Gasoline (Petrol) with Ethanol
« on: April 05, 2019, 09:35:46 PM »
Hello fellow Tigers..
In Costa Rica, starting May 30 .. the super unleaded gas (currently 95 octanes) will be changed to 8% ethanol + 92% Super (95oct) gasoline.  Apart from being more expensive (and lower power).. what other effects can this have on my Gen 2 Tiger 1200?
Is it better to load up on Regular + octane booster?

Regards,
Patrick

you wont notice anything except maybe a tiny loss of fuel economy.... .....we get nothing but 10-15% ethanol fuel where I am and its been that way for over 10 years...... the only thing you need to be aware of is if you store the bike for 6 to 8 weeks with the fuel sitting in the tank,  you will need to treat it with a fuel stabilizer as ethanol tends to absorb  water and if it absorbs enough, it will come out of suspension and settle in the bottom of the tank.... ...

Yeap. I've been living with 10% ethanol for almost a decade now. First year I put those additives to my fuel, then I forgot to put them and I noticed that I didn't notice anything - anything at all. No performance drops, nothing...

So, don't worry about it.

I choose the fuel with the lowest percentage of ethanol if I have a choice, just because it is hard on things like fuel lines etc. especially on older bikes. I find it also fowls the injectors a bit. I can always tell when I've been running gas with ethanol, because my TEX will stumble a bit at a cold start.

What octane is your "Regular"?  Do you need any higher?  Have you looked it up in your manual?

Nope. I didn't look anything up on the user manual.

I put 89 octane to all my vehicles. All my bikes, my wives bikes, my car. Everybody gets 89 octane (the middle button in most gas stations here in the US) I have had zero gasoline related problems in my history of owning and operating metallic objects powered by internal combustion - I think that's quarter of a century now.

Compared to some folk on this forum, I am still a baby though...

I use Chevron 94 in my bikes and small engines because it has zero ethanol in it. It also has a double dose of Techron additive. Basically, I can store any of these over the winter with no fuel stabilizer required.

Ethanol has been blamed for the warping/shrinking plastic fuel tank problems that Ducati owners experienced.

Everything capt'n says is accurate :169: I've simply never experienced any of them - never owned a Ducati and never stored my bikes in storage for long duration. :821:

Our regular (no ethanol) is 87 octane. Our premium (no ethanol) is 91octane and in some areas 94 octane is available. I use 87 regular until it gets above 85° F and then switch over to premium, because I sometimes get some pinging at takeoff once the temps get hot. I can only remember filling with ethanol 3 or possibly 4 tank fills over the past 7 years I've owned the bike. That was on a trip around the U.P. where that was the only fuel available and if I recall correctly it was 89 octane. The bike ran fine on the ethanol fuel, but I did burn out a donut on the exhaust manifold that trip. Coincidence? Maybe...

Ok, for those who can't or won't read the manual... the recommended fuel for my 2018 T1200 is 91RON.
It was the same for my 2015 TEx.
So that's what I put in it.  (I also do oil changes around 16000km, ie at the recommended service interval.)

In Australia, 'standard' is 91, 'premium' is 95 or 98.

I've tried higher grade fuel, and the very slight increase in distance didn't make up for the extra cost.
So I think anything higher than 91RON is a waste of money.  (Same for my Subaru Outback car.)
-I don't use ethanol-added fuel.  So far, I haven't been anywhere where that was the only option.

I'm currently holidaying in New Zealand (in a car).  Standard seems to be 91 here too.
