How much octane can you really use? 2 gal in a tank that is balance of 93 pump gives 95.6 oct avg.
The seal issue is a concern, but elastomer attack by solvents is normally a time/concentration effect (high conc for short time is roughly equiv to low conc for extended periods), but unless you know exactly what the properties of the seals are, you run the risk of possible harm by having high conc.
Also, I would suggest adding something like MMO (Marvel Mystery Oil) or equivalent when running the T-sauce as it does not have any of the additives like pump gas. What the hell do they put in 101 Oct unleaded to get it that high? Is is more toluene? I don't know, but if you could find out that would answer your question? Might want to call whomever supplies it and ask if running it will hurt your fuel system seals - might get an approx conc of toluene and that would tell you what the upper limit is. I've run 2 gallons at a time before and never did any harm (that I know of...). If the weather is hot and you can get it, Xylene is 117 octane, but it has lower vapor pressure than Toluene (which is 114 oct), so I wouldn't run that in cold weather.
