premixing is bad, etc.
well, i've come to the realization that my engine doesn't like to have oil in the gas AT all. when i premix, my gas mileage DIES. it was like 18-19mpg after i changed my plugs. i added some MMO as recommended and it dropped to like 12-14mpg. i ran a few tanks (2 full tanks) of 93oct through and it went back up to 18-19 again (actually got 25 on the highway). now i decided to give it one last shot and its back down. it think i have to stop doing this. there's no way its good for the engine.
on a more exciting note... i'm getting my PFC installed and tuned on the 22nd! yay! i can finally put on my intake and enjoy all the goodies i've added
anyone else have that problem with premixing? otherwise, just thought i'd share

i'm not concerned about the gas mileage, but for some reason adding something to the fuel which results in a 25% decrease in gas mileage tells me that maybe its not working the way its supposed to... i guess that could just be me thinking i know what i'm talking about though i just wonder if its having a negative effect on my plugs or something ya know? need to pull them this weekend and check them out. only have 5k on them, so they should be good

I run 1oz per gallon. It didnt affect my mileage. If you think about it even 1oz per gallon is VERY little.
personally I wouldnt use MMO, I'd use a good high quality 2stoke synthetic. I use Mobile and Amsoil. They are both good. MMO, is not a synthetic oil and I wouldnt run it.

Hamza 34,
Are you saying you believe the oil injection system in the FD does not provide sufficient oil to lubricate the seals in the absence of pre-mixing? Wouldn't Mazda have adjusted the injection amount to the "correct" value during the initial design of the engine?

well, i got the MMO cause it seemed like alot of people on here were worshipping it in the pre-mix threads... what could the strange difference be then? do you see why i would think it might be the pre-mix based on the use/mpg correlation i'm seeing?

When I switched to premix, I noticed the car ran considerably smoother. A positive consequence of premixing is that you can run synthetic in the crank-case.

Best of both worlds:

Run two-stroke AND use the oil injection. Really, the only down side I sea to premixing is that it'll clog your fuel injectors faster.

"MMO" is short for Marvel Mystery Oil, a very ancient product originally offered for lubricating valve stems and upper rings in piston engines. Here is what it says on the can:
"Marvel Mystery Oil is a product of the highest quality. It is light bodied but higher in film strength than many of the heaviest oils. It is friction reducing, wear resistant, gum solvent, and penetrating. It is heat-resisting and when subjected to the high heat of internal combustion produces, not carbon or gum, but a lubricating residue.
Extreme cold does not solidify Marvel Mystery Oil. It flows at 60° below zero.
Can be added to conventional oils to strengthen them or lend them the characteristics needed for best lubrication. Will prevent sticky hydraulic valve lifters and counteracts harmful combustion residues."
(It may even cure dropsy.)
They recommend adding 4 oz per 10 gallons of fuel.
I had used it for a long time and my engines have lasted long periods, but then I change oil every 3K miles, use Techron, etc, so now that I no longer use it I have no idea whether there will be changes I will notice during the remainder of my lifetime.

so i should occasionally run some fuel injector cleaner through my gas just to keep them nice and unplugged i have 93 (produced in like MAy of 92, is that early enough to change the OMP injects? or were you talking about early FB, FCs... how do ya do that anyways?
