Every 3000 miles, or 3 months (alot of places say). Personally, I believe the truth is more in what the owners manual in your car says. For some cars, 7,500mi. may be suggested if you are just using your car for rural highway travel, in normal temperatures. 3,000mi for bumper to bumper traffic, or very hot (or cold) days, beating on your car, ect. ect. One courier driver I used to know, got 400,000mi out of a ford aerostar, changing it every 5,000 miles. MY QUESTION HERE IS WHAT ABOUT TIME? My second car got it's oil changed last December, but only has 2,000 on the oil. Does time matter that much?How often to change your motor oil in a car?myself every 3000 miles and when its changed you can tell it needed doing.
Or twice a year a have kept to this rule for years and always been fine by me although atm on this car the ol is costing a small fortune.
If you think there is some life left in your oil then see how clear it looks on the stick and leave a bit longer.
And i never and always say never buy cheap oil.You have so much running in there why would anyone want crap turning the parts.How often to change your motor oil in a car?I go by the book--chevy suburban-350-every 3000 milesHow often to change your motor oil in a car?3000 miles is right for regular oil, however, if you are running synthetic oil, then the interval can be longer.
As far as time, change it at the very least once a year in the fall, so that the oil will be able to protect the engine from the winter elements. Twice a year if you are using a straight weight oil, as the viscosity needs are different in winter than in the summer.
