5,000 miles for the truck Once a year for the wife's car. Hoping it'll die so we can get the 2011 Mustang.
I change both my '96 and the fieances' '05 Xterra every 5000 miles. Both use Mobil 1 Full Syn with a Mobil 1 filter but hers uses 5w30 mine used 15w50 and has been since 10k ago on my new engine.
just now seen this.. I went with 7500.. but usually ends up between 5-7500 using Valvoline Full Syn this last time, but generally Mobil 1 Full Syn. But I keep an eye on my oil and temps to make sure everything is good!
I used to be the one changing oil in the rigs until I joined the Navy (I am NWSCREW's son for those who haven't noticed) For all 3 rigs, it's 5000 miles. The F150 and the Mustang both use Mobil1 Full Synthetic while the Cavalier uses cheap oil (usually Napa oil)
I just changed mine yesterday at 3200 miles using full synthetic Valvoline, and a Purolator Pure One filter.
