I checked my injectors in the truck today, and they are all breaking at 1500 PSI, with only one not really fogging as it sprays. But get this: with only 200 kms on them since I mixed permatran with diesel in a 40/60 mix (60 diesel), the injectors were beginning to coke at the nozzles! It wasn't to the point of power loss, but it was heading there. All I can figure is 1) the coking happens when the engine is cold, as it starts and runs fine on this mixture hot or cold, and the combustion chamber isn't up to operating temp, not allowing the oil to get hot enough to completely burn off, or 2) there is no way in h*** I can run this stuff no matter what. When I took the injectors out, the engine was at operating temp so they were hot, at least warm enough to need a rag to hang on to them, which is going to warm the fuel to the same temp before injection, since fuel isn't flowing through the nozzles like a fire hose. I have a feeling it's going to be #2. Waste oil furnaces have a very similar build-up, and they run hot for hours. I used to run the old style furnace for years, and often had to use a hammer and chisel to clean the fire tray and nozzle. Same color and texture of build-up. I could watch the fire in the furnace through a view port, and the build-up wasn't formed at the beginning. I have to make a run in a couple of weekends (200 mikes or so), mostly highway, so I'll use what's left of the mixture then, waiting until the motor is up to temps.

Next I'll try new canola as it's not much more than diesel now. Ambient temps here are still high enough to try this with un-heated lines. Diesel here at one garage I bought furnace oil at (for the Kubota) was $1.179 a liter, full serve. Furnace oil was $0.989c/l. When will the madness stop!?! <img src="/forums/images/graemlins/zombie.gif" alt="" />
