Attn Hurryup&Wait.
I agree with you about Scania being good overall and in our area at least the dealer back up knocks spots off all others, they’re also in the top fuel figures and are good to drive to boot.
MAN are sorting their previous issues out (that EGR 440 engine) and yes they are underrated, in some cases drivers hate them purely due to the large steering wheel though clutch engagement and smooth take off with Arsetronic was a learned technique , early days yet with Traxon which is much improved.
Generally with fuel consumption, as i said before all the vehicles i’ve used on this job the fuel differences haven’t been enough to say one stands out more than all others, the most economical engine i found over the last 12 years was the 420 Scania (going to say euro 5 but don’t hold me to that, hmm probably euro 4 thinking about it) and yes i have seen a genuine 15mpg on one of those but on very light work (driven in manual and not over 1000rpm if anyone’s interested) and i was sad enough to take a pic of the dash
To put things in perspective, in the 80’s i used to average 7 to 7.5 mpg at 38 tons at a mean cruising speed of 70mph, on one economy run (again fairly light work and just to see what she could do to the gallon) with the same lorry running at 55mph i got just over 12mpg, so much for progress, but then that lorry was geared for 1100 rpm @ 70…and yes properly specced Brit motors knocked spots off the Swedes both for performance and fuel usage.
On transporters at the time, early to mid noughties we ran Volvo and Scania (mainly) 420’s, bear in mind these things tared off at 22 tons and lots of fast idle running the hydraulics sometimes for hours a day, the Volvos returned around 6mpg overall, the Scanias 7 to 7.5…sounds bad i know but car transporter work has always been fuel heavy, and seldom does it involves long distance trunking.
On my current work, which is tanker and full weight, a long easy motorway run might see the 10 to 10.5 (incl pressure tipping) Gingerfold mentions but i run at 52/53 mph and not just for fuel but mainly cos i can’t be arsed with all the pushing and shoving of the ‘‘on the limiter haven’t got a minute to bloody live crew’’, so by running at 52 they can all go by 10ft from the arse of the vehicle they are tailgating at any particular moment .
Other runs we do might be as low as 7 if it’s more local, so tipping time is a larger proportion of the fuel usage.
The driver makes all the difference, some drivers don’t give a toss and it’s foot to the floor all the way and on the throttle right up till the last second at junctions (so heavy brake and tyre wear too), their fuel consumption figures are bad, circa 2mpg+ heavier on many runs.
I’m not obsessed with idling as some trainers/managers seem to be, see i’d rather let the engine get a bit of warmth into it before asking it to work hard, and there is no way on earth i’m going to switch off an engine with red hot turbos.
Fuel wouldn’t be my only consideration when choosing a make, but if you asked me to choose an overall best bet make for good fuel usage good back up and a solid durable product that can stand some hard work, then Scania have it and by quite a margin, but that’s only my opinion and on the sort of work i do, a pure trunking job especially if not full weight then other makes might be better, horses for courses.
