I just ordered the Cobb Flex Fuel Kit for my '15 STi, I've researched the fuel plenty before so I know what I'm getting into ( Gobs of TQ and low detonation, that's what I'm getting into!!) anyway, but buddy with a GTR informed me that if you run E85 a lot, build up can occur and cause the injectors to gum up.
Do any of you guys use an additive? In the GTR community Star Tron is very popular (https://www.amazon.com/gp/product/B001VMNHX8/ref=ox_sc_sfl_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER) and in the 15+ WRX community Lucas Ethanol conditioner is popular as it lubricates the HFPF and makes a failure less likely.
I've also been told that since I'll be running Flex Fuel, as long as I run a tank of 93 Oct every few tanks, I won't need any additives whatsoever, as 93 contains detergents and lubricants.
Any insight?
