Cool. I have a 96 Tsi AWD but it is always in the shop and costs a fortune. Wanted the reliability of the Toyota plus living in New England with the winters and driving on major interstates with the 18 wheelers etc. The Talon is what I use to get to the train station and back and when I need a second car. The 4Runner is for everything else. I am hoping my "fleet" lasts me 30 years!

 

Hmm,I never heard of gas clogging injectors and the reason you use 91 in your Talon is due to the turbo and compression you need gas that's less volatile and only ignites when the plug fires. Turbo cars create a lot of heat in the combustion chamber and if that lesser octane gas ignites from the compression then you gonna have problems.

I used to drive and race a fairly modded Eclipse (roughly 350 crankhorse) and on the street 91 was fine but at the strip running 18psi and on hot days I needed 105 octane to keep the knock away and the timing advanced to continue making power all the way down the strip.

 

i run regular unleaded in my V8, runs just fine. There's plenty of power in that motor anyway. save your money for other goodies!

 

Thats pretty cool, I have a 92' TSi myself andmy 97' Runner That is pretty coincidental for all 3 of us You guys on any sites (dsmtuners for me).

Anyhow, like I said andrew; you dont have to if you dont want to. If for whatever reason your motor doesnt like it (im talking the new 4.7's) it will retard the timing and run totally fine. But I promise, if for some reason 91+ would prevent any knock or ping (high revs in low elevation or something) then you would notice MORE power out of the motor as it will run less conservative timing the higher the octane.

Also someone else said, there is plenty of torque in those things, I wouldnt put anything more than 87 if I had one (and my step mom does and tahts what we use).

 

thanks again for the help. yes, i use dsmtuners as well under the same handle. i think both vehicles have the best followings (pony cars excluded).

 

i get a good laugh out of guys that run mid grade or premium gas in their 22R-Es. i even run the cheap stuff in everything i have and i've never had a single problem, except when my timing is off.

 

Yup, same handle... dsmtuners, dsmtalk, and mitspro
