1. Dont use Fram oil filters if you have a choice. 2. 3,000 mile oil change interval is a myth. Oils last alot longer than before 3. Use synthetic oil. It's the best oil for your car. It doesnt cost that much more. On average, Keep it in there for 6,000 to 7,000 miles 4. You Must Read the Used Oil Analysis Section. It's the #1 piece of information that gives you an idea of the health of your engine. I equate it to a doctor's check up where they draw your blood and send it to a lab to assess your health 5. Buy your own oil and oil filter and pay a mechanic $8 to put it in if you cant do it yourself! 6. Any time a repair shop changes your oil. Specifically ask them the brand of oil and filter. Make sure it's the best quality oil and filter. 7. Take a quick peek under your oil cap. It only takes 2 seconds. Know how to recognize if there is sludge there. Use AutoRx if there is sludge. 8. I thought I was an oil change freak! I now know im not the only one.
