New Zealand fuel economy

Has anyone from NZ seen this?

Heats the fuel. They also claim a "vortex" which I consider BS. However, for cruising conditions heated fuel may well give better mileage.

Since these guys are from NZ and we have several on Lextreme from NZ maybe someone has seen real life numbers.

They have some tests posted but anyone can create numbers.

I have had customers use the diesel units with success, and I can see how preheating diesel can work well. I am less than sure on the petrol units. Cheers

Damn I try to cool the fuel as much as possible! haha

Cooling the fuel should cause a greater drop in intake air temps and that could add power. Heating the fuel could improve vaporization and that could add power. Hmmm...

I know you can't get "snake oil" any more but it seems the salesmen are alive and well in NZ.
