I live in El Paso, TX. Never in my life have I seen 86 regular gas. "Super" is 88 and premium is 91. I like to run the 88, but does anyone know what might happen if I go to 86?
Hmmm.....really, what year is yours? Here's what my '08 manual says.owners manual say to run regular unleaded gas putting in anything rated higher could hurt the system i doubt it but thats what jeep says
The only mention of damage to the system I could find was from methanol.FUEL REQUIREMENTS
All engines (except 5.7L engines) are designed
to meet all emissions regulations
and provide excellent fuel economy and
performance when using high quality unleaded
“regular” gasoline having an octane
rating of 87. The use of premium
gasoline is not recommended. Under normal conditions,
the use of premium gasoline will not provide a benefit
over high quality regular gasoline, and in some circumstances
may result in poorer performance.

EDIT>Oh I just saw you are in California, may be a CA emission thing.......
No uproar at all (see my prevoius post). I was just asking since I attached a quote directly from my '08 manual pdf which says nothing about damaging the system.
