My IP is cold enough to touch after an hour or so of running time so I fail to see how its heating the oil any further. I guess the last chance the oil has it to get the heat from the block as it passes through the injectors. |
I'm questioning if the fphe contributes anything at all to achieving proper combustion. My opinion is that it doesn't matter what the oil temp is on the way to the injector but the injector temp is what matters. If the oil is hot (80oC) and the injector is cold (20oC) the oil will be injected at close to 20oC. If the oil is cold (20oC) and the injector is hot (150oC) the oil will be injected at close to 150oC.
If there is not proper combustion you will know about it (rough running and smoke).
If you have IDI you don't need to worry too much about gumming. If you have DI you do.
IMO running 50/50 veg/diesel on the Sunshine Coast you should have no trouble at all.
I would consider running 50/50 (2 tank with startup on diesel) with no fuel heating at all.
Or even single tank and start on 50/50. Maybe 70/30 in winter in Sydney.
Sunshine Coast doesn't have a winter, just a summer and another hotter summer.
