Guys, what are you thinking, you can save $1.00 per tank full using the 87 over the 93 reguardlessthat the factory recommends 91+, remember they arethe onesthat design and build the engine, what do they know? and......if you go with no name gas, way off the beaten path you can save an additional 1/2 cent per gallon. cha ching!!!

In just a few years you will have saved enough money to replace the engine that was destroyed using the lower 87 gas. Sounds like a real savings to me, and don't forget about the WalMart autmotive oil filters and recycled oil, you can save big on that as well.

 

IMHO - run 91+, run Shell for the additives.
Like others have said, if you run lower octanes you have a dice throw of having a $3k TO $6k engine repair. But hey, good excuse to get an S&S 124! so go for it.

Run only premium fuel on both 97 Dyna Wide Glide and 07 Ultra Classic. Most times only putting 4 gallons per fill, so the cost is nothing compared to potential headaches from low grade fuel. I also run mostly brand name fuel. Less chance of getting crap or substandard fuel. I have never had a problem with my EVO engine in the 10 years I have had it. Just my opinion.

 

Only thing I run unleaded in is my lawnmower.I get better milage out of using premium unleaded in myChevy and Harley.

 

I try to avoid any 91 octane................93 octane is all I use.

I'm going to pick up a few gallons of racing fuel and keep a small bottle in my saddlebag, so when I'm in an area with crappy gas selection and get stuck with 91 octane, I can put a little splash of racing fuel in to boost the octane up.

Out here in Vegas and Cali you can't find 93 or that I have seen. Only 91, 89, and 87 or 100 which is way expensive and rare to find. I was using Arco for awhile till it started knocking on a long uphill grade. Now only use Cheveron or Shell. I know that all gas comes out the same hole and down the same pipeline. Its the additives that they use at the final point that makes the difference.

 

I know a fellow who avoids stations that don't have 3 separate handles for each grade. His thought process is that you are getting a hose full of garbage gas at the stations with 1 handle/hose. Crazy? Probably. Although I never thought about it until he mentioned it and now I find myself looking for stations with three handles at the pump.

 

If 91octane is the best grade you can get............ Then YES... And use NAME BRAND FUEL...

there is aVP racing gas station in san leandro ca that has 93.5oct 91oct and 100oct. at the pump i filled up my tank with 100oct( $26.00) but it got rid of the pinging in my scooter.

 

Having just done 6500 miles over the last four weeks including five days in Sturgis. In some states, I could only find 90 octane which led to pinging under accelerations. In South Dakota it was 90 octane with 10% alcohol. This caused lots of pinging. In Ohio and surrounding states, 93 octane is readily available, and no pinging.
