Has anyone had any experience using this? I found a couple of others asking the same question through search, but no one responded.

I'm wanting to use booster to prevent knocking on a 280hp WRX, rather than to increase power.

The tub says it increases the octane number by 2 to 5 points, and a bottle is suitable for between 40 and 70 litres - that's not particularly specific - anyone know any more?

Thanks

 

I do know 1 thing:

If you put in 1 bottle or 2 or 3 or 4, the increase in octane rating will be the same. There are only so many RONs you can add from the magic bottle.

The product to get is 104+ Octane Boost, from the USA. They sell it in Walmart, but not the Bristol branch, which is their only UK branch at the moment. They will be selling car parts later on, apparently.

 

See my post re emergency brake question, in a nutshell I can bring some Millers catted version for you tomorrow if you want.

See you tomorrow.

Cheers

Simon
