CAT 450HP engine fuel mileage
I have a friend that claims he gets 10.5 MPG at 75 mph in his 2001 450HP Cat 40Ft beaver PT motorhome and his average is 9.5?? I only get 7.5 in my ISL425 and I only drive 63MPH ? Is this believable...

Is this believable or?
Hes pretty smart guy about facts and figures?
Your friend is stretching the truth a bit I think. My equipment is almost identical to your friends except I bet his weighs 5K more. I can return slightly over 10 all day long every day if I limit speed to 55-60. Done that over thousands of miles. At 75 I'll be 8.5.
ok so he says 9.8 average and u say 10 all day long so whos stretching the truth then?
Not to quibble but I can only achieve slightly over 10 by driving 55-60. Your friend is able to make 10.5 mpg driving 75. Big difference. He must have air tabs. ;)
