speaking of synthetic switchovers
I'm at 33,000 mi and I've been thinking of switching from ole'fashioned oil to synthetic (probably mobil 1). but I've been afraid of the seal leakage... Are there any things that can be done to avoid replacing the seals? I heard of people doing half-regular half-synthetic for a few thousand miles before going full-synth, but I'm not sure if that's just an old wives' tale or if it actually makes a difference. Any suggestions on this?
