More details..........what % do you mix it at? Do you pop it in before a refill? Any special pointers?
between 10-30%. no more. anything more than 30% of toulene and xylene and you will have cold start and combusting problems. Also dont forget to use a lubricant also when using these two chemicals because normal petrol has lubricants in it and by using these large volumes of these chemicals dilutes them. Normally something like marvels mystery oil or very small amounts of ATF fluid.
I have done a huge post on this before in another forum....but using a 30% by volume of toulene mixed in 98 RON fuel is 105 RON, and xylene is 106 RON. Using this in the proper proportions is perfectly safe.... known people who have used this stuff for years. You should be able to pick of these chemicals at a paint store (used in paint thinners) or DIY store. Just make sure its just straight toulene or xylene and you will be fine.
as far as price goes its cheaper than any 106 RON race petrol, or octane boosters for that matter. Octane boosters dont really work that well and most will never raise over a 1 or 2 of RON. The best octane booster tested in recent years is NOS octane booster. It has been tested at 3 ron increase. Nothing else seems to even come close....but its expensive. If you happen to look at the NOS booster bottle..you will discover a large ingredient happens to be toulene. Go figure

Most people are like "well put two bottles in there". Well IMO thats a bad idea. not only for the expensive costs. But most octane boosters have other chemicals such as cleaning detergents and such. and used in larger quantities than originally designed for could damage your engine. Ever wonder why your plugs are yellow after you have been running octane boosters?
toulene or xylene. the only way to go on a budget.
