Ion -Just Gas?

I was told by my salesman,that the octane should only be 87,the computer is
calibrated to read this.Can I add some STP Gas Treatment?,I got 12k now &
it's been a brutal winter.

 

I periodically add a bottle of either drygas (isopropyl type preferred over
methyl) or injector cleaner. Keeps everything running nicely.

STP for fuel injectors my Saturn tech told me is a-ok once in awhile as
needed, as is cleaning the throttle body out with the proper cleaner.
Other additives may damage your lines or mess with the computer's readings.

I agree. Fuel injector cleaner and drygas won't hurt if used once in a
while.
