First measured tank on the cherokee since the restore. I have 31" off road tires on this vehicle so the odometer is not accurate. it read 178 which is actually closer to 202.92 (I have to add about 14% still working on the exact conversion.) according to the GPS when I am going 50mph on the speedo I am actually doing 57mph which if I did my math right is actually 14.00% I did 50/7 came up with 7.14 so I took 100 and divided by 7.14 and came up with 14.00% is that the correct math for the correcting value? When I have a nice sunny slow day I am going to go 10miles by mile markers and GPS and then compare that to the trip meter. So for now I am using 14% until I get a more accurate reading.
Sadly it looks like the Cherokee is also seeing a viscious hit from the fraking ethanol. 17mpg SUCKS I was getting 22-24 reliably previously (over 5 years ago) :-(
