WITH 230K MILES IS IT A GOOD IDEA OR NOT TO USE SOME OF THAT GUMOUT FUEL SYSTEM CLEANER? DOES IT REALLY EVEN WORK OR IS IT A WASTE OF TIME?

 

TECHRON!!! A++++

 

From what iv read the shell vpower one is superb, its the same thing you get with their premium fuel so it definitely has to be safe

 

Cool, I picked some up at the auto-store, I was close to empty on my tank so I dumped it in at the filling station just before filling up the tank. Darn gas prices [:@]and espically since the car says to use premium gas also . Now I'm used to running premium in my Mustang which only see's about 2000 miles a year but the Explorer I always put 87 octane in. I assume since the manual suggests 91+ octane for the S80 that is what I should use!

 

well iv always found that midrange just makes no sense its halfway between regular and premium in price but only gives you 2 octane more than regular wheras i think premoum gives you about 5 more? so why pay half the difference for less than half... for me its either regular vs premium and i go premium always, yea it costs me mroe but i figure its just better for the car.. .id love to attest to the mileage difference it gives but i thrash my car everywhere hahah so i cant really give you accurate figures
