Thanks for your help guys https://www.nopistons.com/forums/pub...>/bigthumb.gif

I add about 1/2 oz. per gallon at each fill-up, but I still have the stock OMP system hooked up and functioning. It just seems like a little added insurance. At first, my rear bumper was turning black, and I thought it was the extra 2 stroke oil I was adding. Turned out to be a faulty O2 sensor. Installed a new O2 sensor and the black bumper problem went away. I put 100K on the rebuild this way and gas mileage was 24 highway and 21 city. IMHO premix is a smart move.

I have an s5 motor and turbo swapped in my car, and the previous owner was premixing it every other time he fills up. I do not know if he had the OMP removed/disabled or not but I read the electric is not that reliable compared to the s4 mechanic ones. Should I just disable it and start using premix everytime I fill? (if its not yet removed)



I live in canada and the metric system is kinda different than the US.

but with every full tank of gas, I only get about 270Km max, and its empty again. If you guys can convert that to your guys's metric system, what would that be?? I am too stupid to do the conversion, haha I think i did, but the numbers I got was hard to believe...



Anyways, besides all that, the many of you running premixes, what kind of MPG do you get? Turbo or N/A. I need to make this thing a little better on gas.... Im filling it like every 2-3 days... premixing it gets kinda annoying when using the jerican lol..

I heard about a guy in Florida who makes a mod that uses the OMP to draw 2-stroke oil out of a little tank, and send that to the oil injectors, instead of engine oil.



How viable is this info? Is this even possible?

yes here the link for the adaptor you have to use

you will also need a contained to hold the premix

here is another link that needs more work but you dont need to spend money on the adaptor

Hello everyone, Im new to this forum but have already found alot of great info and it seems like a really good community to be a part of. I was reading this thread about the addition of 2 stroke oil to the fuel and I have a few questions if anyone could help me out. First, I am assuming that the addition of the oil helps preserve apex seals and overall support of the rotating assembly. Any other points to doing this? Also, I know that these motors run a little warmer anyway, but with the addition of this oil does anyone recommend (tried) stepping up to a warmer spark plug for self cleaning purposes (prevent fouling if this is an issue?) Thanks

running premix makes the engine more reliable and last longer. The stock oil metering pump (OMP) can fail, resulting in unsufficient lubrication to the rotor housings. The OMP in most cases already doesnt supply enough oil to the combustion chamber, so adding premix in addition to the OMP or just switching to premix all together will guaruntee that the engine is sufficently lubricated. And alos if you completely convert to premix then you dont have to worry as much about the oil level in the motor, which needs to be constantly checked when relying on the OMP (although its always best to regularly check your engine oil level). I have never had a problem fouling plugs while running pre mix, just stock plugs have worked fine for me when running 100:1 premix of Amsoil Synthetic Premix.
