Not to hijack the thread, but if you really calculate it out, Mobil 1 isn't that expensive of an investment.
Mobil 1, 6 quarts ($24-Walmart) + $3.50 filter=$27.50 total
Namebrand dino: 6 quarts ($1.90/qt) +$3.50 filter=$14.90 tot
Mobil 1: 5000miles/$27.50= roughly 182 miles/dollar
dino: 3000miles/$14.90= rougly 201miles/dollar
In my mind, it isn't as expensive as people try to make it. Furthermore, I think it'd be a more logical argument to use dino oil instead of synthetic as a substitute for double plat plugs. Just my pov.
