kilo6 Posted March 13, 2010 Share Posted March 13, 2010 hi boyko i have a cxn613 13 spd and 3.86 rears with an AC427 hp motor tractor otr with a 53 van. not the best fuel mileage from this yet, i get approx 6mpg average for the month. i do notice mpg has risen with outside temp rise. i usually drive about 63 mph. i will be interested to see what the pros say about mpg here as i feel this is an area that will be more relevant in the coming months. This also has a bearing on mack otr sales. i wonder how is the 2010 pinnacle doing mpg wise??. By the way i love my mack it is so much more solid than my old century, no comparison.

JerryB Posted March 14, 2010 Share Posted March 14, 2010 I have an 04 Vision with 460 that gets 5.8 to 6.2 grossed out at 79,500 to 80,000 and abiding by speed limits. If I run above 1500-1550 rpm it drops down to 5 mpg or less. Quote Link to comment Share on other sites More sharing options...

Greg Rider Posted May 9, 2010 Share Posted May 9, 2010 Operating the truck at anything above curb idle significantly increases fuel consumption from my observations.RobYes I'm still here. If my memory serves me correct, Rob should not be giving advice on anything fuel related as he forgets to put fuel in. Seriously though, start with the stupid stuff like air filters,clean injectors,and possibly a better exhaust. Anything that helps the engine breath will benefit. I have found out with my car that if it stays under 70mph the milage goes up a lot on the highway. it may be something that simple that gains a noticeable amount.

vision386 Posted May 9, 2010 Share Posted May 9, 2010 HI I HAVE A MACK 460 VISION,THE MPG IS 4,5.DOES ANYBODY KNOW HOW I CAN GET BETTER FUEL MILEAGE?You should be able to do much better than that,i also run a 01' CX-613,E-7 460, i get considerably better mpg's but, the freight i haul is relatively lightweight. you did'nt mention what you haul,weight ,areas traveled etc. there are many things you can do to improve mpg, but as already stated, start with the basics.......mark Quote Mack Truck literate.
