Toluene... pretty good stuff.

kday · 06-04-2005, 11:02 AM

I've been having a knock issue with my MTM 1+ setup the last few weeks. I don't know if it's because we're still on winter gas and it's warmer, or what, but the last few tanks (from different stations) have been worse for detonation than ever.

I added 1 gallon of toluene to 17 gallons of Shell 93 today, and it got rid of almost all of the pinging. I still got an occasional rattle when mashing the pedal in higher gears around 3000 RPM. I think I'll try 1.5:17 for the next tank.

It's a PITA adding it though. Next step is water injection...

Have you ever actually ran the tank down so far that it took >75L to fill up? I think the one time I ran out of gas it took less than 20 gallons.

Sherwin Williams in this case. The price didn't seem very good ($13/gal) so I am going to call around.

I've added 9 L of toluene to 71L 94 octane. __________________ Naturally, IMHHEO(tm), Dave F. aka the Librarian Car and Mods: 93 S4, 1.8t coil pack conversion (First in world using integral POS coil packs (??)), CF (OE), S6 steering wheel, RS2'd, Samcos, MRC, TDS-1, Apikol FMIC, Eibach/Bilstein, BIRA Sys 1, relayed FP Click here to link to the UrS FAQ Thread Start Uncle Dave says "You want my 'high horse, elitist' opinion ?(IMHHEO(tm))Then just post something stupid."
