Gas mileage

[89Suburban]

I made a recent highway run down the turnpike and got 12 MPG at best...

You can not rely on GPS to give you exact mileage. In general they only report your position every 15 seconds. If yo make a right turn between those points it won’t show the exact turn, rather it will reflect a diagonal line. I know this as I watch GPS on 3000+ vehicles... on any given day, we see a variance of up to 200 miles versus reported odometer report... The GPS is close, but not exact

Good info, but I bet a GPS is a whole lot more accurate than the odometer on a vehicle with non-standard tire size.

Well, how do you account for the navigation systems knowing that you just made or missed a scheduled turn?

Doing 90?

Well how long does it take to go through a turn? 5-15 seconds (roughly)? As long as the GPS has your route on it, doesn't it know you were on the road? I know even on my little handheld that's 15 years old that I have never updated the routes on, that when I take a road different than the route given, it adjusts my path after and keeps me on the road. It doesn't just create diagonal lines to put me on a new road like you claim. (Which even if it did, were talking maybe 20-30 feet??) You are saying it as if people fly through right turns on 90 degree corners, and that the GPS doesn't adjust to keep your path on the road, that's not true.

200 miles reported versus a person's verbal report, or 200 miles versus electronic communication between the vehicle??? Either way, that is flat out horse shit... The tire size needed to make that much of a difference wouldn't fit or be reasonable to put on a commercial vehicle. The gearing is not being changed from the factory to compensate the difference needed to make up 200 miles in one day. If this much was being done on a commercial vehicle then calibrating the cluster would be vital to be knowledgeable and not something that would be left up for someone else to figure out. Commercial drivers are not putting that many miles on in a single day to where a 200 mile difference would be a reasonable variance.


The only thing that makes that even close to being possible, is if your drivers are trying to cheat you out of mileage.. That is NOT something you should be putting on a GPS.

you got cats on it still? sounds like they be going out maybe.

Yes I think they are the originals. Very strict annual emissions testing here. I got 310K on it.

id get them swapped out, and some new o2 sensors if those are original as well. bet she feels almost new after that.

Holy shit, are you still on the same transmission?
