    Wow that's no better than my 3.0ltr

      Just drove up from Perth to Geraldton sitting on 113km/h as per GPS and averaged 8.7l/100km. This is with 13000km on the ODO and 2 inch lift, on my own with tools and parts in the car. Tank was full when I left and did 438km and its just above the 3/4 on the needle. Scangauge gave me the 8.7l. The car gave 9.2. Thats not too shabby.

            9.2l/100km return but the car fuel trip reading said 10.6l. Will see what the calculation is when I refill before the end of the week. Toyota need to fix the 6th gear torque converter locking sensitivity. It was driving me nuts. Go up a hill torque converter unlocks and down the other side with it still unlocked and stayed that way for anywhere up to 2 mins on dead flat road. Painful

              Just filled the tank. Scangauge was out unfortunately ave usage 10.55l/100km. Not that great really. I do have to consider my petrol on the same trip would have got me about 15l/100km. I saved 5l per 100 so I guess not that bad really.

                  2.8 Diesel Manual Most Efficient Driving

                  I have just got back from a long weekend away, and was wondering about the driving technique for a manual to get the best fuel economy in the country.

                  I know the basic change up as quickly as possible to top gear and don’t accelerate/decelerate hard etc, but I am more thinking about when cruising at 100/110 km/hr (so around 2000 RPM in 6th) and you come to a long hill? Are you better labouring up in 6th, or changing down so the engine is at a more efficient point for the extra work? It is noticeable as the engine speed drops (say to 1800 RPM) the engine feels like it is labouring to the point you can start losing speed – and I assume become less efficient?

                  Is there a rev range it is best to keep the engine in? I had a quick search and found a power/torque curve for the 2.8 Diesel (note it is a GIF with the 2.4 also) – it shows torque pretty flat from 1500 to 2500 RPM.

                    Personally I would always err on the side of using more revs instead of lugging in a higher gear at lower revs for a couple of reasons:
                    1. Low revs with more fuel applied creates more soot, causing DPF to get clogged up more quickly, thereby requiring more burn off cycles later, which wastes fuel.
                    2. Low revs with more fuel applied creates higher EGTs (exhaust gas temp). High heat is an enemy.


                    By selecting a lower gear for hilly conditions, whether it's a manual like yours or auto for many others, the soot and temperature issues are better managed.

                    Sorry, didn't mean to divert from the topic of fuel economy but just wanting to give another perspective which should be considered, in the quest for best possible fuel economy.

                      just FWIW - drive Canberra to Brisbane today. 1300km's, computer says bang on 10.0L/100. I know it's not too accurate (but to be fair its only slightly off whenever I have checked it) but we all have one, so that's a comparison. Fitted with ARB Deluxe, IPF lights, Safari Snorkel, 2.1M platform backbone system and about 300kg's on board.

                        I just drove to Dwellingup and back and averaged 9l /100km. Car had 4 adults and 2 children. Sat on the speed limit all the way. Seems like DPF replacement has made a difference.

                          On my 2.8 GXL (just towbar and occasional bikes on a heavy towbar rack) it seems to have settled on: City=10, Longer runs=9. Hard to get below 9 (unless really trying) but also very rarely above 10.5. Seems to like a long run to 'clear it out'

                            Week old new GXL manual 2.8 and trip computer is showing 9.9l/100km avg after 450km. Semi rural driving, in hilly area.

                              I did a run this week from FSH (Fiona Stanley Hospital) to Welshpool and return. I reset the trip prior to leaving. Stopped a few times at lights but this was the true reading. I am currently at 1000km and needle has not reached a quarter. Trip meter says I still have 320km to go. I am seeing some very nice fuel figures this tank post new DPF. Usage increases as usual when accelerating but drops rapidly once cruising. Ive seen high 4's at 60km/h cruising. DPF burn has also changed. Sometimes the burn is above 300km whereas before it would burn 250km. Fuel usage during a burn is also lower from my observations.

                                Cuda, what prompted the DPF replacement?
