on this? Here's what I found and the link:

Thank you,

Here's his reply:



Thanks for the email.

Quaker State is a European blend that is used in Porsche, Mercedes, BMW . It is actually better than the oils on the recommended list. Castrol is used in the motorsports cars because Castrol is the only one that makes the 10W60 oil.

The consumer should have their oil changed in their vehicles every 6000 miles. We have seen nightmares when people wait for their “free” 15,000 mile service. The oil turns to sludge sometimes, it can ruin crank cases and vacuum hoses, etc. PLUS it is good to have someone just look over your car before 15000 miles just in case a hose is getting ready to blow, your tire pressure is off, and other things waiting to happen that the customer is unaware of. The 15000 miles service is unjust to the consumer. It is doing no one any favors except for the people who give it away for “free.”

I hope this answers your questions. If it doesn’t, let me know. Thanks a lot.
