Oil mixed in fuel - extra precaution?

Does anyone run a little extra oil in their fuel as a precaution? Would 100ml per tank cause any harm? All 3 of my sleds have functioning oil pumps just curious if this would be of any extra precaution?
 

In my opinion this will do more harm then good. Was recomended on your fresh rebuilt sled as a "breakin in" or "bleeding oil system" procedure. There is plenty options of octane booster/fuel catalyst additives that do more than adding extra oil to fuel tank.
 
you would just lean out the motor and kaboom!!.When I rebuilt my motors 2 seasons back,just make sure you bleed the pump and you are good to go..My motors are still running...
 
100 ml would put the ratio at 454:1

Just was wondering if running like that every that every tank would have benefits or drawbacks. Sounds like drawbacks more than benefits
 
should be in the range of 50:1 ratio as a rule.Open your oil bleed screw from the pump.This is ahead of the carb rack center.Put some rags under.Open screw and let oil bleed out until steady stream.Tighten screw.Start motor up and pull the oil cable all the way open for about a minute or two.It should smoke as hell.Then you will know the oil is flowing.Then do a test when riding.With gas tank and oil tank full..go riding.Then when you are back..measure how much gas you have to add to fill up again and how much oil you add to oil tank.Do this patiently and mark down what went back in.Then you can calculate your ratio you are at from the ride you just did.Adjust cable more or less as needed to get that sweet spot 50:1.
 
For what you just paid dealer to rebuild sled I would follow their recomendation as for that kind of money it should have some kind of waranty. And to answer the other question on the other thread I would take it back for that cable adjustment as if you dont I am sure its in the fine print any waranty is void.
 
You Guys Are Totally Wrong On This. You Can Premix Your Fuel As A Precaution To Back Up Oil Pump, Never Ever Saw Issues, But Have Seen Oil Pumps Go Bad. 50:1 Backup Will Hurt Nothing. 3:16 (yammie Tony)
 
Correct me if im wrong and i also seen this on other post but if the oil pump goes bad it just dumps more oil than is needed this is a fail safe not to blow the motor if pump goes bad while riding

sounds about right from what I have heard or read over the years.
 
More oil = more power but mixing in tank may not be best idea. If your jetting is borderline it may cAuse u to run lean as oil is taking place of fuel in your tank. Also the 50-1 may be good for power valves but multiple tests show that 18-1 makes most power on 2 stroke. Going from 18-1 to 50-1 will b a about a 7% power loss. Now 18-1 is way to much oil plugs will foul etc but there have been dynos done showing this to be true. More oil= more power when jetted accordingly

The residual oil buildup in the crank case is what should determine if u are using enough oil. this goes for any 2 stroke. If your wide open all the time your oil migration time will be faster and you may need to run more oil.

not true,with more oil you would suffer more parasitic loss from the oil, also oil causes the gas to burn slower and cooler. more oil, loss power
 
there was a good article on this oil topic.Can't find it,but the guy mentioned that more oil equals more power to.I remember reading it and thought that was interesting.

When jetted normally yes roudyroy1, Hence the "jetted accordingly" portion of his post.
 
On occasion I do put a bit of oil in my tank when filling.Aprox 100 to 150ml to a tank with octane booster.. I have never had a problem nor have I had any power loss or power increase. I have done it just as a precaution when I am riding full out alot. Figure a little more lube is better than to little. I could be wrong by doing this but I have never encountered any problems. I do use the same oil that I run in the injection system though and it is full synthetic...

I don't believe this is true at all. I've heard it said before but the fact is if your cable breaks, the return spring on the oil pump will take the pump to minimum. I did own a Polaris that had an oil pump set up to default to max with a broken cable but I don't think these Yami's are set up that way. I'm guessing it's spillover from maybe AC, Polaris, and Skidoo that's keeping this theory going.

Now if the guts of the oil pump grenade....I have no idea what will happen.
