Is 240000 miles bad on a f250 diesel

Is 240000 miles bad on a f250 diesel

not if oil and filter changes were made on time...the amount of "smokin'" will tell the efficiency~ the compression could be checked against the charts as well~

timing chain stretch is always a consideration...you can look at the timing chain tensioner to see if any more travel is available and perhaps change the timing chain for added mileage~

What year is the truck? The 7.3 6.0 6.4 and 6.7 motors dont have timing chains they are all gear drivin. So there is nothing to worry about there. 240000 is nothing on a diesel as long as it was well maintained.

The amount of somking does tell you anything about efficiency. Diesels somke thats what they do they produce soot. The new ones have had lots of changes to the exhaust and other systems to prevent smoke for emmisions reasons. But you take all that emmisions crap off and any truck will leave a blak cloud when you get on it. Especially ones that have been chipped to up performance. Ones at drag stips smoke like trains and there making 800 horsepower and well into the thousand ft/lb torque range which is plenty efficient.

Is 177,840 miles a lot for a 2011 ford supper duty f250 desiel
