  • Stats: DPF 0 - 180,000Kms plus Fuel Economy, 2018 GXL

    2018 GXL Prado:
    ECU firmware updated early 2019. Both Custom Modes enabled. New DPF installed at 80,000 service (didn't need it, but got it anyway plus 10 year unconditional warranty). Kerb Mass = 2,740Kg+, GVM Upgrade 3,500Kg.

    Notes:
    a. trips < 5-8Km won't produce the conditions for DPF to start a burn in winter. This is how long it takes to warm the engine to start/resume a regen.
    b. 2019 ECU update significantly reduced the Kms between regens at highway speeds, and significantly reduced the time to complete a regen.
    c. DPF burn quits at 8%, the residual energy carries the burn to 6%, and at times 4%, 2% or 0%.

    DPF Manual button has Custom Mode enabled, used 11 times so far.

    Great info. DPF activities very similar to my 2016 except for custom mode 2. Despite 4 attempts they could never get it to work but at least custom mode 1(the light) works fine. My scangauge figures for dpf align with yours.. My lifetime fuel consumption is a about 11.5 but includes more desert than you as well as maybe 10000+ towing a 1 ton camper..Interestingly at 87000 km fuel consumption is improving. My outer southern edge of Sydney has improved from about 11.5 to 10.5 for the same sort of running.

      Ty 404pug.
      Given that I don't tow, my primary drivers of fuel consumption are:

      1. Tyres - my Toyo RT 265/70R17 guzzle a minimum of 1.5ltr/100 more than Dunlop AT 20 265/65R17, tyre pressures matter also.
      2. Speed - aerodynamic drag grows with the square of air speed (not ground speed). Headwinds increase airspeed. Add another 1-2ltr/100.
      3. Terrain - hills vs flat.
      4. Surface texture - bitumax vs rough highway bitumen vs gravel roads vs soft sand.
      5. Frontal cross-section - gear on the roof rack increases drag.

      Weight hardly matters!

      Up to the Kimberley shortly and the Oombi & CSR tracks.
      Will have data for 0-200,000Km later this year.
      Thats about the nominal design life of the vehicle; and where the OEM's book maintenance ends.

        CSR is a great trip. Yep. All the outside crap like roof basket, 2nd spare, maxtracks, bull bar, snorkell, all terrain tyres( Cooper AT3 LT 265/65 x17), and sitting on 100-110 getting somewhere, often 4th gear to keep transmission temps down really chews up the juice as do east coast hills.
