how do you check oil life since last oil change
3 Answers
It is best to change your oil every 5,000 miles. If your car has the oil service monitor your owners manual should tell you how to check the percentage.

Oil/filter change before it gets past starting to turn dark if your not keep track of miles, never let it turn black.
Like the first post says, change oil and filter every 5000 miles. I recommend you get a little book that fits in your glove compartment and write down the date, mileage and the maintenance you did. Tuck your tire and battery receipts and tire warranty in to the back of the book. Beside that, put a drop of oil on a sheet of paper and look at it with a 5x magnifier. Compare what you see with a drop of clean motor oil. Look at a drop of ATF from your transmission dipstick.
