87 octane in a 2012

as many of you know there's a little bit of a gas shortage here in n.y. ... i only run 93 oct in my 2012 dyna but thats even harder to come by. i have plenty of 87 oct stored in the garage , what do you guys think? am i going to notice a difference with the 87 , should i ad an octane booster? or will that screw up the injectors? any help will be appreciated

It won't hurt anything, It might not perform as well. That's all.

Injectors won't know the difference. Hang in there you guys, I hope things start getting better soon.

08 FLHTC. Breathing well and getting lots to drink.

A lot of the little towns I ride through don't even have 91 octane premium. I've had no issues filling up with 87 octane regular in my 2012 FLTRX.

About the only thing I've noticed is a tendency to "ping" when rolling on the throttle if my RPM is below 2K, and less miles per gallon. If pinging becomes an issue simply drop a gear.

The screaming eagle octane booster works nice if you go that route, but the cost is equal to another gallon of fuel and probably doesn't help the mileage enough to warrant.

Yes it runs better on 93 but you do what it takes to get you down the road.

just for the fun of it: for the past week or so (ever since the gas shortage epidemic) the only gas we can find here in NYC is regular. Yeap. Regular. And every bike you see riding around the city is using regular gas. Including my Ozzy (Sportster Iron 2012) And every other rider I know - pick a make and a model and I tell you right away, it's been running on regular gas for the past week or so.

It runs just fine. No problems so far.

This summer I had to gas up with regular on a road trip. I only ran the one tank but did not notice any difference in the bike. I stayed off the throttle, made sure I was in the 2500 rpm range and it was good to go. I wouldn't do it all the time but in a pinch it seemed to work.

Gas in the garage was only a week old . I had about half a tank of 93 and topped it off with 87 . Ran fine all day and happened to pass a gas station out in long island with no lines and 93, so topped it off on my way home ! Alls good

I am running 87 octane in my '11 RG but I add my own octane booster, 4 gal of 87 unleaded with 1 gallon of 110 leaded racing fuel. My mileage is nearly 5 mpg better vs running the supreme 91-93 octane, 44mpg vs 39.2mpg. The price is a little more expensive, but no pinging, and the performance is even noticeably better. I was 2-1 regular vs racing, and now at 4-1 and that is where I will stay. After a couple of months I will run the numbers and refigure the averages...
Of course, this is of little help to the OP... I hope it is starting to loosen up a bit!!!!!!
