I have allways tried to change my oil and filter every 3-4,000 miles. I will continue to do so with my H3 but maybe bump the oil change interval to 4-5,000 depending on conditions.

Think about it, If car makers made engines and cars that lasted 300k-500k miles that would hurt their sales wouldn't it?

Newer cars run much cleaner and may have better internal tolerances. Oil filters may be better too?

I have had several engines in Jeeps and Toyota go 100 to 150K w/o any problems or burning oil etc.

Now with the H3 I need a new head at 9500 miles?

Oil may not wear out but if it is dirty
