I run the high test in my 3.2 911 and I only run good brand gas too. I aim for Shell and then Mobil/Exxon if I can't find a shell. The problem you will have is you can only find 91 in Maine, but my car runs fine on that too. However, I only try to fill it up in NH.
it is a very special detergent, and likely does other things; it contains a type of polyetheramine and likely other things
not sure if others have caught up to it, but Chevron has won law suits against other companies and their ad claims ("as good as, or better than Techron" etc.)
they do have 1,600 people in a single research facility dedicated to better gas and hold a slew of patents to protect that output...
Shell high octane V-power for my P-cars, Techron is a debate subject for some, I've been told if you use top tier gas which already has additives, Techron not needed.
Also thank you 911Dave for the list of ethanol-free gas suppliers, I may need to check it out.
Where I live Premium is 91. I use Techron Concentrate Plus once a year right before an oil change, but what I think is making a difference (for the better) is Sta-Bil 360 Ethanol Treatment. I use 4oz on every tank and the engine's elasticity has significantly improved. It may clean varnishes caused by the ethanol and it appears to clean injectors.
The ability to extend high gear performance (without lugging) to lower RPM ranges and the ability to smoothly accelerate from there. Engine elasticity means wide RPM range for high gears - 3rd, 4th, 5th.

I'm sorry im just not buying that. What you are talking about is torque. There is no way 4oz of anything is increasing the torque of your engine.
All engines required the same fuel. 78/79 regular due to the lower compression ratio. 80 and up premium and has been ever since.
