Hello to all the Previa buffs out there! I am a new owner of a very nice 94 previa AllTrac S/C. I have no way to verify how the car was taken care of before, but since it runs very well I am happy to have it. One question though - I spoke with the dealer about the supercharger oil and he told me they never change it, they only add to it if it is low. That sounds a little strange to me, and since I would like to get it right before I pay him money... - What is your take on it? Does Toyota require the Supercharger oil replaces every so often, or just topped off? Thanks, Eugene
