  • The 1KZs of that era were still 4-speed.

        HNL is the rear airbag height adjustment setting. Not the gearbox.

        • Progress, it's 05 registered not 05 build.
          So it's an 04 4 speed, Andrew you were correct again.
          I really think it has increase fuel capacity, will find out just how much when he gets a loan to fill it

          • Just to add.

            our v6 as it stands is an amazing motor.
            Alot of power and over taking capability.
            Towing is amazingly efficient too.
            180kw and 364nm of torque

            The torque comes in nice and low in the rpm range too.

            Factor this in with the engine pulling close to 2.3 tonnes of metal

            You use around 14litres per hundred around town and 11.9 on the highway.

            Its pretty amazing.

            1kzte arent much better on fuel either. (cracked heads) I have owned two and both cracked on me. Not a matter of "If" but a matter of "when"
            1kd yes but you know the deal there. Boom.


            Nissan patrol 4.2 litre diesels drink about 16l per hundred around town
            Nissan patrol 3.0 litre diesel drink around 14 to 15 around town too.
            They both carry 3 tonne bodies around.


            the 1GRFE motor is great and reliable too.

            Just putting it out there if anyone is feeling bad about their fuel consumption.
            Okay its never under 10 litres per 100 but put things into perspective and you realise how good our petrol prados are.

            -Get a scangauge and watch your driving habits.
            -Keep your tyres around 40psi or more.
            -Dont get LT tyres and over sized tyres if you dont need too.
            -Warm her up so the ECU is out of closed loop and not running rich in the morning.
            -If your kms are abit high. I suggest changing all 4 oxygen/af sensors. They dont have to throw a code for you to change them. They get old and start to operate out of range. The ECU compensates by running a tad rich to protect the motors.





            Here is a insert from a tunning guy testing a stock 2uzfe in the american Prado (lexus GX470) vs a stock 1grfe v6 . Surprisingly we make 78 percent of our max torque as low as 1000rpm and continues to spread it across nicely. Yes. The v6 is a good low end performer. Maybe it explains why it tows so well and efficiently for a petrol.



            "4.0 V6 1GR-FE approximate torque % (torque at specific RPM divided by max torque):

            Max Torque listed is 282 ft/lbs at 3800 rpms

            1000 rpm = 220 ft/lbs over 282 ft/lbs = 78% of max torque
            2000 rpm = 250/282 = 88.6%
            3000 rpm = 260/282 = 92.8%
            4000 rpm = 275/282 = 97.5%
            5000 rpm = 255/282 = 90.4%

            ----------------------------------------------------------------------
            4.7L V8 2UZ-FE:

            Max Torque listed is 320 ft/lbs at 3400 rpms

            1000 rpm = 270/320 = 84.4%
            2000 rpm = 285/320 = 89.1%
            3000 rpm = 310/320 = 96.8%
            4000 rpm = 290/320 = 90.6%
            5000 rpm = 230/320 = 71.9%

            ----------------------------------------------------------------------
            Conclusion: from my point of view, the V8 engine (non-VVTi) definitely is designed for low end power...the torque curve clearly favors low rpm torque over high rpm power. The V6, on the other hand, is a more modern design with VVTi...and this VVTi technology is clearly reflected in its flatter torque curve (shocking finding for me!). The 4.7L V8 gives you a lot of torque early, but falls pretty quickly after it peaks at 3400 rpm.

            The V6 clearly cannot match the V8's low end torque production...because there is "no replacement for displacement." That much is true. However, the V6 numbers are far from being peaky nor anemic...it produces a respectable 78% of its max torque as low as 1000 rpm...and jumps up to 88.6% (matching the V8!) at 2000 rpm. What is nice is that the torque stays there after it peaks at 3800 rpm...all the way till 5000 rpm (90.4%)...you can thank VVTi for that!

            What does this mean? I have no idea. You guys can come to your own conclusion. Many will argue that the V8 produces power where a truck needs it the most...and where off-roading needs it the most. Others will argue that the V6 is fully competent in the lower end, yet still provides excellent response at higher rpms. Your miles may vary....

            NOTE: in 2005, Toyota added VVTi to the 4.7L V8 engine...unfortunately, i do not have the torque curve for that engine. I am sure that VVTi would improve the 4.7L V8 engine torque curve at higher rpms, thus making it as flat as the V6's curve.

            • I just filled up as premium was $1.53.

              Odometer showed 930kms from previous fill. It took 148 litres.

              If I have done my sums right that works out at 15.9litres per 100kms or 6.3kms per litre.

              Driving is all around Sydney Town, commuting, etc but not in normal morning or evening peak hours.

              From the the figures I have seen quoted from others that seems about as good as it gets.

                So you zeroed the trip meter at the last fill and have driven 930kms since? Did it take 148 litres this time or last? Just trying to work your formula out. I've never tried to work my fuel consumption out properly but need to fill up, seems a good opportunity. I am guilty of using 91 unleaded because of the discount dockets would be interesting to establish if there is any noticeable improvement in fuel economy by using 95/98 instead.

                • Fido, I presuming to get the figures he did this. He started off with full tanks, and trip meter reset to zero. Since then he has done 930klms showing on trip meter of running around then has refuelled both tanks putting in 148 Litres of fuel. The sums are, 148 (Litres) divided by 930 (klms) x by 100= 15.9L per 100klms.. Great going for around town.......Cheers Steve

                    Steve, Fido - thats exactly correct. Apologies if I didn't set that out properly. (I know what I was talking about!)

                    I have just added a custom made rear bar/wheel carrier and Hayman Reece towbar. Both are bloody heavy so it will be interesting to see if the extra weight has any effect on fuel consumption.

                    • 2009 GLX auto with 58,000km. Average consumption around suburbans of Brisbane is 13.8L/100km. Calculated in spreadsheet over about 3000km travel. Car is running on stock tyres without roof racks and any modification.

                      In the future, I would like add nudge bar for driving lights and dual battery system (prefer the light weight Lithium ion battery).

                      • My best ever fuel figures to date - maybe the 170,000kms has triggered an improvement......

                        Travelled 1086kms from 159.59L = 14.7L/100. Did about 250kms with 1.5t camper trailer on (hwy) and general mix for the rest. Pretty happy with results. No change in driving style that I noticed.

                        Doing a brisbane Sydney brisbane road trip next week so will measure it out.

                          • has there been an update on australia's most fuel efficient prado? Interested to know how he is getting that sort of economy.

                            • Just completed a brisbane to port Macquarie return journey (approx 1150kms) and recorded results.

                              Trip down - 13.66lph
                              Trip back (towing jayco camper trailer) - 19.13lph

                              Very happy with figures.
