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 ******! 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 ****** when I started - now only rolling some coal on acceleration and that seems to be decreasing as well.

Update - so ran about 7K so far and all is good - except one small issue. I wont start worth a crap on straight W85 tip start takes 3 trys, so switched to reg diesel and problem went away instantly.

Working on blending w85 with diesel and see how little I can use before starting gets bad. Also going to setup my glow plugs on a pushbutton and see if running longer works.

thx JJ

I should have said I add biodiesel as a cetane enhancer, as well.

I normally add 2 liters to my rear tank of #2 diesel for lubricity & cetane booster.

This last weekend I took a 780 km trip using a blend of:
75% WMO
11% RUG
4% Biodiesel
10% Diesel

The 7.3 PSD ran great!
