'02 Bean H6, AWP & ORP, factory hitch
I'm rarely in a hurry to get anywhere (most times just leave early) but I have noticed that while going an indicated 75mph on the interstate, for example, I'm getting blown away by all other traffic. Decided to experiment. Got on the interstate one day and loaded a GPS app I have on my phone. Wow! According to my GPS, to go 70mph I have to go a speedo indicated 82mph!!! So I also tried timing myself with mile marker signs. Granted, they are probably nowhere near perfect, but in between mile markers, my odometer consistently shows 1.2 miles. I'm really intrigued now. So I ran a series of tests at different speeds, and according to 2 different GPS programs, the speedo is wrong. The faster I go, the bigger the discrepancy. At an indicated 50mph, GPS says 45. I could accept that problem as a nuisance, but realized that my odo turns 1.2 mi for every GPS indicated mile. So I ask myself, how many miles does the car REALLY have on it? I have Conti ProContact on all 4 corners, religiously rotated and nitrogen-filled. They have about 25k on them and tread depth is equal to 1/32 on all 4. So, what the ****? Speedo I really don't care about, but the odometer is incorrect. Actual mileage is now less than what the odo reads. Anybody else experienced this?
