Thread: Patrol 4.2tdi fuel usage.

The 4.2 just craves a small turbo running 3-4 psi

A low boost setup sharpens throttle response, increase HP and torque, and improve fuel economy

Well done on papers,im a broken old carpenter.I payed a diesel out fit in Timaru to check out the turbo.Thats the result they gave me,they called it a lazy old motor with a low turbo factory setting.

Maybe he was just a slow learner.

Not an economical way to drive at a set limit either because no coast run over on down hills and up the other side and up it on any uphill to maintain 109

Nelson city to Hamner and back yesterday....speed limit set to 109kph and sat on that up hill down hill round corners plus a few flat to floor overtaking maneuvers and brake down to limit when back in lane.
Over 600km driving pretty hard...8.5l per hundy on the computer, and that is higher than actual usesage as running bigger tires so actually cover more kms than the computer thinks.
Real usage in the high 7s for driving like a rental.

Love how economical the Triton is.

I think @7mmsaum is refering to the old GQ's running no turbo. I do know a mate who turbo'd a SWB GQ and got low 30's mpg. (9?L/100km)

My old auto SWB bounced around between 12-13 L/100. That had KL71 muds on it. Tyre pressures made a big difference.

Mines a big turbo running 30psi lol

Mine was non turbo but one of the black top high torque donks. That thing wasn't the crispest on response but stump pulling torque. It was hard on mounts and clutches!

Beauty and the Beast in one.

1997 swb gq. 2 inch lift 33s roof rack. Factory turbo engine, running hx30 20psi top mount cooler, tuned pump putting out 185hp and about 470 NM. Can get 700kms from 70l on the regular driving from masterton to wanaka. Not too bad a for a old brick.
