Your kind of stating a double negative; oxygenated is ethanol blended fuel versus non oxygenated as with out ethanol so your using normal almost amount of a ethanol blend for where I am from with about 10% usually as well it sucks....not a pure power maker unless more pure and then not on the gas mileage any more cost efficient really but with a ethanol set up say for e-85 and the appropriate fuel lines and pump and tune OK.....
'The green part of the equation is the ethanol as they think of it as green even though the friggin change to adding ethanol in gas caused like 50 years worth of greenhouse emissions from turning all the soil to plant the corn...a farmers boom and BS to those of use real motorheads. You have 98 octane which should help with not any knock and well excess actually for the octane rating....And BTW all gas has some oxygen content even pure gas........and usually is thought of as the additive though...take it from a old motorhead or read up.....

'Its no big deal you just have higher than normal ethanol our computers have a knock retard built into to avoid hurting the engine and would just pull timing if you ran crapolla fuel and thus why one thing on here is the fuel table reset by pulling a fuse to force relearning from low grade fuels to get to the higher octane fuel rating, there have been many posts on this especially with dealerships using low grades for the car from the lot being cheap. Anyway remember good old Ethyl? that's top of the line non oxygenated gas higher octane and the bomb for a good old engine, now a days though you can hardly find it anywhere and engines are made for the ethanol crap and even now small engines though its bad for them and varnishes them with the additive if not used regularly or a stabilizer added....You should be more worried if you and in-oxygenated...LOL its the norm now in other words and sucks because its hard on gaskets and such in all small engines....and your tuner if you told him most likely would have said; of course your running oxygenated.....????? its simply helps the other fuel burn more completely making lower emissions....... Now if you were like way high on the ethanol you would want to run richer and the mileage would go down but power could be up some.... Read up. Adding ethanol is a big Lie to being environmentally friendly also BTW as those 50 years is how long it would take to run ethanol in all cars to overcome the damage done just growing the corn..... just to supposedly save a little emissions...because greenies matter to liberals for votes...and are especially vulnerable and stupid....
