#1 change your oil as often as you can and as much as your budget allows. With that said, I use Mobil 1 and Mobil 1 Extended Performance depending on pricing. I think that if Mobil 1 is good enough for Mercedes then it is good enough for me. And it costs about $26 for 10 qts of Mobil 1 Extended Performance and ~$4 for the Motorcraft FL-820S filter. I only spend about $22 per oil change at ~7000 miles.
Where are you buying 10 qts of Mobil 1 for $26.00? That's a great price!
