ave gas milage question

[TroyRXP15]

OK I am planing a trip up the lake champlane canal labor day weekend. I just want to know how much gas I am prob going to need. Also how long a tank will last me. Any input would be great.

The other day I got 72 miles out of the tank. Could have probably made another 4 miles but would have run out of gas. Was mostly riding in the 4K-6K range for that tank. Hope that helps. You may want to put a 2 gallon can in the front bucket if needed

thanks for the info I know there is an area on the canal that is like 10mph I am thinking that I am going to have my friend tow me on the boat for that because it is going to suck.

can you run Av gas in the Rxp's?

[Thomas]

I suppose you could, but there is absolutely no benifit to it over a good quality 91 octane. There also might be some additives in AV gas that would not be good (not sure, but I remember hearing something about that).

If your friend tows you remember to pinch off your cooling water intake hose.

I have got 100 miles on a tank a couple of times.

Gas mileage always depends on your speed.

What are the disadvantages of running 87 & 89 octane in my '05 RXP instead of 91+?

[Lurker]

decreased performance. The motor will be a knocking and the computer will retard timing (less performance) so your motor doesn't explode with the lower octane.

Also AV fuel is usually leaded and full of aditives. I know on cars using AV fuel will kill the o2 sensor and cat. Since I'm new to these beasts I have no idea if they have an o2 sensor to kill.

u can run a mildly modded rxp at WOT for @ 2 hours
