Adding gas to mix with my oil in the oil injector

I'm sure everyone has heard of people adding a small amount of 2 stroke oil to their gastank as a "just in case" type of scenario. What about adding a small amount of gas (or something similar) to there oil resevoir to help with the cold weather pour point or to help reduce the possibility of a lean condition. Not a large amount...maybe 4 or 5 ounces to a gallon of oil. Is it possible that if the sled sits over the summer that the mix will go bad and then have to clean the entire oil injection system? I'm brainstorming for ways to prevent a burn down. I manually clean my carbs but still think about running lean in the back of my mind. Is this a dumb idea?
 
I would use MMO personally. I am trying to understand how the gas would mix with the oil, it is not soluble so it would float. Not a good idea.

MMO or Seafoam is what you are looking for.
 
I am from Wisconsin and remember the harsh Winter Seasons there well! That said I recommend that you substitute 20% MMO on your next oil change. The vehicle I had there required 5 quarts of oil and I just used 4 quarts of oil and 1 quart of MMO at each oil change.

Helped cold weather starts and kept things clean.

Too you can add 4 oz of MMO per 10 gallons of gasoline at each fill. Just add the MMO to the gasoline before pumping so it gets mixed up good.

Float? Not soluble?

Ahhhhh....yeah....

I could be off base here but people have been mixing oil and gasoline for two cycle engines for say...... since the engine was invented.

Pretty sure there won't be any issues mixing gas with the oil and snake oils aren't required. I inadvertently added a quart of gasoline to my partial jug of two cycle oil. The thinning effect was very obvious. When I used up that oil, I had to remember that it wasn't 100% oil and had to compensate for the gasoline content when mixing it.

The question I have is, why would you feel the need to mix gasoline with your injector oil. The two cycle oil you buy is formulated for oil injector engines. No need to mess with it.

By the way, you can mix a bit of gasoline with the oil if you want but not too much. You'll reduce the actual amount of oil going to the engine and risk lubrication effectiveness. Personally I wouldn't do if you have two cycle injector oil.

If you were in a dire situation where you had no choice but to use an alternative oil of a viscosity that would not be suitable for oil injection, adding gasoline would probably be the only way to go. Unless of course you had some other additives around that could provide the thinning properties you're trying to achieve. However, why bother when gasoline will do the job.
 
Thanks Boraticus, great response. I get paranoid about running my engine lean (on gas) so I thought a little more gas in my oil injector might calm my paranoid delusions. LOL. I checked my injector adjustment a few times and it appears to be right where it is suppossed to be. But my sled still smokes like a b**** and my plugs are always wet and black. So my thought is more gas to the mix. I think I'd rather run rich than suffer a burn down.
 
Just use a decent quality snowmobile oil (a synth if you are really concerned about low-temp flow) and you`ll be good to go. Snowmobiles run daily in the high Arctic with no problems, they`re designed to deal with cold weather (as is the oil they are designed to run with).

I recall this type of discussion/concern being prevalent in the early-to-mid 70s when oil injection first came out. If the sleds ran with the (relatively) poor oils available back then, they can surely run with the premium, high-tech stuff we have now. BTW, every two-stroke sled now comes with oil injection and this certainly wouldn`t be the case if oil flow (and the resulting burn downs) was an issue.
 
2001 Ski-Doo Formula 600. Not the greatest sled in the world but it's in exceptional shape and I want to keep it that way and some how still ride it, LOL. One more quick question...mixing 2 stroke oils. The reservoir was half full of XPS mineral oil and I filled the top half (about 2 quarts) with Mystik Sea and Snow. That shouldn't be a problem, should it? I mixed an ounce of each and let it sit for over a week and it looked good to me. So I figured it would be good to go. It's not like mixing uranium and plutonium..they are both 2 stroke oils so all should be good, I hope.
 
I believe that one of the requirements for TC-W3 certification is that it can be mixed with other TC-W3 oils. AS for your sled, the 597 Series III Rotax engine is bulletproof. Run good oil, clean your Raves, warm it up properly before running it hard and it should last a long time.

Good luck and ride safe!

You're not running the engine hard enough or your main jets are too big for the type of riding you're doing. It's not your oil that's causing those symptoms.
