Re: Oil Change Intervals for your daily drivers?
Every 3k for me. I know the manufacturers have increased the mileage intervals, but I don't trust them. After all, where would they be if everyones engines lasted 300 thousand miles. They would only sell half as many cars. One of the leading reasons people buy a new car is the one they have needs a major repair...usually the engine. Keep in mind that infrequent oil changes and lack of maintanence takes life off the back end. Any of todays engines will go 120k on 7500 intervals, but I'll be willing to bet it wont go 300k. We had a Taurus in our shop that made it to 49k with no oil changes, but that was the end of it. The oil had literaly solidified in the pan.
