Terribles should stop requesting oil changes every 3000 miles with synthetic oil. It is common knowledge in the auto industry that Synthetic oil lasts between 6000-9000 miles between oil changes. Synthetic oil is more expensive than regular oil but it lasts much longer, however, Terribles still gives the little sticker to remind you to return after only 3000 miles. I've gone to Terribles for oil changes for several years and told them to give me a sticker to return after 7000 but they said no that's our policy. Word to the wise, don't listen to Terribles and get your synthetic oil changed between 6000-9000 miles.
