Comments: Fine system, but most expensive to buy, install, and use since it requires use of new SVO, and has no provision for use of diesel once the engine is converted over to SVO, AFAIK. If used for what it was designed to - use new vegoil only, it's a very good system of course. Comments: New Canola oil will stay liquid down to at least -10C. WVO won't, and it is more viscous even when it does flow. Probably down to around freezing is the best the same oil is good for once it's been in the fryer a week or so. If you have optimized the engine for more complete combustion of vegoil AND if you use only new, pure, less viscous (compared to WVO) SVO, then likely there's less residue in cylinder at shutdown, so less of a buildup occurs. That's the answer to your question on shutdown without a diesel/biodiesel purge, IMO. But starting on WVO is a bad idea, just by virtue of the fact it is thicker material even if it does flow. WVO in a system designed for SVO would likely lead to poor starts and higher emissions on single-tank cold starts, and more deposits in the cylinder than what the system designers found with the SVO. It would be more strain on the pump, as well, since the pump would be cold on those cold starts and then right away put into use (a load applied, for example, by driving away vegoil right after a cold start), and again WVO would make the problem worse due to its higher viscosity compared to SVO. Heavy footed drivers would add further to the problem. . So again, just IMO, re: single tank/two tank, and general use, and use in cold..... Two tank, IMO, is best, for low initial cost, for flexibility, for starting out, for use with weaker pumps, for use with WVO. Electric or hybrid electric/coolant (underhood coolant operated heater, not HIH....MAYBE hose-ON-hose, MAYBE an undertank loop or very good in-tank loop that is as failsafe as possible) ... gives maximum utility at lowest cost of material and cost/ease of installation. Single toggle switch is simplest operation. Optionally, a vacuum gauge gives good indication of filter condition. Separate filter provides redundancy in case of a filter plug. Six port gives flexibility for loop/no loop provides for purging of air simply, Overall ease of operation, installation, reliability. Larger diameter SVO line reduces load on pump, improves fuel delivery, performance. Tank heaters are needed mostly overnight, so 110V/230V (on a timer perhaps)...not 12V. - plug in a battery blanket around tank - it only has to be kept warm, you should be using a block heater anyway so should be near an overnight plugin or inside in a semi-warm garage. Plug it in, at tank and block heater ends. At work all day and no plug? Insulate SVO tank and lines well. Run a blend of some sort if its getting too cold for the WVO. Run lines inside if you wish. Finally, run good old winter diesel for start/stop, and biodiesel or some blend in the SVO tank, if the temps go to "Man, is it ever C-C-COLD out!"
