The short version of this is that there is NO STATISTICAL DIFFERENCE between the data sets. You can run the test yourself here: http://eatworms.swmed.edu/~leon/stats/utest.html

Similarly, you could apply a one-tailed t-test assuming unequal variances. I tested at the alpha = 0.05 confidence level and calculated a t-stat of 1.31 vs. and t-crit of 1.78. Because t-stat is closer to zero than t-crit, the null hypothesis (that there is NO SIGNIFICANT DIFFERENCE between populations) must be retained.

I'm finished geeking now.

Carry on!

Thanks... I just got over the nightmares from the summer statistics class. Passed with a B though.
 
Thanks HardbodyLoyalist,

I had come to a similar conclusion, but was curious if Bror had additional data or had changed his mind. As to your geeky-ness, I don't think that trying analyse data is geeky. It's practicle.


KX 455 ,

Have you considered switching back to MMO-free fuel?

Do you mean am I thinking about not using MMO in my fuel?
 
KX 455,

If the MMO "cleaned" something, then you shouldn't need it any more. It is clean.

If the MMO just makes things work, then switching back to fuel without MMO should cause the same problems as before.

If you keep using MMO, well, I guess you are among the converted believers.
 
Well, Morgs, I've tried the MMO in my new Hyundai, couldn't tell any difference in mileage. Smoother? Doubt it, couldn't tell. It's a new car (05 AccentGT), but I used it in the old Hyundai, 1992 Elantra, 168K on the engine, and received no benefit regarding performance/mileage there either. 5W20, Dino, Syn, 5W30, 10W30, with and without VSOT and/or CD2 SLOB, nothing "feels" different or gives me a verifiable increase in performance or MPG. Yet most everyone here reports all kinds of different effects depending on this or that oil, viscosity, or additive.

Then someone around here maybe Terry, or someone of similar wisdom and education, questioned the wisdom of dumping a clorinated solvent in either crankcase OR fuel tank, and I stopped using it (MMO). I do add a two-ounce shot of Lucas UCL to each 10-12 gallon fillup to butter up the uppers, but truthfully, I'm not "feeling" any difference (maybe I'm just not in touch with my "inner car"
lol.gif
). But intellectually, I suppose I know that the intake valves and upper cylinders getting a little lube on them is for the best in the days of 10% plus ethanol. As wih MMO, the Lucas UCL isn't giving me any extra MPG.

Over time, I expect the little things I do to add up to real benefit, such as my PVC catch-can that perhaps eliminates the need for cleaners (the catch can grabs two teaspoons a week of some kind of brown syrupy gruel that would have wound up in the throttle body), the little shot of VSOT I add when I change oil to reduce friction, and the rotation and proper inflation of my tires. These are real, tangible, beneficial actions that positively affect performance, longevity and mileage.

But sweating out the details of viscosity, dino/syn, solvents in the fuel, or reformulating the oil by dumping in ENTIRE bottles of MMO, VSOT or SLOB? Nah, I'm off that train.

You Morg, you and Terry and MolaKule and RayH, and a few others both professional, and simply well-read and self-studied have counseled moderation in all things additive and I've stuck by that pretty religiously of late, and quite to my car's benefit, methinks.
cheers.gif

Sound advice. I've never used MMO in my OBDII engines ..yet. I did my massive dosing of my minivan just to see what didn't happen. I wasn't disappointed. I haven't done it since the two events. The starting is still instantanious when cold.

I'd say as an occasional ucl it wouldn't be a bad thing. It may keep some stuff clean ..and may clean something up ..but I doubt that you're going to do anything other than maintain or correct normal conditions.

SHIZNITOBIGGITYBIZOMB!! You have no idea how refreshing it is for me to see someone here who understands the concept of statistical significance.
 
I had 3.8 Ford V-6 hand grenade that blew a head
gasket. It MMO in the fuel every tank for two
years. That motor was so clean (No Carbon)
on cylinder heads or pistons it was un-believeable. I have use MMO in everything for
the last 15 years and have never had a fuel
injector problem.
 
I've used MMO on/off for about 5 years. Each car I have owned acts slightly different with it in the tank other then the fact that they each start easier. I've never torn an engine apart, so I can't say how clean they are inside, but I like MMO and it use it in all my vehicles and 2 stroke engines several times a year. When I'm getting close to an oil change, I'll add 8-10oz about 100 miles prior to the next scheduled change. It certainly darkens the oil!
 
Way back in the day, when I used MMO, my plugs would come out ashy and red. I only owned used cars then, so I employed it a few times. I guess it was helpfull as a top-oil, but as a cleaner? I dunno.

Red is from MMT, not MMO.
 
I tried it based on the replies in this thread. Gave my Durango a big time mega-dose of MMO. 1 quart in 25 gallons of regular gasoline.

After about 25 miles, it seemed to have quite a bit more snort than it did on gas alone. Not sure why, as my fuel system should be squeaky clean. I use Neutra #131 often, as well as other known good fuel system cleaners.

It still has its slight ping at part-throttle, but there's a TSB to reflash the PCM to correct this. It's known in the Durango/Dakota world as the "death flash" because it programs less timing and a richer mixture. If mine pings severely enough, I'll just run higher octane before I get this flash done.

All in all, I like MMO. Seems to work great. How or why it seems to wake these engines up is still not totally known to me, but I'm quite impressed with the results so far.
 
I've been using 3-4 oz's for every 10 gallons of gas for the last year and my cars are not pinging anymore. My 92 Escort always pinged in hot weather going up a hill and so far this year-No pinging! I put my pre-determined amounts empty Chevron Techron bottles and then store them in the cars. I can't beleive how much Techron I bought over the years.

Good that is the correct amount that is stated.
 
My first introduction to MMO was from a mechanic in our shop some 35 years ago.This old timer told me to put it in my gas tank once in a Blue Moon and in my oil to.I asked him what is a blue moon, and he said about twice a year and dont over do it.Well i did and it took care of my cars and trucks and me in the pocket.And when i asked him what its made of he said its 70% transmission fluid and other secrets.All i know is it worked for me.
