I now run the same DSE 'Biodesel' in my 06 for alittle over a month now at approx. 50/60% veggy to #2 Diesel..
Well, the day after Thanksgiving I went to start my truck up in the morning after temps dipped into 50's & truck ran about 3 minutes or so at high idle(1200rpm with upfitter switch) & then engine died down & shut off! Im like WTF?:shrug: I had a strong inclination it was fuel issue. I check the filter on top of engine, no problem all clean, fuel level low. So I have my wife cycle key a couple of times & fuel rises. I then start truck, no problem. I say to myself, I better have a look at rail filter under truck. I shut her down & pull the rail filter & for the first time, I find the entire circumference of filter plugged solid with a tan like 'greasy' substance. I was pretty shocked to say the least as I filter the hell out of my waste oil!!
Im like, what happened here? Ive never encountered this issue as Ive 'filtered & blended' well over 250 gal or so of oil & NEVER EVER had this issue!:shrug:
I commence to cleaning filter, which btw cleaned real quick & easy with mineral spirits. I put filter back on & drive down the road a couple of miles & the engine starts to loose power & eventaully die! Now Im getting nervous. I pull to the side of road, remove rail filter again & find it clogged completely, yet again!
I wipe & 'sling' filter of what looks & feels to be like a 'wax' or gel/greasy substance :shrug: I put filter back in & start truck, which this time ran with a miss, which obviously was injector(s) not filled with fuel & 'dry firing' as I would describe it, which I know is no good for them!
So, I cycled engine on & off a minute or two until engine smoothed out. (I didnt want to damage injectors!) So, I drive truck back to my place & again pull rail filter & this time I saw about a 1/4 of the filter covered with grease. So, I clean it yet again & decided to drive it one more time about 6 miles total & if it was still clogged I would drain tank. Well, I made it back with no issues & I checked rail filter one more time & to my relief, NO MORE GREASE!!
Perfectly clean! :shrug: :Thumbup:
I guess, somehow, because of the low temps, some of the 'blended' fuel mustve gelled/congealed whatever? Now Ive been running an anti gelling additive from DSE, but maybe cause I was running a #2 mix with veggy oil, it wasnt enough? :shrug: It hasnt happened again since last week & Ive already added another 18gallons of 'veggy mix' to my tank & have had ZERO issues...albiet, no low outside temps!:shrug:
Sorry about the long rant, but I felt like sharing the experience
