ExTex Posted August 10, 2014 Share Posted August 10, 2014 I see to use "Premium Fuel" but that is from the English owner's manual. I wonder whether mid grade or premium US fuel is acceptable ? Have any owners experimented with different brands or grades of gas ? Ride Safely, Link to comment Share on other sites More sharing options...
Guest MXRider Posted August 10, 2014 Share Posted August 10, 2014 Plenty are reporting no problems using 87 octane fuel. This bike is fairly low compression and has a mild tune so pinging shouldn't be an issue on a stock bike. Link to comment Share on other sites More sharing options...
Lusiphur Posted August 10, 2014 Share Posted August 10, 2014 My US manual says 87 Octane is fine. If you have not tuned an engine to use higher Octane, you are simply wasting money by putting in the more expensive stuff Link to comment Share on other sites More sharing options...
Cruizin Posted August 10, 2014 Share Posted August 10, 2014 I just use 87 octane and then drop a couple of Viagra in the tank. Can't keep the front wheel down though. Yamaha MT-10 ForumYamaha Tracer 900 Forum Yamaha Ténéré 700 Forum Link to comment Share on other sites More sharing options...

How do you figure that 11.5 to 1 is "fairly low compression" Congress is the only whore house in the United States that loses money. Link to comment Share on other sites More sharing options...
qjohnson Posted August 11, 2014 Share Posted August 11, 2014 I'm gonna use 89 or 91. Whichever is the mid grade at the gas station. But I've always wondered, you know the gas pumps at gas stations that only have one hose and nozzle? Since were only getting a few gallons or less, are we still getting whatever fuel grade was left in the line from the last guy that filled up? Let's say you just wanna top off your tank with premium. So you go to the gas station and pick premium. You top it off and it's only about a half gallon of fuel. Are you getting the regular fuel that was left in the line from the last guy? Or do the gas pumps drain whats in the hose after every use? I've always just wondered. Link to comment Share on other sites More sharing options...

A 2015 YZ250F has a 13.5:1 compression ratio and will run on 91 octane pump gas. Link to comment Share on other sites More sharing options...
qjohnson Posted August 12, 2014 Share Posted August 12, 2014 Bump for the one fuel hose per pump question. Link to comment Share on other sites More sharing options...
Guest unknown Posted August 12, 2014 Share Posted August 12, 2014 Most gas stations these days have 2 storage tanks; one for premium and one for regular. Any mixing is done by the pump or by the delivery guy if there are 3 tanks. My quick google-fu shows that the hose contains approx. 1/3 gallon of fuel in it. At worst about 10% of your next fuel (assuming you are near empty) is going to be regular grade fuel. That would equate to buying 93 octane and getting 92.4 Octane instead.

ExTex Posted August 12, 2014 Author Share Posted August 12, 2014 Guess I am lucky, all of the pumps I use are separate. Shell gas seems to give the highest MPG. Some stations sell higher octane gas at the regular gas price on certain days. Makes me wonder about their quality. Ride Safely, Link to comment Share on other sites More sharing options...
manuel Posted August 13, 2014 Share Posted August 13, 2014 I just use 87 octane and then drop a couple of Viagra in the tank. Can't keep the front wheel down though. hmm, or this might happen: http://www.asphaltandrubber.com/popular/bmw-motorcycle-erection-lawsuit/ Sorry for the thread jack. To go back in line - so far I have used only Shell VPower 91 AKI, ethanol-free. Bike seems to like it. Link to comment Share on other sites More sharing options...

Global Moderator mjh937 Posted August 13, 2014 Global Moderator Share Posted August 13, 2014 The station near the airport has a separate pump for the non-ethanol fuel. I am just going to fill up there. I like riding past the airport and looking at the planes anyway. Link to comment Share on other sites More sharing options...

Every once in a while you see something pretty cool fly in or out of there. Link to comment Share on other sites More sharing options...
Global Moderator mjh937 Posted August 13, 2014 Global Moderator Share Posted August 13, 2014 There are some really cool airplanes at Paine Field in Everett, about fifty miles south. On Thursday a formation of four P-51's flew over my house and a couple of months ago a MiG 29 flew over. They do not often get this far north though.

Guest montana07 Posted August 16, 2014 Share Posted August 16, 2014 I've used 87 and 89 and haven't noticed any difference. Always non-ethanol. Link to comment Share on other sites More sharing options...
John Posted September 1, 2014 Share Posted September 1, 2014 91 and chevron or shell. Price is not that much of a difference on these bikes. Greatness Link to comment Share on other sites More sharing options...

I've always just wondered. no need to run mid grade unless you rebuild the engine for higher compression. but, if it just makes you feel better to run it, make sure you fuel up after your buddy who pays for premium, if there is a one-hose pump. -HowWorkClutch Link to comment Share on other sites More sharing options...
aeisan Posted September 2, 2014 Share Posted September 2, 2014 What about if you have a Power Commander, EJK, etc. and run a map based on higher octane? Is that just snake oil or does the EFI mapping actually take advantage of higher octane, provided it's mapped appropriately? I used to run a Hypertech programmer on my Nissan Titan and I had different maps I could use, one of which required I run 92+ octane. No rebuilt engine, just an ECU tune. Life is good on 2 wheels!

Premium Member howworkclutch Posted September 3, 2014 Premium Member Share Posted September 3, 2014 If that device was mucking around with timing charts higher octane might have been needed, but it's not gonna really do much since the entire system needs to be tuned for the fuel. If you're curious you'll find lots of articles about octane and compression ratios. Most of the tuner stuff sold is snake oil. -HowWorkClutch Link to comment Share on other sites More sharing options...
aeisan Posted September 3, 2014 Share Posted September 3, 2014 Good to know. I got the Hypertech unit for the truck for free - my truck was the R&D guinea pig for it. I'm planning on getting the Dobeck EJK to pair with a new exhaust in the future, but only because they say it's pretty much required (currently leaning towards the Akra carbon set).

dede Posted September 5, 2014 Share Posted September 5, 2014 I want to stay away from Ethanol, meaning I must pump premium only. A one-dollar difference per fill-up is not an issue. Link to comment Share on other sites More sharing options...
Global Moderator mjh937 Posted September 5, 2014 Global Moderator Share Posted September 5, 2014 I wish premium was ethanol free here. I have to pay even more for ethanol free. Of course as you say when you are only buying a couple of gallons at a time the cost difference is not too bad. Link to comment Share on other sites More sharing options...
