Okay, well how does it keep track of when you need to service your engine? Take oil for an example. Do you update it when you change your oil then it just counts down 3,000 miles or can it tell you when oil is in need of replacement due to the condition of it.

My next question is about the trouble codes. It says it tells you clear trouble codes. How clear are the codes. Will it still give me numbers like the diagnostics tests at autozone ones at autozone or will it actually tell you what the problem is without having to look up the meaning to codes?

Last question how accurate is the diagnostics scanner? For example I have a bad vaccum hose on my truck and it keeps giving my truck the codes for a bad MAFS. Would the UG have picked up on the hose being bad or would it have gave the codes for MAFS?
