Pre-mix right away after rebuild?
 

Just wodering if it is best to run pre-mix during the breaking or if it is better to wait untill the motor is broken in. I am still running my metering oil pump but would like some extra protection. Thank

running too much pre-mix is not a good thing. The OMP does a very good job all by itself for street driving (provided it's working properly).

Pettit recommends you do use a premix (namely theirs) when you're breaking in the motor. Then every other tank of gas after that. That's what they told me when I had my motor rebuilt last year.

From looking around, I think Pettit is the only tuner that recommends that stuff.

Actually in japan, the mechanics at knightsports and RE Amemiya recommend pre-mixing too with Redline two stroke oil. I believe the mixture was 100 to 1 for the street and 50 to 1 on the race track or something like that..

Actually, KD Rotary also likes the pre-mix. I brought in a little bottle of Pettit's pre-mix to KD Rotary and Dave said so many good things about that stuff. He said he can easily notice a difference when someone uses the pre-mix when he takes apart the engine. I'm using the Pettit's pre-mix at every other fill up and never noticed any problems at all.

I stand corrected! :)

would it make sense to say "not durring the breakin period"?
wouldnt that extend the period? sort of like you would not want to run a synthetic oil durring the breakin. it would be extra lubrication not needed during this time. you are trying to "break it in"...does this make any sense or is my brain fried from being in work for 15hrs to long today?

You're fried. :) The reason you don't want to use synthetics during break-in, is they are too lubricating and won't allow the seals to wear-in. The pre-mix is not a synthetic, so it will give you just a little extra lube to keep things nice and slippery.

Wow, taken out of context, that takes on a whole different meaning.

rotary reliabilty and racing told me to premix as well....when I got my car back today!

Very true. I use Protek on every fill up, have since the car was new. When I tore my engine apart, I also tore another apart where I was told the owner didnt use premix. To make a long story short, my engine looked almost brand new and took me about an hour to clean everything. The other engine? Well I spent dang near half a day cleaning the other one, and it still didnt clean up well. It was covered in carbon and just a mess. If I had never used it before, that definetely would have sold me on it. I just wish I would've taken pictures of it all.

I premix! Pennzoil TC-W3 marine grade 2-stroke oil. Four to six breaths (chugs, glugs, whatever you like to call them) every other tank. Car seems to start more smoothly, but it could be just a placebo.

actualy it is a synthetic. all protck-R is, is a synthetic 2 cycle oil made by Polaris as a Jet-Ski 2 cycle oil.
and i understand why synthetic are to lubricating and wont allow the seals to break-in. hence my statement about not using them durring the break in period. so would it make a difference if you didnt use this pre-mix durring the breakin period, but DID always use it after...would it change "clean-up time"? (as rx7even put it)

Why every OTHER tank? I could see that for some types of additives or engine treatments that only need to be run so often, but it would seem that the 2-stroke oil only benefits when it is actually being run. If it's an expense issue, even running 1/2 as much every tank would make more sense to me. I could be wrong, I'm no expert, it just seems a little strange to me.
