Because the OEM'S are concerned that the pump may have air in the lines when first started. I would run alittle pre mix in any injected motor when ever new or after work on the injection pump/ lines.
Extra oil for break in is counterproductive IMO.

I knew there was more to that story..

Would 100:1 pre mix be sufficient for protection through this period?
Surely it would fog less skeeters..

The one with the highest viscosity...800 2T.

yamaha folks were talking about low and high molecular weight polybutene.
low molecular : https://en.wikipedia.org/wiki/Polybutene
the high molecular weight version polybutene-1 is used in polystyrene (styrofoam): https://en.wikipedia.org/wiki/Polybutylene
edit: spelling. what happened to this site?

Brad, you can't say that with any certainty....
Although based in its extremely high metal content and its viscosity 800 might go a little longer. Of course the opposite could be true as well.

KL-200 will last longer??
PIB might be used to make styrofoam and it may not. PIB isn't styrofoam.
Also might point out these negative effects are associated with high levels of PIB and high molecular weight PIB. At the levels found in the two cycle oils I have looked at it simply isn't an issue. And Yamaha itself uses PIB with all of their two cycle oils I have looked at.
Castor oil will beat all of them.
How this relevant to anything?

KL-200 is castor or synthetic? I only remember reading KL-200 had an extremely high viscosity.

read up on the health effects folks. stay safe.
when i first was involved with abrasive blasting of lead paint 25 years ago. the only safety warning required at the time on the collected slag placed in 55 gallon sealed drums was.... "do not eat."

I believe it's their older synthetic.
Viscosity isn't the only thing going on when it pertains to the question at hand.
Castor for instance polymerizes under heat to form a grease like substance, so it has a a film strength that's off the charts.

All this stuff has gotten out of hand. I wouldnt believe any oils claim until Ive seen 2 oils compared side by side in equipment to failure. Anything else is an opinion and a waste of time

Alota the hotsaw guys use kl200. Gotta be a reason

Methanol and Nitromethane. Completely different ballgame.

Even compared side to side in one scenario they're gonna be different in another so too many variables to just say one oil is the best.
Stats being what they are 1 on 1 doesn't mean squat. And there is a reason tests like this have never been done. They don't mean squat or tell you anything about how a oil at a normal ratio performs over the life of a saw.

Bah! Technical papers do not mean anything! They are written by marketing and advertising people and are just hype!
No, I do not actually believe this, but many so called "experts" on this site do. As for this site, it has gone to shyte in many ways from Sunday.
