One of the things I do when I change the oil is take the top off the filter package and using a felt pen write down the date, mileage and oil that I used when I changed the oil and then put the tops (or the backs if your using the Suzuki filters) in a plastic bag and keep them in my big tool box. This gives me a record of oil changes and makes it easy enough to figure out when the last time the oil was changed and at what miles. | Page 1 | Page 2 | Page 3 | Page 4 |
