Oil changes will improve your engines performance. You should complete an oil change at least once per year , when you have your car serviced. Ensure that the oil used is of the highest grade and is the recommended grade for your vehicle. If you drive in normal conditions then change your oil/filter every 5,000 miles if you use conventional oil or every 8,000 miles if you use synthetic oil.
1992 what? you DONT say what type of vehicle, what's a 4r? 4r is NOT a vehicle I have ever heard of or have ever worked on, be more specific!.. Also How many miles are on your vehicle, Is your vehicle equiped with a manual or automatic transmission? When was the last time you had your transmission serviced? Automatic Tranny fluid and filter SHOULD be changed anywhere from 15,000 to 25,000 miles on most vehicles!
