I had to drop my truck off at the shop this morning and hand over the keys. The instructions were... The check engine light is on but it is running perfectly, and don't worry about the oil because I changed that 100 miles ago. I'm at work so I had my father fields the calls. It comes a few hours later... Shop: With this high mileage, we'll be changing a doohicky on the emissions system, the fuel filter, oil, air filter, the spark plugs and wires and (pretty much everything). Dad: What do you mean, high mileage? Shop: Just over 89000. (My zip code.) Dad: I think the truck has just over 48000 miles and I changed the oil the day before yesterday. Shop: Well, I'll check that out. An hour later. Shop: Okay, just the emissions system, and fuel filter. An hour later. Shop: Why didn't you tell us the clutch light is on? Dad: It wasn't. Never has been. Shop: Well, I'll check that out. Tomorrow morning ought to be interesting. I get off work too late to have picked it
