Improving mileage in the V-Cross

[Cobrajet]

This may very well be my solutions to fuel mileage issue...

29 city/36 highway. 172 turbocharged horses, and only 2660 pounds. 15 second quarter mile, 0-60 in 6.7 seconds.

My VX has served me well for the last 100K miles and she deserves a rest. I'll still keep her, in the garage, with the Mini, my Cobra and my CBR600F4.

(Sat in the Mini today -- FORGET IT!! -- I'll keep my gas guzzling COMFORTABLE VX!)

My Bf says we got 26 miles per gallon on the highway driving my VX, home from Dallas. Is that possible?

i would very very seriously doubt it, how did he calculate that? run the gas tank til empty, fill it up and divide the miles by 22 gallon tank? the fuel gauge in the vx is notoriously inaccurate, the only true way to check your fuel economy is to fill your tank completely (dont put extra in after the pump stops on its own) reset your trip odometer, drive around, next time you fill up, fill it up until thet pump stops on its own, dont put any more in, look on the pump to see how many gallons you put in, divide the number of miles on your trip odometer by the number of gallons u put in (140 miles divided by 11.6gallons = 12.06 mpg) sorry if this is just telling you what you already know, i just like to explain things fully

i thought i was getting like 22mpg for awhile.. turns out the scangauge i was using to calculate it was set wrong.. i was actually around 16mpg

Remember... When calculating your trip odometer you have to adjust for the tire size if you've changed it...

For instance.. I just filled up today... 20.8 gallons... I had 315 on the trip

Because of my tires, 315 is really 346.5
I get that from the fact that when I'm going 60 on my speedo, I'm actually at 66... so 66*315/60 = 346.5

346.5/20.8 = 16.65 mpg for this tank

not 15.14 which some may have thought

SO maybe 13 mpg is really someone getting 15 or 16 with 33 inch tires... ?

You can use the infamous miata tire size calc to figure out your speedo difference from stock tires to your new tires...

btw.. who's getting 23? are you running 13 inch wheels and tiny tires?

We didn't do the usual test because we wanted to see how many gallons it took to drive home from Dallas, about an hour away. We topped off the tank drove home, topped it off again and calculated from how much we added which was 2 gallons to drive 52 miles. But I was wondering if you can get an accurate reading in such a short distance.

At the time we had bald tires, same size that originally came on the vehicle. We didn't get new tires till the second day we had it.

I filled mine yesterday and had 16.9 mpg. Thats a little better than normal. It usually runs 16 to 16.5. That is a combination of city and highway driving about 50/50. The tires are about 1/2 inch taller than stock. I am going to be going back to stock rims and tires this weekend. Biju gave me a killer deal on the tires he had. So maybe in the next week or so I will be able to tell if there is any difference with such a small difference in tire size. At one point just after I bought my VX the mileage was down to 12.5. I took it to the dealer for the 45,000 service and they did the EGR/PVC service but also cleaned the fuel injection. The mileage jumped almost 2mpg. When they switched our fuel here to the summer blends (less ethanol) it jumped almost another 2 mpg. I got rid of a Honda Accord with 22mpg for this, but I love it.
