Hell of a good “service” if you dont have to tilt the cab or does this model not have driive belt tensioners,coolant pipes,oil feeds you need to check?
And next time I see a "spun "main bearing shell that needs either a crank grind or worse a new block I can tell the gaffer “dont worry at least it didnt sieze”
He will “love” that !!!

you only mentioned the oil filter, not the service, the oil filter is usually done from underneath, drop the oil, change the filter, then refill the oil, all with the cab down, when the oil is up to level, fire the engine up and let it idle for a few minutes, then turn it off, when the oil level has settled, top up as necessary, then tilt the cab to do the rest
where is the problem?
The original post said the vehicle was in for a “service” not an inspection.
You can’t change the oil filter on a merc 2546 from the underneath and im sure scania is the same.

How long have you got between losing the oil and it seizing? My Vauxhall drinks oil due to the ragging it got from its, ahem previous () owners, the 'stick can be dry but still the oil pressure light won’t come on… (The bulb does work).
I read in Ride magazine several years ago about a bloke who was riding a bike when the pressure light suddenly came on. Unbeknown to him the oil had been draining out steadily. He whipped the clutch in, coasted to the kerb and killed the engine but the engine was [zb]'d.
The time between the light coming on and stopping the bike was only a say 20 seconds I would think but it was enough to kill the engine.
the oil pressure switches on cars are set that low that by the time the light comes on its too late always replace mine with a higher pressure switch from a motorsport catalouge given earlier warning for the couple of extra quid it costs well worth it .
or fit a pressure gauge

Swings and roundabouts really though, some trucks have a filler and dipstick under the grill others you’ve got to tilt the cab. Personally I probably wouldn’t if I knew I could get to what I need without. I think BKing works on Tesco trucks or something like that as he talks about everything relative to Mercs.
Driveroneuk:
Electrics probably will not actually stop the engine. If sensing a lack of oil may put it into reduced power mode and put the red STOP light on, on the dash. If you are not sitting in the truck, obviously no warnings would be seen.Its not a large workshop, I think there’s only 2 of them, so signs etc. aren’t needed as each knows what the other is up to and an in any case one works on units, the other on trailers.
When I was running my (non HGV) garage business I always used to take the keys out when I’d dropped oil … and there was only me there!
In this case it was up to the tyre fitter to ensure it was safe to start the truck.
If I was running the workshop I would still view the fitter most negligent for leaving the keys in. I think you’ve got some very ambitious ideas of tyre fitter general competence. Personally, I’d be very reluctant to let tyre fitters anywhere near one of my trucks outside an emergency, tyres aren’t my favourite job but I’d rather do them myself than let a tyre fitter dent and scrape the rims the over-torque the nuts with an air wrench.
On a recent inspection on my truck
The fitter jack the rear axle up to remove the rear wheels off to check the brake pads. He didnt drop the mid lift down after a couple of swift hits with a sledge hammer the rear of my Daf fell off the jack into the pit . Que lots of panic and the use of a overhead crane to remove it from the pit anybody what to guess who got the blame Yep me !!
For the few seconds it takes to chock wheels I always would even if I was jacking the steer. You never know if, unbeknownst to you, someone else has decided to wind the chambers on the drive axle off.

Me? Nay lad, it were nowt to do wi’ me. Don’t shoot the messenger, I merely relayed the tale.
Ok cowboys “technically” you dont need to tilt the cab but unfortunately “I” give a ■■■■■ about my professional competence in what I do in my work.
It takes 5 minutes to raise and tilt a cab and,even just to check a for a coolant leak or a ruubbed through air pipe,if it saves a recovery,a siezed donkey,or even some bugger not getting home on a Friday nite to give his wife a good tommin instead of sittining at Frankley services then I feel I have done my “job”
I am a professional and I do my job to the best of my abilities.
