hey guys i just purchased a 99 infiniti g20 with 210k on it. im looking to see how far i can extend the oc out. usually i do a oil analysis when i extend my oc but not willing to do it on this beater. any ideas on what oil and mileage i can use? im hoping for a 7500 oc hopefully. i was thinking about the mobil ep deals they usually have with the oil change specials. any ideas? thanks guys.
