who running on svo cooking oil?

Well just my thoughts on the matter, if you are running twin tanks, then you need to make sure the return goes to the correct tank, but also if you want to start on derv in the morning you will need to switch to derv a few minutes before you shut down for the night or your pump will be full of whatever it is in the second tank, I do not think I could be doing with all that messing around, Rick

All the more reason for bio
However there is a three way auto switching gizmo that does all that return to the right tank thing so no big deal really. Just remember as you say Rick to switch to diesel before bed

would running deisel one tank in 4 make some diference, help clean the inside?

hi well u dont have a return to the small tank in the boot when running on diesel the return gets looped back to the surply line then when u switch to veg oil it returns to the same tank it cam from as makeit fit says you just flick a switch 1-2miles before bed

u have to be care full as u have a heat exchanger on a single tank which means if u filled up with diesel, diesel would be going through the heat exchanger and u dont want to heat neat diesel up too much as it loses it lub propties and thats bad for the ip

Im not claiming to be 100% correct, farrrrrrrr from it.

The main advantage of a twin tank system seems to be that cold diesel, ie at the viscosity the engine is designed to run on, means smoother cold running. Makes sense.

Progressing that point though raises the question how can you replicate the viscosity of diesel with svo particularly from cold. The answer seems to be that different engines will tolerate different ranges of viscosity. The T2 seems pretty cool with a wide range so hot running isnt a problem.

However the logical answer to cold starting is either use diesel ie twin tank or heat the svo ie electric heater supported by a properly installed water heat exchanger.

I cannot find any evidence (including that flawed article) to demonstrate as opposed to express an opinion , that a twin tank will prevent gumming. It will no doubt be more efficient than a heater on its own for very cold starting of course but does it make that much difference over and above other potentially cheaper measures, I dont KNOW and nor does it appear any one else

I am open to be persuaded it does though

I seem to recall that too, not sure of the details I was told years ago that regular changing of oil using a decent quality can reduce gum and sludge for minimum effort

That comes with the kit instructions

however theres a very easy way to deal with at least some of the human factor for just a few quid if youre using an electrical solenoid.

All you have to do is wire in a thermostat so it switches over once the engine reaches a certain temperature. For pre shut down (and this is back to manual operation) you put an override switch into the circuit to switch back to diesel. Once youve switched off the ign switch the switch back so once you start up next its back to auto.

still a faff but only about 50% of previous plus takes the guess work out of switching onto svo
