Yeah, that can be a pain. For the record, Castol is a quality product, as are all modern motor oils, the rest is marketing hype. What kind of warranty do you have that says you have to change the oil every six months? What if a person drives 40,000 miles a year, I know many people who do. That would be an oil change every 20,000 miles. Oil changes should be based upon miles driven. If my GC is 6 years old but only has 10,400 miles on it how many times should I have changed the oil in 6 years? Answer twice.
How Long Does Your Oil Last In Your Car
The other nuance concerns how long your oil is good for in your engine - how long it "lasts" in your car. Again, this is situation-dependent, because driving conditions are the biggest determiner of how long oil lasts in your engine. That doesn’t mean you need to change your oil after 3000 miles on the clock. The best answer to this question is found in your vehicle’s owner’s manual. The most common answer to the oil change interval question is 7,000 miles. This goes down to 5,000 miles if you fall under the “severe driving conditions” – lot of short trips, very hot or very cold driving conditions, very dusty conditions. Your vehicle owner’s manual will give you the right answer to this question.
