Of course. All oil wear out.There are 4 most important maintenance items in your engine and tranny (the most expensive parts of the car).(1) engine oil (3k - 5K miles)(2) tranny oil (30K miles)(3) coolant (3 years)(4) timing belt (60K miles)Just keep those maintenance and your engine and tranny will be problem free. I have a 94 Civic with 187K miles and the engine + tranny + suspension runs like new. I get 41 MPG (doing 72 MPH). I can get even better MPG doing 55.Good maintenance pays off.Good Luck...
