Do you do them, such as when you fill up for gas for just get bored. The reasoning for asking was I had to do a trip from Kansas City to Oklahoma City pulling a 16" trailer with a Eclipse full of boxes including the truck. Pulled over to fill up for gas in Wichita and I do what I normally do while pulling a trailer, first check the trailer...everything good, open up the hood the air filter is laying under the intake and partially in fender (It's a Air Force One intake). The kicker is that I had 100+ miles to go and the return trip also, had a big stash of oil and filters. The oil in it is Havoline 5w-20 will 2500 miles.. hadn't even color yet.. what a waste. Anyways my family thinks i'm a worry wart but I going to start doing this on all vehicles while waiting for the tank to fill.
