    I use WMO exclusively for years now in all my mechanical diesels. Blend is 85%. Love it. In Northern Canada runs great in the winter at -40 no preheaters, same blend.

    In beginning had trouble due to not clean enough, plugged some injectors. invested in a bowl centrifuge and never looked back, fuge it, blend it, fuge it again. fug'ing at rate 5 days for 1000/L

    Am currently running a "destruction test" in my old test 470K 2008 Jeep Grand Cherokee with the Mercedes 3.0 CRD. at 3500 kms and no issues, took a few tanks for the computer to readjust in beginning smoked blue on idle like a bugger! only difference i see now is that I roll some coal when accelerating hard. Only mods is hot chipped from GDE, DPF delete and 1~mic absolute inline filter before factory filter. Also drive it like a stole it - but that is normal :)

    Am pretty optimistic at this point in the CRD test.

    To the pessimists - Yes I know wmo has sharp little carbon thingys and will wear injectors faster, that is what parts vehicles are for!

    All figures involve some rounding to make numbers easier.

    So 3500Km = ~2200miles
    17mpg (remember the drive it like you stole it)
    2200/17 = ~130 gallons used
    Canada - $4.58/gallon (1.20L) ( we carbon tax our fuel to save the environment!! - not sure how that works but been assured by my betters it does)
    I figure it costs me .20/L or .76/Gallon to make (paying myself $0.05L $0.19/Gallon for hauling/pumping oil, some capital costs included, trucking, centrifuge etc.. not free)
    I save 3.79/gallon
    So current savings 492.44 in the last 6 weeks. $82/week, $4264 a year

    Paid $3000 for the jeep. Current ~200K jeep CRD prices ~$7500

    If this works then I will pour it into my wife's nice, $16K, low mileage jeep and she does about double my mileage so $8528 a year savings in hers + 4264 savings in mine $12,792 savings in fuel a year for this family JUST in our daily drivers. Not including farm tractors.

    I can buy 1 "new" jeep every year if I have too and still be ahead...

    Am I willing to risk it? So far I think yes...

    Good stuff! Good to see it runs ok @ -40C. I've run into problems around -10C with my mix: 85% WMO, 10%RUG and 5% Biodiesel (for lubricity). It would appear that perhaps the biodiesel is causing the problems. I know it gels at -6C.

    Are your calcs using Imperial gallons or US gallons?
    Avoid confusion, use Metric units. ;PokeLOL:angel:

    There was alot of rounding in my conversion calcs, Her majesty would be disappointed in me as I used US gallons from those ungrateful colonies :)

    Why would you use biodiesel for lubricity? lots of guys add some atf to their regular diesel for lubricity and we are running 85% old oil - lots of lubricity! Even some nice carbon chunks to cut polish the internals :)

    Jeep is in getting a new set of glow plugs right now (I am lazy) and the mech is going to take a peek with his fibre camera and see how bad the coking is. I am quite interested in the results.

    Might start running a can of Sea Foam through every 5 tanks or so.

    Pretty impressed how the ECM is adjusting for the wmo, smoked like a bugger when I started - now only rolling some coal on acceleration and that seems to be decreasing as well.
