Fuel Consumption - Towing

XTZ,
You don't mean kms/litre do you? Those figures seem unreal for litres/100kms.
Stephen.

I think I must be back to front 530 kays = 60 litres ( 530/60=8.83)
8.8 k's per litre. (I think) on hwy
My Jack has just turned over 60 000.
I am just getting used to km/litres
Instead of mpg. I trust someone will tell me if I am wrong.
Sorry if I have stuffed it up it wasn't on purpose, am I right or wrong and are these good figures.
XTZ

I'm a mathematical whiz, how does 11.3 litre's per 100 km's sound.
You were right I get 8.8 km's per litre.
I admit my mistakes for all to see.

regards XTZ.

Its fools like you that cause accidents, as far as I know towing at that speed with a 18 ft boat is illegal, suggest you let your mother drive her own vehicle before you wreck it. Regards.

Chris,
IT IS NOT ILLEGAL IN SA. In SA you are allowed to tow at what the speed limit is, so I do, and do it safely. If I didn't think it was safe (or foolish as you put it) I wouldn't do it.
The whole rig is perfectly balanced, the trailer is braked, controlled by the towing vehicle. The next size boat up from my hull, the 20' comes in at less than 2.0T, so can still be towed at sign posted limit.
The Jack has no problem towing this weight at sustained speeds as indicated.
Suggest a little research (ie put brain into gear before engaging mouth {fingers and keyboard}) would have been helpful here in your follow up.

Cheers,

Dion.

Normally the boat is towed with my Rodeo, and the Jack only used if more than two of us go fishing.

From the Transport SA website.
Vehicles towing a trailer with a GCM of less than 5.0T may tow at the posted speed limit.
Naturally a trailer with a GVM in excess of 750kg must have brakes and trailers with GVM in excess must have atomatic break away system.

Cheers,

Dion.

Chris,
thanks for your responce. I have driven towing trailers, including the boat ever since I could drive. Where you raised my hackles was reference to letting Mum drive her Jack. Sort of fealt like you were talking down to me like I was a kid just got my license. Now well into my thirties, I have been driving for over half my life.
I do when I need to slow down, as required to suit conditions.
I have also driven briefly semi's, triples and doubles in SA and NT so I have an appreciation of MC vehicles. I'm the guy that hangs back and gives a semi the room to manouvre, not like some other city drivers. I could create some controversy and discussion here and suggest that anybody going for there license during the learner stage (cars) should ride with a truck driver to gain appreciation of what a truck driver has to put up with all the rest of us 'smallies' on the road.
Looking back at original post, boat on trailer weighs 1.80T, not 1.89T, (zero and nine too close together). Towing with the auto Jack, third is harsh (indecisive) with the gears, D is better, however find it is kinder on the gearbox as the Jack (with boat) slows, to ease off on the accelerator and keep the box in OD. Stops the hunting of the box. Also the hilly sections of road I were refering too between Port Augusta and Poochera where I turn off to Smoky Bay are straight hills, not twisty windy stuff.

Cheers,

Dion.
