octane booster

I guess they wouldn't

How would Mercury be able to tell whether the toluene was mixed in by you or by the refiner?

Toluene is a major component of 98 RON gasoline, particularly summer blends.

Some one says yes Aces, some says no...

If ACES had worked, it would be a major fuel additive used all over the world to save millions of gallons gasoline, not something peddled by people infamous for selling octane boosters that don't work.

Toluene it's not problem to get, just to calculate how much you really need...

Yep.

Straight forward math .

This one seems to work , I've tried it mixed with 15 gallons of 94.

It was in a car motor with knock retard computer spark advance.

Probably just MMT again.

Yep, that's what it is but if your new powerhouse Merc lives with knock sensors? Would still work with old carb and high psi. Found a few cans of some sled fuel additive. Oxygenator, forgot the name. Instructions say dial in richer jetting and adj ing to approach proper tune. I'll take a pic next time.
