I combust way more diesel than anything else actually, running 2 large frame farm tractors and a diesel pickup truck and in reality, I've had zero issues with the gummit mandated ULSD diesel fuel (Ultra Low Sulfur Diesel). I read online (of course) horror stories about how it screws up conventional high pressure injection pumps and erodes injector pintles and candidly, I've not experienced any of that. I do add a certified Biocide to my fuel (in my case Powerservice Bio-Kleen) because domestic refiners do add a percentage of bio-diesel to the ULSD at the refinery, I presume to add some lubricity (that ULSD lacks), before they sell it to retailers.Slightly off topic but I'm regularly surprised at the talk of the poor quality of the fuel available in North America. Does that apply to Deisel as well?
I suppose it must be due to refinery standards legislated by govts.?
For many years I never used stabil or similar although I do now. And not many average blokes I know ever use it. I have never seen canned fuel, but it is probably available in the cities.
Hardly any E10 is sold of course.
Some Aussies will probably chime in now with horror stories, maybe I've just been lucky with pump 98 and premium Deisel
The issue is, Bio-Diesel is notorious for growing algae and having been down the algae road once before, I don't want a repeat performance. Not the algae itself that destroys injection systems, but the exoskeletons that destroy high pressure injection systems like injection pumps and injector pintles (the moving part in a high pressure diesel injector).
I went through that scenario a few years back and it cost me over a grand in parts alone and I did all the grunt work myself. New injectors, new lift pump, new filters, associated piping.. not ever again so to not have that, I added Racor fuel polishing filters between the fuel tanks and the first primary filters. The Racor's will strip out 100% of any contaminants as well as any water and they continuously filter down to 5 microns. Since installing the Racor's, I've had zero issues with fuel and that has been over 2 years ago now. If anyone wants to know the particulars, you can PM me and I'll give you the part numbers for the filter bases as well as the spin on filter part numbers and in reality, installing them is very easy and on the bottom of the spin on filters, each have a clear bowl with a drain so you can easily see what the filters are stripping out of the incoming fuel and drain it off easily.
Have them on my diesel farm tractors as well as my diesel pickup truck and one on my diesel bulk tank (500 gallon) just to make sure that I have no issues ever again. My diesel powered standby genset draws it's fuel directly from my bulk tank and I don't want issues with that either.
I summation, I have no issues with ULSD other than the potential growth of algae which I mitigate now. My tractors are all pre-4 units with conventional (Bosch style) high pressure injection pumps and conventional mechanical injectors as is my pickup truck and so is my standby genset which has a John Deere conventionally injected turbo diesel engine in it.
In reality, the Racor's are a cheap date compared to having to replace injection pumps and injectors and disposing of tainted fuel and cleaning out storage tanks and fuel tanks on equipment.
Marine operators have been Racor filtering units for years now to 'polish' incoming fuel prior to engine mounted filter units. Every big ship that is diesel powered have them as well as diesel powered pleasure boats as well. While physically larger (and more expensive) that what I use because their fuel flow is much greater, they work and work very well.
Finally, with the advent of Post 4 ECM controlled common rail injection systems, many OEM's are installing them or a similar unit on their engines. Kubota is one, Kubota is using a 10 micron pre filter on all their common rail diesels now, in addition to the normal pre spin on filter and sediment bowl.
