View Full Version : PreMix Gas to "Wake Up" Sled
10-24-2009, 11:23 AM
How many run a little PreMix gas(say >1/4 tank provided it was stored empty), at first start up, after summer storage?
10-24-2009, 12:32 PM
the fogging oil I spray in during spring storage makes a big enough cloud during start up

Not necessary, PLENTY of oil in a fogged motor.

I run pre mix first tank of every 2 stroke I have, every year. One year had an oil pump give out so I learned my leason the hard way. If I would have had done the pre-mix thing then wouldn't have cost me $600 for a $100 part. That way I can check my oil useage and worse comes to worse have to change out a set of fouled plugs.

Now that makes sense dab102999. I just thought it would be more polite to the engine. In your case it would have been way more polite to the wallet, too! Running PreMix, first tank, from here on out. Thanks.
what happens if oil pump goes out on 3rd tank is it not just as likely?
10-24-2009, 11:25 PM
Or the 5th?

Nope first tank, that is the only one that can do it.....

Yea as soon as you said the 5th I saw where this thread was going...but in my case I am so pumped about riding that first ride that sometime I don't think about looking at things like the oil level. But once that first ride is out then I come to my sensus and check the oil everytime I stop for gas. I used to use a marker and put a lime but found out that can get confusing after a couple of year. now I just use a piece of electrical tape to mark the oil line and make sure it uses some...but seriously 42 law in murphys law says that everything that can go wrong will go wrong on my first ride of the year!!

dab, your idea is great. I do the same thing for the same reasons. I had a oil pump go bad on a 03 Polaris 700RMK on 1st ride of season. I also add extra oil to tank when riding in Mountains with carbed sleds. I don't totally trust my jetting for altitude. No meltdowns this way. Plugs are cheap compared to Pistons.

Problem is the oil pump will break while your riding. By the time you realize the sled isn't getting any oil it will be too late anyways. So marking your oil tank won't help at all. You meen to tell me that if you check your oil level at a gas stop and the sled hasn't used any oil that the sled will still be running....not. I understand the theory but it doesn't work that way. Sorryhttp://www.johndee.com/discuss/clipart/sad.gif
I don't know that your extra oil to prevent lean burn down makes sense.the oil wont burn off like the gas so if you think about it the more oil the more lean you will be running.maybe I am crazy but that is how it plays in my head

I don't really plan on pre mix. If I have left over fuel from the boat, thats mixed, I throw that in there than fill the rest up with premium. What the ratio is, who knows, but I would believe it would be better to pre mix a bit on your first tank of the year. I remember a dealer mentioning it to me, not just for new sleds.

When you go to become a Ski doo certified mechanic they tell you to add oil in first gas tank every year!<font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font><font color="ff0000"></font>

I'm with dab102999. I always thought the best chance of an oil pump not working was after it sat along time, like diapham rot, gasket failure, mice chewing the line, or if you worked on it, chance of kinking the line or air bubble if the sled was on its side for awhile.
What is the cost of that little extra oil - cheap insurance.
And I'm still going to use moth balls.

Do ya harvest 'em yourself?
That must take a good microscope and a tiny pair o' tweezers! http://www.johndee.com/discuss/clipart/happy.gif

frnash, that was good!! I had to read your response a couple times to get it. Too funny. Dab and lvr1000 I agree with both of you. I also added an extra 3 yrs. on my sled warrenty. Never can be to safe.

That's the difference between "moth balls" (two words) and "mothballs" (http://www.onelook.com/?w=mothballs&ls=a) (one word)!
Yeah, I'm back! http://www.johndee.com/discuss/clipart/happy.gif
smurfette loved to play with moth balls

Yeap, time to wipe the milk off the keyboard that came out my nose, thanks frnash

You should always consider the fact that the amount of oil you put in your gas displaces that same amount of fuel as it passes thru the jets or injectors.
If you are close on your jetting you may run into a lean condition melting pistons. All the oil in the world won't help a lean burn down. Overall, mixing oil in the gas tank is probably a bad idea.
Are people really having that much trouble with oil injection systems?
Been riding since way before oil injection came about and have owned an independent repair shop for about twenty years and have yet to see a oil injection system failure (except for failure to add oil to the tank when it's empty).

mikedrh, I think I understand what your saying, but explain this: Several years ago I accidently put 7 gallons of Diesel in an 11 gallon tank on an 800 triple.
Station clerk said I was the second sled that morning to do this, just go dump it in the woods.
WHAT!!! I chose to run the sled hard. As long as the RPMs were above 7000, it ran, below I had to pull the choke. I put another 8500 miles on that engine (16,500 total)
By the way, I thought diesel always got better mileage LOL I got less than 6 with the 7/4 mix but the looks from the smoke trail, priceless. I felt sorry for my buddy trying to keep up.

I usually hook a piece of wire to the oil pump lever and after its running pull on the wire. So the oil pump is pumping alot of oil to the engine. It will smoke alot but at least I know that the engine is getting plenty of oil. After it runs awhile I shut it off remove the wire and run it a bit more and then change the plugs. Never had a problem with a motor
11-05-2009, 09:29 PM
lol this is why I bought a 4 stroke...
11-06-2009, 01:11 PM
Why not add extra oil in the gas tank to your four stroke also?
It has all the same parts, and then some, that the two stroke engine has.
Makes even more sense to me.
11-06-2009, 06:48 PM
Because my 4 stroke doesn't require a mixed gas to run. Just 4 quarts of 0-30 and a new filter. I replace the oil and filter before every season and then every 3000 miles but I usually don't get to put that many miles on since snow in Iowa doesn't last long.
