Maybe that's why Honda recommends it, some engines need it, my ST 1300 for example, and some don't, using what Honda says to use gives you the most bang for the buck.

Yeah Honda recommends 86(or higher).

My Toyota Camry recs the same, but pings at WOT with 87.

Both my mustangs recs the same, but ping at WOT bone stock with 87/89.

Seems hit or miss, i always figured the 110 degree heat and humidity down here had something to do with it.

I'm just glad my bike is running smooth.

'86 vT500c

So someone said the 80's Shadows were ment to burn "premium".
Should I be burning a higher octane gas?
It runs damn well on 87.
Will I see any improvment in power and/or MPH?

More Fuelology

I'm no expert but I've played with different octanes. (Next step will be brand of fuel. It's all the same stuff but their additives can vary.) So I tried 'em all from 87-93.

For me and my 2001 VT1100C it's a toss up between 87 and 89. If I could run 88 that would probably be perfect. The vibration at 70mph is almost non existant with the 87 but I think she starts a little rougher. I'm still getting to know her cold, warm and hot starts so it could be me. There's definitely a noticeable difference in the vibration with the 89 octane.

I just started to watch gas mileage now. Might be losing some with the 87 octane. Will advise...

It's not the destination...It's all about the ride!

I have no idea? Don't know what a DC fuel transfer pump is or what it's used for. In the electrical world, DC usually means higher voltage and less amperage to run the same equipment. Suggest you ask the experts.

On the topic of Ethanol, on my CX forum there has been a great deal of discussion about the effects it has on 28 to 30 year old technology machines and carbs. Many there are doing everything they can to avoid it, even to going to a small local airport to buy general aviation gas *not JetA fuel*. Not every state has full mandate on the E10, so if you want to find out if you can get non-ethanol fuel near you, try this LINK. Running the base level of octane recommended by Honda is always best, no matter what the year. In my case, both bikes will get standard 87, and I'm about 30 miles from the only non-ethanol station here.....have not gone out of my way to get it. But I noticed a big (read negative) mileage and performance difference in my CX when we got the E10 here. I expect to clean carbs and fuel system more frequently while using it.

Just some thoughts.

I can't say I blame anyone for trying to steer away from fuel containing fuel. The auto manufacturers are starting to pressure the government now, more and more, to stop this non-sense. They got the E-15 blocked that the government was pushing for... let's hope that they can make this retroactive to E-10 also.

With that said, running AV gas in a late model vehicle isn't a good idea either. Yeah, it' a 'better' quality of fuel and has no alcohol, but it does still contain lead. Leaded fuel in a modern engine will eventually cause problems, such as build up... and will flat out ruin a catalytic converter, which some newer motorcycles have...


Gasoline is for washing parts, Alcohol is for drinking... NITRO is for racing!
