Fuel additive

[Mr Webb]

Are these additives you add to the fuel tank any good?

If so, can anyone recommend one worth using?

None are worth the money tbh! We ran it in the rarecars, but it serves a purpose there. We ran silkoline for reference...

Could maybe try methanol. Alot of guys from my subaru club do this. will need mapped tho

i've used octane booster, seems ok

what do you want from it, more power or just a cleaner engine?

 

[Mr Webb]

I was wondering whether there was anything available that might give the engine a clean and then as a result maybe increase efficiency/ power slightly!

I wouldn't bother with any of it really, any gain will be purely coincidental. The engine should keep itself clean enough if you are using good quality oils and fuel along with proper servicing.
Getting the ecu mapped correctly(not the usual chip change rubbish though) may gain a little power accross the revs if you've got some spare cash.
