I have used Techron for years. I found that Redline SL-1 works better in my 1988 911. It has an upper valve cleaner/ lubricant. For hard core fuel system cleaning, BG 44k !
Have to buy it from a auto dealer, I get it at my local Mazda dealership.
The Techron mostly for my everyday driver... GMC van.
