oil question

so you are talking about running the oil injection system, which runs at like 32:1ish. then premix your fuel at like 32:1?
if so, your fuel will be mixed at like 16:1 going into the motor. super rich. plus premix oil and oil injection oil are different. not a good idea to ever do this.

Because my dad is telling me that we have to run it like that because he had a boat motor rebuilt and it was a 2 stroke and and they told him to premix and run the injection just to break it in, he won't unhook it until its broken in, what I'm wondering is what is it going to do to the motor? The most it would do is foul the plug, I'm not gonna be running it like this forever, just to break it in. But tell me all of the consequences of doing this if there is any cuz then I can show my dad
Premix oil and oil injection oil arent different.
I run the same sh*t in my Blaster as my girlfriends uncle runs in his. Hes always had oil injection and his blaster is the most reliable quad in the arsenal. It just keeps going.

all oil is different. none are the same.
but by running both, you will foul your plug super fast, it wont run too good at such a rich oil:fuel ratio. and you are wasting money on oil. plus when you increase the oil:fuel ratio, you lean out your air:fuel ratio.
so by putting too much oil in there and not rejetting it, you could blow your engine from running it too lean.

2 different questions/statements in this thread.
To answer the OPS question NO. Dont premix and run injection. Do one or the other.
As to what sheeblast said, its incorrect. You do not buy special oil just cause youre oil injected. Go to a yamaha dealer, tell them you have a blaster with oil injection theyll tell you to run 2S or 2R 2 stroke oil. Tell them you premix. Theyll recommend the same stuff.
Why would the oil be any different? The physics dont change once the oil hits the engine, its all in there for the same reason.

go get two 10w30s, unless they are the same brand, they are different.
no two oils are the same. and it isn't physics that would change, it is chemical.
and actually they make premix oil and injector oil. reason for it, oil will break down in gas over time, so it is designed to resist this.
Is sheeblast right tho by saying that I would run lean on gas and air if I do this? But if so shee I'm only doing it for a break in which doesn't take long to do so, its not gonna matter much by running it lean because I know you can break in a motor when its lean u just have to make sure you don't run it lean any longer than that
You want to break the engine in the way you intend to ride it meaning, if youre premixing, premix. If you dont, dont. Dont do anything special with your oiling/fueling for a breakin. Dont overthink this.
Like I said its getting broke in that way I can't make my dad change his mind, so its gonna blow. The only reason my dad is doing this is because when he had a boat motor rebuilt they told him to do the injection and premix for the break in so he thinks we should do it to this
Then let your dad deal with it dude. Nothing is going to deter him from it.
There are more questions, like, why did it blow up and require a rebuild in the first place? If it was from running lean and getting too hot, your dad isnt doing you any favors by leaning our your mixture.
But, if you cant convince him of it youre just gonna have to roll with the punches.
Heres one bit of info you can use. The stock oil injection system runs a ratio of somewhere like 20:1 or 24:1. Thats quite a bit more oil than the 32:1 that is considered "normal" and some guys even mix 40:1 and 50:1 depending on the oil.
So, the stock injection system, if functional provides plenty of oil for a breakin, or regular riding, as long as it works properly. If the injection works, I honestly dont see any reason why to premix and use it.
But whatever. If he wont listen, then its his deal, ya know?

Well ihes gonna call a shop later and see what they say so if they tell him not to then he's not gonna so I guess we will see, but when I put all the jets in and the reeds and the pipe I obviously was pouring more gas in and my dad thinks that it was the oil injection that blew the motor because when we are adding more fuel but we didn't do anything to add more gas so he thinks that was the problem but idk
i think you meant to say you were adding more fuel but you didn't add more oil.
and the oil injection adds the same ammount of oil to the system. with the oil injection working correctly, you wont blow your engine ever. it put more than enough oil into the engine. and you really aint dumping a lot more fuel with just putting reeds and a pipe. maybe you didn't have it jetted correctly?
Well I still gotta break it in to do a correct plug chop so I'm gonna have to run it lean if its not jetted right
Then just tell your dad if he thinks it was oil injection failure, then remove the injector pump gear, get a blockoff plate, and do it right.
Point is, use one or the other. Dont use both.
