I get about 16 mpg (US) trail riding with my Bearcat 660 turbo. And it's a hog of a sled size and weight wise. With a full tank it weighs in at 840 lbs plus my 200lbs plus the occasional passenger (or two).

Would like to know what miles per gallon most owners get with 660st and other turbo 660 cats. On the last ride, I was using about 95% as much fuel as the new f8 I was riding with. Both were riding about the same speed and driving easy on trails. I thought I would get better than the 15mpg I was getting. I am talking about the (larger) canadian gallon here. If replying, please specify canadian or american gallon. I only recently got this sled, and heard they were economical. Thanks...Bruce[/b]

I have an 05 T660 turbo and we get about 17 to 19 mpg when doing normal trail riding. Push it hard and it's is 15 - 16 mpg.

 

I get the same thing as phj. Snow conditions will also help or hurt you millage.

My wife's non-turbo get a mile more better them me pretty consistently.

My best was 22.7 and worst was 14-15 (towing another sled) mpg imperial gallons.
This engine is very sensitive, the more you are into the turbo the more gas you burn.

 

Pretty sure i'm averaging 19-20 mi/gal Cdn on the T660 T.T
but at 1000Km , i'm just past break in . I only 2-up with my wife so between us thats 325 lbs
Last trip we drove 198km of winding trails and 4-5 long ,high speed lake runs had 1/4 tank left .used 29L of gas . it might be me or just different riding conditions like Kopeck states but i swear i've been getting a little better milage with midgrade vs Regular .

 

I'm getting between 15 to 19 mpg with my 2006 T660 Bearcat! Depends on weather, weight on sled, and driving!

 

I rode 575 miles last weekend with my 2005 st and averaged 17.96 MPG american. Rididng in the U.P. of Michigan at speeds between 55 & 30, with an occasional squirt up higher. Riding with a 570 Z I was useing about 3.5 gallons less on a fuel stop, I weigh about 100lbs more than the rider on the Z. I was very happy with the fuel MPG & I didn't use any oil either, compared to the 3.5 Qts he used. Going back up this weekend riding with 7 other sleds & different makes.

 

had an 05 T660 Turbo Touring...with me on it average 20 MPG (US) at an average rate of speed of 35 MPH...I weigh in at 185lbs...with the wife on it same speed range, she doesn't gun it to get there though, 23-25 MPG (US) and she weighs around 130lbs...if you goose it you will get less mileage...sold the sled with 3400 miles on her and still running strong
