Great Stuff

I have been using Mobile 1 Extended Performance 5w-30 in both my BMW and my Toyota for the last several years. Mobile 1 is recommended and original equipment in my BMW and has been great in the Toyota. I only drive each vehicle about 7-8k miles per year, but have had no problems going 12 months before changing. I also like the fact that less frequent oil changes are better for the environment. The extra cost of full synthetic oil is well worth it.
