Hello, I have just one the idiot of the century award. Here goes my
story which explains just how smart I am...

I was riding home yesterday on my 2001 sv650. I went to fill up when on
the fuel light came one about an hour from home. I was slightly
distracted after just checking some phone messages. I saw, 87, 89, 93...and
grabbed at the right most one. I put it in the tank and started to fuel
up. For some reason I stopped quickly and looked at the pump. 1, 2, 3,
4.... 4 fuel pumps??? I looked at the price per gallon (not right) and
then back down at the levers. Doah...DIESEL! AHHHHHH! All pumps were
the same size. The 93 was next to both the unleaded 93 and the diesel,
but there was no sticker next to diesel like there is for the other
stickers with the octane level on them. I didn't even realize there was
diesel. Kinda stupid but also somewhat natural to just grab the one with
the 93 next to it since it was right-most just as the sticker was....ok,
stupid. An hour from home. I only put in 1/3 of a gallon (.3). I DID
NOT start the bike. I spent the next 1 hour and 45 mins in a gas station
parking lot taking apart everything I could find to try to drain the
tank with no luck. If someone knows how to do this let me know? I
disconnected many hoses but must have needed to do something else.
Eventually I went to siphoning the gas. I spent another 45 mins. obtaining a
hose, siphoning, and cleaning the gas off of my body and rinsing out my
mouth (yes some got in but not down the pipes). I was able to get out
a bit more than .3 since there was obviously still some gas in it when
I filled. I could still hear a small amount of gas when I wiggled that
tank back and forth after siphoning but could get no more out. I ended
up filling it up with 93 at this point. The tank holds 4.2 gallons. I
put in 4.2 gallons so am not sure how much of any diesel would have been
in at that point. Some very small amount of an already fairly diluted
mix I would have to guess was there before I filled with the 4.2
gallons.

I probably would still not have ridden (not sure what I would have
done) but I was on the phone with someone online who seemed to suggest I'd
be alright. I did my own checking when I got home and am uncertain.

So, what should I do? Do I need to find out how to redrain all of this
out again, clean the carbs, etc or what? Am I screwed? Will I be
A-OK? The bike rode home an hour or with no unusual behavior at a large
variety of speeds and rpm ranges.

What a stupid thing to do, but the labeling on the pump did not help.
Granted it was black in color. I will not take offense if you want to
remind me how stupid this was.

Thanks for your help.

don't worry about it. Worse cas scenario is the bike will run like crap until you get the Diesel run through. Diesel in a gas engine can only cause it to not run but can not cause long term damage. Gas in a Diesel engine however can destry it.

The solution to pollution is dilution!


Did it run ok after you got back on the road?

Guess I'd check your plugs, but chances are you're good to go, unless maybe you have done extensive modifications to the engine. If you're running stock, 87 octane is the gasoline you want, 93 just lines the pockets of big oil fat cats like our v.p.



Now gargle, rinse, spit, and repeat!! ;D Yech...

Yeah, I think you're good. Have a cold one and don't fret about it.

If I remember correctly there is a vaccum petcock on the tank, which means you would need to apply a vaccum (by sucking on the tube) to the vaccum line coming from the tank. This should allow the petcock to open and allow the fuel to drain.

I'd want some body to confirm this tough as it's been over a year since I worked on an SV.

I think you'll be ok. If you ran it for a hour without incident the diesel's long since diluted and gone so I wouldn't do anything to the bike.

You're certainly not the only person that's ever done this. It's odd that the system's not idiot proofed, at least for cars. Back when leaded gas was available the nozzles were different diameters so you couldn't put leaded in and unleaded-only vehicle. There's probably a reason why it's the way it is, but having both fuels at the same pump and using the same colors doesn't help.

Looking on the bright side, you'll probably never do it again...

Welcome to the board!

I hope everything is OK. That small of an amount, when diluted by a full tank of regular gasoline hopefully won't hurt anything. A question though... I gather from your post you thought you were putting in 93 octane or higher. Is this correct? If so, you are wasting money as the SV650 engine is calibrated to run best on 87 octane. There are numerous threads here on this subject by the way. If I am incorrect about how I read your post, I apologize. Thanks, Mike.

Yes, I will NEVER do it again. It was not a good experience.

I did try sucking on the tube (on the bike, no funny comments!) but nothing came out. I believe it references this in the service manual as well but it didn't work for me. I tried twice, maybe not hard enough.

You should be alright, I would top off the tank again 8)

Your real problem is running 93 in your bike, if you were running 87 none of this would have happened ;D

I will probably check the plugs and possibly change either way. There is a pipe on the bike, thats it, so maybe I should be running 87...

yes, it is a vacuum petcock.  there's a tube going from the rear intake boot to the gas tank near the fuel line.  If you suck on the hose fuel comes out (don't say it Doug or Josh  :p ).  Cranking the engine will open it as well.  

I'm pretty sure that all bikes made in the past few years are required to have a vacuum petcock.

+1. using 93 in your bike will not give you any performance upgrade, nor will it extend your bike's longevity; it might even hurt it long-term. go by the manual (87, all the way); anything with a higher octane is a waste of money.

Did you have your tool kit the bike comes with? If so why didnt you just use the allen wrench to take the two front screws out that hold the tank to the frame, prop the tank up with your prop rod and remove the rubber hose that feeds the fuel from the tank to the pet cock? I know there is a rubber hose with a factory hose clamp somewhere in the loop b/c I have drained my fuel once while at a camp site so I could gas up my dirt bike after we had run out of gas and I don't remeber it being too hard to do. Diesel being heavier in weight to gas would have dove right to the bottom of your tank too so you would want to drain it. Alos, the diesel pumps I have seen do always have a larger diameter fitting than the gas ones. Obviously this would still fit in your bike but someone had mentioned that the diesel is no longer a larger fitting.

I blame it all on cell phones I hate those GD things I would not own one to save my life when I am away on my bike I want to really be away no calls no crap nothing. I think this guy did this b/c of something to do with his cell phone. They are evil little devices and they fry your brain too just ask Johnnie Cockrun about that.

yes, i had the toolkit and used it to do exactly what you said. i must not have done something right as no gas came out. if the diesel fuel was the heaviest and sunk to the bottom of the tank, that would indicate that i must have already burned through it in my one hour ride home if any was in there. also, if the hose was all the way at the bottom of the tank, that would mean the diesel would likely have got sucked out first when i siphoned...right?

87 octane best for all SV years? I even put 92 octane in my John Deere lawnmower because I think its bettter!

NEVER SIPHON GAS BY MOUTH!!! Even if you don't get any liquid in your mouth, you are inhaling
gasoline vapor. Not good for you. Don't risk your health to avoid damage to your bike. You can
fix the bike.

Sucking on the petcock vacumn line is probably ok.

YUCK!!!

Shouldn't hurt the bike at all... hope you don't smoke cigarettes though!

Seriously though, I wouldn't worry about it. If you're really worried, pull the plugs after a few days and check 'em.
