Hello ArNarX5.

I know oil flushing is not a popular remedy on this website. In two of my previous cars I used BG products for preventive maintenance.

Here are a couple of links for your review:

MotorWeek: Auto Basics: Goss' Garage

BG Products, Inc.

I see you are in Burbank. I have my X5 serviced at Center BMW. They do not have the BG service. Casa Motors in Sherman Oaks does. I had the BG oil flush done on two of my SAABs at 30k as discussed in the MotorWeek article. I did this based on my dad's recommendation, not MotorWeek. I just saw this MotorWeek episode in 2009.

I have no direct expertise in car maintenance. My dad was the mechanic, a retiree from LA City. He retired 20 years ago, so I know he was trained old-school. Funny thing, he worked on all his cars, up until his death last year at 84. The only work he would not do was related to air conditioning. Sorry for the digression.
