Had a rather humorous conversation with a fellow Detroiter who's dad owned a gas station.

Basically he said that in any metropolitan area carrying 93, you'd be better off getting 87 and putting octane boost in, vs buying 93.

Theory being that 87 gas station tanks get filled weekly, and very few people buy 93, so that gas can be sitting around for weeks if not months.

Our bike are fine with 91. (in fact the owners manual calls for it)

I'm guessing not many bikers who live west of the Mississippi are buying cases of octane boost every year.

Weird thing is that in Michigan, and many other midwestern/east coast states, you can get 87, 89, or 93. Thats why we opt for 93 here.

 

I am constantly on the lookout for gasoline stations in upscale neighborhoods with BMW, Porsche et al on the streets. Reasoning being those are the stations with customers who regularly buy premium gasoline thereby keeping the station's supply of premium fresher.

Folks I know in the local street racing game know which stations NOT to buy from but finding stations with fresh premium keeps changing.

 

91 is what your bike needs it runs better on it than 93 unless you really jacked up compression. Higher octane does not mean better. Never did.

 

Higher octane means you can use more ignition advance. I like to use as much of the power stroke rod angle leverage as possible.

 

That's interesting...I have no need for 100 octane fuel and the $7.00 per gallon is way out of my league, but I've never seen gas stations in my area to even offer this.

 

It' Texas...why not! Yee Haw!

 

I believe the new Dodge Demon requires the 100 octane fuel to get the maximum 840hp out of the beast. Otherwise on 91, it's a lowly 808hp.

 

can our bikes run on 89 without issue on a regular basis? bike in question is a 2015 street glide w/slip ons , fuelmoto air cleaner and powervision with a tune from fuelmoto.

 

I have had issues with 87 octane in a built motor but I am also only at 600ft elevation. I just got back from a trip out west and it ran fine on 91 but like the OP I wondered why the 93 dissapeared from the radar screen after Indiana.

 

Anything above 87 out west is scarce because they can't afford premium due to housing costs
