LPG on AE86? Is it smart?

[Blackmane]

It does, gas is indeed more dry than gasoline and tends to wreck the engine pretty fast. Modern engines and LPG installations can handle it pretty well, some carmanufacturers even build them in from factory if you want to.

But don't bother with it on older engines, especially performance engines and high revving engines. They don't respond well to the dry mixture.

Another thing is that the engine will get less mileage out of a litre of LPG than it does with gasoline. Couple that with the added cost of installing the LPG and extra maintenance and you'll have to drive quite a few km per year to make it economically viable...

But that's just my two cents...
