Gas for a fist.

Asked by GuruN5RW6 Oct 14, 2019 at 06:17 AM about the 2014 FIAT 500L Lounge

Question type: Maintenance & Repair

I been putting 87 gas into my Fiat 500L and the car
performance has changed. So now I'm going to
put 91 gas but I don't know if I should buy a gas
flush to flash my gas tank out. Or should I just
start putting 91 gas without using the gas flush?

91 octane is recommended. It won't hurt anything to leave and burn up the 87 octant fuel, Just drive as normal and when you fill up with fuel next , put in 91, no need to drain or flush anything.
