What do you feed your baby?

I have been fueling the Versys with standard (lowest rated) fuel / gas / petrol since i have had it.**

A V-Strom owner told me his ran much better on the middle grade gas, but he couldn't tell any difference for the highest grade petrol.

What do you use and why?

I filled up tonight with the best, so that it averaged 'mid' with the 'base' grade already in the tanl,

In the 1 mile ride home it seemed to sound better (or was that wishful thinking?).

** I purposely didn't put numbers into this post because different countries / different rating methods make numbers almost meaningless.

Although I have had Miss Jaffa (Burnt Orange 2007 Versys) for a while, I still have a lot to learn.

Hi Bigaussie,

In Malaysia, the "regular" unleaded fuel is 95 RON, "premium" fuel is rated at 97 RON(but for Shell 97 RON is V-Power), and Shell's V-Power Racing is rated at 99 RON.

I believe that higher RON burns better completely and better anti-knocking properties. Also, higher priced. Comparing fuels, I kept to the regular 95 here as the RON rating is already good for the V. Using V-Power once a month.

Webbikeworld first test on the V mentioned Kawasaki recommends minimum RON 91 and their findings.

Canadian regular 87 pump octane (RON+MON/2) gasoline has a research octane number of 91. Mid grade 89 pump posted octane is at 93 RON, and premium 91 pump posted octane is 95 RON... A minimum of 87 pump (91 RON) is recommended for the Versys.
Mine runs well on 93 RON. It's a bit more tractable at low rpm's, and gets slightly better mileage compared to with 91 RON. 95 RON doesn't help considerably more, although I do use 95 RON when only 91 and 95 RON are available.

bigaussie,

If you do a search you'll find a couple of threads on gasoline. Like with the oil threads, there is no concensus. I run regular.

Mine seems to run just fine on regular pump petrol with a shot of Fireball cinnamon whiskey added for good measure.

87 Octane. There is no benefit to running higher octane in a naturally aspirated, low powered machine. If the V (Versys for some ) had higher compression, or was known for running hot I would use higher. 92 octane may smooth out the low end stumble and pop, but no added power or mileage that I can tell.

Tried others, now I'm back to lawnmower gas..

I just try and avoid ethanol. Which living in a corn producing state is almost impossible. The lower energy mass of ethanol makes my mileage drop, and I hate that. I have never experienced engine knock using cheap gas, so I don't bother with higher octane, and in many cases the higher octane rating is achieved through the addition of ethanol.

When there are more E85 stations around here, I plan to run my bike on 100% E85 with the power commander for tuning. Worse mileage, but cheaper and more power. The oomph to cost is better and running catless doesn't have the pop on decel (yes I plugged the pair valve)

I had my tank and fairings off other day and the sticker on my tank calls for 91 octane. I had always read that our bikes take 87. I'll see if using 91 makes a difference.

I think the sticker references RON... not octane....

I could be totally wrong, but I saw the same sticker when I took my tank off last week.

Yep. RON, not octane.

This. It doesn't knock on regular. I am skeptical of any claims that the bike runs better on premium. Does the Versys ECU utilize a knock sensor, then change mixture and/or timing in response to whether or not a knock is detected? If not, I don't understand how running higher test fuel changes anything except my fuel budget.

Down here in Peru all the gasolina is leaded. I've been in rural areas where only 84 octanos gasolina was available, had to use it and my Versys ran well on it. I use 84 most of the time now, no hay problema.

Without the addition of a timing unit to advance it, there is no reason to even consider higher than 87... the one exception is perhaps riding in VERY HOT conditions where super hot intake air creates a possibility of detonation at heavy load... again... not gonna happen normally.

Oh yeah, I don't know if there is a knock sensor.. but its a modern motor, so MAYBE>??!

I'm running mid-grade, have been since I bought it. I've put a couple of tanks full of High test, but only when the other option has been regular. Didn't notice any difference with 93. I have consistently getting 52mpg, so I'm not going to change anything in the near future.

Have you actually done this? I'd think that maybe the injectors wouldn't be able to flow enough E85 to run properly. You may have to go to higher flow rate injectors. The other concern would be that the fuel system components wouldn't be compatible with higher amounts of ethanol.

I have not done this, but you raise the right concerns.

1.) I think a Power Commander V with auto-tune and a O2 sensor installed will be able to pump up the duty cycle to max, but I still may need larger squirters.... My friend had to double the size on his car for this and then tune it all over the place.

2.) I'm really not concerned about the modern components being effected by Ethanol. Unless I hear otherwise, this is the optimal setup for when I bite the bullet and install a TURBO!!!! Bwa ha ha ha ha ha!!

In Peru, leaded gasoline is available in 84 and 95 octane (RON?), and unleaded at 90 and 97 octane. Catalytic converter may be removed in Peru to accommodate the local leaded gasoline at more reasonable prices...
Leaded gasoline can damage and plug up the catalytic converter in the Versy's muffler.

There is no knock sensor on the Versys... I run 5 degrees more advanced ignition timing and it runs perferctly on 93 RON (89 North American pump posted octane) at 750' asl, although I haven't tried 91 RON (87 pump).
