So does anybody just mix the stuff themselves? how does it work for you compared to the real thing?

You probably can mix a version. Whether it's cheaper than the $3.70 per quart China-Mart charges is debatable.

It adds about 50 cents per 10 gallons of gas at the recommended dosing rate using Wal-Mart's price (~12 cents/oz).

I wouldn't bother mixing own either, the cost to benefit of MMO is too good to match buying materials separate.

I did find "Sadly" that premium gas pays for itself in the winter since my FE gets moved up back to pre winter levels. It doesn't reduce or increase cost, a wash but I may continue doing it since the 4-8mpg drop I experienced even on my instantaneous MPG during cold weather using e10 is rather disheartening.

rmay, I had to do the same thing 2 winters ago. When I was up in Buffalo visiting family this past holiday season I was using MMO at ~double the recommended dose. It had the same effect as premium in bumping FE. The cost was around $1.75 per tank, or a dollar or so less per tank than 15 gallons of premium based on the current price spread of about 25 cents/gallon between premium and regular.

...I treat my motor oils just like I do my OTC medicines, if I can't read and pronounce the ingredients listed on the labels, I don't buy them (wink,wink)!

My Probe was a Craigslist cheapie. It smokes horribly when I start it (valve seals are shot) but I will not sink money in that car. It was horrible- 1 minute of smoke and it did not smoke at all after that. Now it is better.

I took it in to see how long it would last and get an oil change. I do not know what they put in the oil; but now I start it, get a cloud of blue smoke for about 15 seconds- and have no obvious tailpipe emissions all day.

I do not have any oil pressure, but that Mazda engine seems to like it.

[99LeCouch]

Glad to hear it worked for you!

I've heard lots of good things about MMO, far too many to discount it as a snake oil. Well, it may well be snake oil made from baby garter snakes. I do know it's quieting down my car's fuel system, and reducing knock in near-freezing temperatures. Those are the two objective measures I have at my disposal to know it's doing something.

YMMV...

I use it and STP red bottle every other tank. Going to try 5oz of STP and 3 oz of MMO. I was running a whole bottle of STP and 4oz of MMO but seems to be bit much. Have it in my Festiva now and it's smoking on startup. Didn't do it before and smells like carbon since it's leaks oil like a sieve don't know for a fact though. You could tell it needed a tuneup before but now runs like it had one. All the additives in the world don't replace a good tune-up! Don't know about gas mileage.. most of our trips are city.
