I was told by my old local Toyota shop (Rambo Motors, Portland Ore) that some oils, such as Pennzoil, are paraffin based. They said it wasn't a problem as long as most driving was long/far enough to completely heat the oil. If short drives were the norm, it would begin to muck up things. They used and recommended Valvoline. ...tektronix!tekid!bentonh ...teklabs!/
