31,000 miles is not many miles at all, you can do that with the cheapest regular gas you can buy.
I agree it's not a lot of miles and being retired I don't put on a lot of miles a year. However 31,000 miles is at least 2 years driving for most people, and I've seen threads on this forum suggesting that you use additives every 6-12 months to clean out your injectors and other gunk in your engine.
