Oil Injection or Pre-Mix?

On my jet skis, I always bypassed the injection by default and went strait to a pre-mix. Is this recommended on the 95 Speedster? If I go to pre-mix, is any carb adjustment required? Pros/Cons? Thanks.
 
Pros: you know those cylinder walls are getting oiled, assuming your carbs are all to spec.

Cons: you are going to get a lot more smoke at idle and it's much more expensive to mix 30 gallons of premix when that oil goes for 50 bucks a gallon.

If your injection system is working, my vote would be to keep it. They are super reliable if you keep them maintained.

I've read soooo many posts on here where people convert them back to injectors after they saw it was converted to pre-mix.

That's my .02.

It's all about preference but I think most would say it's unnecessary.

The Rotax/Mikuni injection is MEGA reliable !!!!!!!!!!

People who say otherwise... or try to say... "That dam system killed my engine"... what they really meant to say is... "I never serviced the oil system, and I'm an idiot."


Basically... every other year... I would recommend changing the filter... and every season, check the hoses. If they are questionable... replace them !!!!! If you have a hose rot, and fall off... you loose an engine. (I use Tygon as a replacement)
 
Ok, I will keep the auto injection. The tank is half full of what I assume is two stroke oil. How do I determine what kind it is? If I drain it out and refill with fresh stuff, how do I get all the oil stuff out of the lines without removing them or replacing them? How do I get the oil pumps flushed out? Can you check oil compatibility some how?
 
What color is it? I used one of thesedownload (1).jpg to flush the tcw-3 out of the rotary cavities and get all the air out of the lines. I think $15 at advance auto
 
I ave used amsoil, seadoo conventional (Never XPS Synthetic), Mystik Full synthetic, Quicksilver for PWCs and Sea and Snow for PWCs in the past. None of these are light green. Sorry!

If you not sure just drain the old oil. seadoo's oil pumps are reliable. You can test the pumps with a drill in reverse to see if they pump. Since its all apart I would get new check valves for the pumps.
