Thanks bro. I will try this app. I was using android speedometer and this has decimals which was very helpful. I'm positive that 8208 is OFF for VX with 175 tires. Andrzej was right. Test your numbers. I think 8094 is correct number. BTW do not change your PSI tire pressure when doing any of those test. I'm sure that affect MPGS as well. I will test on the way back the mileage and mpg and let you know.
