Hilux engine revs

Hi Rob,
Is your truck diesel or petrol?

Moz

The big engine and large torque in my falcon allows it to be geared at 2000 revs at 110kph and bolt like a horse when planting boot but the old petrol hilux is another story, around 3000 revs at 100 and bolts like a slug.

rule of thumb is "two thirds of your redline is the maxium cruising rev speed" whats your red line 5 grand?

My petrol 4 cylinder Rodeo sits on 3000 RPM at 110 km/h.

My diesel 4 cyl na Navara about 3200 rpm = 110km/h Redlines at 4700 rpm. I reckon 90% of my driving is done beteween 2500 and 300o revs.

Pembo, think of it all in an engine design timeline. Early diesels has much lower engine red lines and the technology is not what it is today. Some were most effective at 1600 revs and started to come apart at 2000 revs. Some of course would not make the 1600 revs in earlier days.

Modern ones with better montoring and fuel metering are much closer to rev ranges of petrol motors, but better torque ranges with good design. Just think the 2.7 litre Mercedes diesel motor against the 4.3 litre petrol - the torque is well up at around 390-400 Nm for each but fuel usage well down on the oiler.

Your neighbour is thinking old technology but some can really do it still. Just remembering the new Rover 2 litre which is showing up in road tests now. I drove one a few hundred miles last year. 90 miles an hour up hill and accelerating strongly. I loved it - but it would rev well too

Gday Rob,
I have a 2000 Hilux Dcab 3 Litre Diesel and it sits on 3000rpm at 105 - 110kph. I think I found in the Gregory’s manual that the max torque is generated at 2600 rpm which = about 90kph and from what I’ve read, other Hilux owners get their best fuel econ at this speed, from memory I think redline on mine is 4500 – 5000. So I don’t think you have anything to worry about.
Hope this helps.
