Just looking for a quick opinion from you guys. Would it be ok to go from 94 to 92 octane once in a while (92 is everywhere, 94 a few pumps in the city). My car was tuned with uberdata and AFR is around 12. Should i just suck it up and keep getting the 94? Or could i drive around through the winter with 92 since i can't really boost with all the ice and snow?
Thanks

 

Winter gas in the city brings with it more alcohol to pick up the water than accumulate due to the lower temps. If you were tuned at 12.0 then I would do a test run and make sure it is going to not knock or ping, if you have a boost controller you could always turn the boost down a bit. But you will probably be fine , but make a few trial pulls and watch your air fuel and keep an eye on your knock voltage
