25,000 miles is maintenance schedule for trans and diff, especially in populated metropolis driving. I'm currently using Mobil 1 however some some research I no longer will be, apparently it has horrible viscosity duration, therefore I'm going to just use Motorcraft synthblend. I also may start using Lucas oil stabilizer like 25% of the bottle at a time. I poured a bottle into my 93 tracer and the horrible valvetrain rattle is gone.
