Question about 1988 Jeep Comanche
If you have no engine leaks, you can run a 10w 30 or 20w 40 oil in your engine. I use full synthetics in all mine and add lucas engine additive as well. If you have leaks it gets expensive to use synthetics.
Always use a good quality filter ...that is the key to keeping your oil doing it's job. Change intervals should be 3,000 miles with conventional oil and 5,000 using synthetic.
