I use Mobil One Oil and I swear buy it. I throw papers and put 30,000 miles a year on my Nissan and I also use synthentic tranny and gear oil( usually mobil, put I have used royal purple). My truck has a 5 speed. I have no visible sludge, I change my oil at 3500 to 4000 miles. i do it myself. If I didn't use my truck like i do i would go to 5000 to 7000 mile oil changes. What do you all think of Mobil one oil.
