Well I'm very close to buying a 1992 mazda miasta with a pretty crappy red repaint. The car has 133k miels on it, but the owner doesn't know if the engine was replaced. The engine bay lookes very clean, so it may have. what fluids shoudl I run when I get it? I'm guessing some sort of oil that has alot of cleaning power. This car is going to become my track car so I already have Redline MT-90 ready for teh tranny and Redline 10W-30 for the next track event and guessing Redline 75w-90 for the differential (no LSD ). What else? Should I really use Auto-RX or Neutra? Is it safe for rubber seals and whatnot? Anythign else you woudl like to add?
