switching to synthetic

demon seed, I agree with all points but the oil leak thing. Being synthetic oil molecules are larger than air molecules if a motor will leak when sythetic oil is put in, it means that air and dirt can get into the motor. This is not a very well gasketed/sealed motor and has/will have bigger problems than an oil leak. I run sythetic or synthetic blend in all of my vehicles including lawn mowers and farm equipment regardless of age and have no issues with leaking.

I would also add that the gaskets and seals that we put in our older cars are no different than the gaskets and seals in the newer cars.
