I own a 2013 Ultra, do you know if it has a knock sensor?

 

There is just no reason I can comprehend that would induce me to use 87 octane when 91 is readily avalable. And this whole ethanol thing is a non-issue anymore. Almost without exception ethanol is in all the gasoline. Just use some Star Tron occasionally. It takes so little and you don't have to use it at every refill. Just use the stuff, it works great. Unless you run an old cycle, 10% ethanol isn't going to harm anything. Star Tron is available at Walmart and hundreds of other places.

Note: Star Tron is not the same as Stabil.

 

ok so which star tron do you use.....the emzine fuel treatment or the gas additive? i found this on amazon in one of the reviews...i find it interesting:
"I had never heard of this product until I recently walked into my "20 something brainiac" nephews work shop and saw fuel stabilizer study he had undertaken for his own purposes. He had several different fuels from different companies (Shell, Citgo, etc.) in mason jars with different additives. In the jars, he had metals (both suspended and laying on the bottom). In several of the jars, some had turned the fuel hazy, was coating the side of the jar, and a green cloud appeared around the metals. In several others, the fuel was only slightly hazy and a light white cloud had formed. There was only one that caught my attention....not sure of the relevance of the fuel, but it was Shell with Star Tron...this fuel was absolutely crystal clear with no residue on the side of the jar. From what I witnessed, I'm making my own conclusion that this is by far the best additive on the market. "
I just might have to try it....looks like it cant hurt...at least a couple of times.

The Star Tron to which I refer is the fuel enzyme treatment. It was originally designed for marine (meaning boats) use because boat fuel operates in such a wet environment. I mention this because ethanol has an affinity for water (it attracts water).

Note: In the stores there are different concentrations of Star Tron, but it is all the same stuff. The bottle I have is something like one ounce to 16 gallons of fuel. So, obviously pay attention to the directions. However, having said that--the dosage does not have to be exact--says so on the label. Your first treatment should be a double normal dose--says that on the bottle also.

I also want to note that I have never had a problem with ethanol fuel even though I have a high-compression build on a 95" Screamin' Eagle--even before I began using Star Tron. Yet, I figured that water in the gas tank is a bad thing, so as cheap as Star Tron is to use, I assumed that a little caution would be a wise thing. I am not a fanatic about this. It just seems like a no-brainer though.

 

Yep I agree..

I'll never understand why some get so caught up on paying a little extra for the correct octane. What's the average fill up, 4 gallons ??? OK so at $.20 per gallon more for premium that's $.80 per fill up. You're going to fill your Harley with fuel that will more than likely cause issues for $.80..?? Really ????? Um Ok...

 

thanks albngore, appreciate the feedback.

Just trying to learn some things not argue. Does it still knock or ping using the premium gas?

 

I try to use higher octane, because I get better mileage and therefore more range. However, there are places, like in the rural western USA, where high octane is not always available, and your choice is 87 or nothing at all. I never had ping problems but mileage and power (measured by butt dyno) go down.

 

+1 ^

i don't have cash to throw around like some do....but at a dollar a tank, i figure it costs about $.25 an hour to run premium instead of regular gas. i have tried non-oxy a few times and i can't tell the difference.

 

I run 93 when I can find it no less then 91 unless I have no choice... I have never had any pinging with this new 103 not even b4 I put PV and pipes and A/C..I do use sea foam and ethenol shield ... the ethenol shield goes in any gas that sits for any length of time,,,,keeps the fuel from going to ****. I put a pinch in the tank of the scoot if it sits
