Depends on the work, if it's easy work even for the 7740 then I'd expect the tm to use more but if the 7740 is working near it's limit you might find the tm similar.So a tm150 wouldn’t use any more diesel than a 7740 in similar work
The TM probably isn’t the best example to use as although there a very good engine when working hard that 7.5 litre powerstar engine likes a drinkSo a tm150 wouldn’t use any more diesel than a 7740 in similar work

we could empty the fuel thimble in 7.5 hours drilling quite easily with our TM135 and 155 and although the T7.210 tank is only 18% bigger it will do 10 hours plus on the same job Easily
