Since fuel is expensive in Australia($52au for 4litres of 20% cool stuff i was thinking of getting fuel online.Is it ok if i moderately change fuel(which ever one is cheaper on ebay) and what are the disadvantages of doing so?Also so far no body on ebay says they can ship fuel due to it his flammable,but a few people on here said it is pssible.What are some places that they do ship fuel to other countries?

The only way you can get fuel in Australia freighted to you is via a courier with a danderous goods license. You can't get it posted either because being classed as dangerous goods. If you really want cheap fuel then buy either a baja 5b or a fg 1/5 scale to run on regular (or premium) petrol at around $1.20-$1.40 per litre

Im sure massive mods fuel is available in melbourne, use that and you'll never use anything else.

yeh, we get that Over here in Perth, best stuff ever.

ok,and what would happen if i change fuels from time to time?

Nothing wrong with changing fuels just keep the % the same We have the same BS here in the states, I'm making a 3 hour+ drive because its over $100 to ship fuel to me[&o]
