Today I did my 2nd drain/refill. I plan on doing a couple drain/refills over the next couple weeks to swap out what I'm sure is factory fill. With Mobil1 being $10 a qt, I'm wondering if there is a (quality) cheaper alternative. I'm all for getting quality products, so if $10 is the good stuff, $10 it is.
