    Default Land Cruiser 4.5 V8 diesel consumption

    I have a 2018 Land Cruiser bakkie, 4.5 V8 diesel.
    It is gobbling diesel!
    I have had 2 x 4.2 diesel bakkies and about 7.3 km per liter (farm work and occasionally to town)
    1 x 4.? petrol (about 1990 model) and it did between 3 and 5 km per liter, It dam near bankrupted me.
    In November 2019 I towed a small caravan (Sprite Tourer SW) to Namibia and back, 6341 km. About 5.6 km to the liter, doing a sedate 100 to 120 km per hour. I can live with this consumption.
    In March 2020 I was back in Namibia, canopy not laden to heavy and 120 to 130 km per hr, call it 6.1 km per liter!! over the 5111 km.
    The bakkie is relatively new, currently on 32000km.
    Now, my question,
    1) remove the cat?, can I expect gains? (DIY job)
    2) Fit a de Graaf exhaust?, can I expect gains? (fitted here in the EC about R9500)
    I include my log book and a few photos.

    Take out the cat and do a proper downpipe. Yes a big exhaust is nice, but not really necessary.

    Then get somebody to optimally map the ECU. No fancy performance tuning.

    Mine is a 2015 with 75 000. Bigger pipe, new snorkel head and chipped. Still hell heavy. Was towing a 4m cattle trailer @ 120 km/h empty to Swakopmund ( 380 km) one tank mo#@toe = 85l
    Took it a little easier back , fully loaded = 76l gone
    On the farm I get about 7,5 km/l , but speed is killing consumption.

    yep

    120-130km/h will suck diesel like no tomorrow

    Pretty normal consumption I think.

    I get 6.5 km/lt traveling unladen/laden at 100 km/hr
    5 - 5.5 km/lt when towing.

    Ons het al baie V8's se rattekaste ge- upgrade na die langer 2de en 5de ratte wat die rpm ongeveer met 500 rpm laat val afhangende van buiteband groote .
    Ons self het nog nooit brandstofverbruik getoets nie maar baie kliŽnte sÍ terugvoer was daar is 'n verbetering van tot 1.5 kmpl .
    Met die modifikasie kry jy 50kmph vir elke 1000 rpm

    So dit sal beteken

    1000 rpm = 50 km/hr
    2000 rpm = 100 km/hr
    2500 rpm = 125 km/hr
    3000 rpm = 150 km/hr
    3500 rpm = 175 km/hr

    Cat is out, 1.5 hr job, I could be prejudge, it fells if it is pulling better. time will tell! (looking at the cat and what has come out, it must restrict exhaust flow)

    There are two cats in the system. One at the turbo and one further down. The cats on my 76 were almost blocked at around 40k km.

    Install a De Graaf. Then take it to a Toyota dealer to upgrade the software. Look out for a youngster.Toyota have some very cluedup
    young technicians that are very helpful.

    I cannot speak of the 79 v8 but on the 76 v8 I average around 7.6 at 120 even with stuff on the roof rack. Hard to explain why but in real careful driving doing 120 I got around 8.2km/l on 50ppm fuel. Why I don`t know but all my plus 8km/l runs were on 50ppm.

    Something to keep in mind is that the oddo meter of the v8 Cruiser under read. Depending on tyre size I have checked mine against the GPS it under reads by 5 km per 100km. Makes quite a difference in consumption calculations.

    At those consumption levels you may as well get an LT1 conversion.............

    I hear you Jelo. I've recently been toying with the idea to swop my trusty diesel steed for a big capacity petrol. I came across a towing comparison of the facelift 2020 Patrol V8 petrol and the LC200 V8 diesel. The Patrol was actually ever so slightly lighter on fuel than the 200 with a 2 ton off-road caravan in tow (not an off-road tiwing test).

    But the Patrol drop to 30l/100km in serious offroading. There is no way you make 300kw at economic rates. I come a long way with v8`s.

    Run the same test over 1000km. No v8 normal aspirated petrol will ever equal turbo v8 diesel consumption. No v8 normal aspirated v8 can change the laws of physics. You need energy to make 300kw like in the case of the Patrol.

    I know a guy from Prieska with an LS conversion 5.0km/l at 120 if you are lucky. 2.4km/l when you play and 3.5 to 4.0km/l when you tow at 110km/h. 260kw does not comes for free

    Think all the guys that get less than 7.0km/l @120km/h have had them chipped.

    I won't ever dispute that. I just found it interesting that the Patrol was lighter on Petrol than the 200 while towing up and down a mountain.

    I like the Fuelly app and went to have a look at what you can expect over longer periods of ownership. I randomly chose two candidates with good average plots (not a lot of outliers) 5.7 Petrol 200 and a 4.5 Diesel 200. The petrol averaged 6.0 and the diesel 7.2. About a 20% penalty for every day use.
