Increasing Gasoline Octane Overseas

Off base the gas is 95 Ron which is equivalent to 90 octane in the US. I will see about finding some toluene. Any issues with running toluene as a additive? (Injectors/ fuel pump and lines) If anyone knows the ratio off the top of their head that be great. If not I will do some digging. I am not not looking to run race gas just get it up to 91 at least if possible.
