I have a coupon for $10 off oil change, I can choose either full synthetic, semi-synthetic, or basic. Does it really matter, and which should I use for my toyota echo?
Synthetics are better for your engine or a high detergent conventional motor oil. I had an aveo hatchback and was running full synthetics on it and would take it back and forth to work which was a 150 mile commute daily. Never gave me any problems and ran great. hope this helps.
