MMO appears to have improved my engine!

[TechnoLoGs]

Yesterday, I added one quart of MMO to the crankcase upon changing the oil filter. The oil was still new, it is darkening, yes, but it is not black, rather a nice darker than maple syrup brown and as was put in about 2000 miles ago so just the filter, thanks.

Well.. Within 200 miles of driving, the whole car seems to not hesitate and surge NEARLY as much as it used to, if at all!

I also changed brand and model of oil filter from Motorcraft FL-400S to Purolator L20195. This is on the 1995 Ford Taurus 3.0. Had about 200 high heat and high-speed miles (speedometer pegged and bouncing, as per VSS) - and near the end of the trip, the car was running perfectly. No slips, no hesitations, no laboring.. Dare I say it, for the last half hour, I did not want to shut the car off, rather keep driving it. It ran like new.

The thermostat was also changed, and the level of coolant was more or less purged of air (loosening upper hose, letting some out, re-tightening while engine is running) AND returned to just about its proper 50/50 mix of antifreeze.

What say you, is MMO to thank here?

I have used MMO in our vehicles for more years than I can count and wife and I use in the fuel at the rate of 3 to 4 oz per 10 gallons of gasoline at every fill.

Years ago before retirement lived in Wisconsin and always used 20% MMO in the oil especially during the harsh Winter conditions to aid in oil flow and starting. That was years before the oils that we have today came into the picture.

Between the Ethanol in the gasoline and today's low Sulfur fuels the mild cleaning and extra lubrication of the top end is a + in my book.

The driving for 200 miles at higher speeds probably helped. Not that mmo is bad, but how can mmo in oil cure a cars hesitation?

My experience with MMO has been the following so far :

In oil : No visible difference/benefit
In gas : Smoother idle, quieter engine but drop in gas mileage by about 2 mpg. ( I run only 93 octane, this is in reference to the Acura in my signature ).

So, I have stopped using MMO ( dont like my mpgs dropping ) and switched to Redline SI-1 in maintenance doses. Usually get about 4~5 tankfuls per bottle. I dont do it regularly either, just off and on every few months.

I wonder if a cylinder was fouling, ONE cylinder, and MMO helped blow some of the crud out.

I think you're reaching...most likely the high-speed trip gave it an "Italian tune-up" and the new thermostat plus proper mix and cleanliness of the coolant is helping it maintain proper temperature.

MMO is a good product but it doesn't work miracles and doesn't do it that quickly.

How would adding MMO to your oil help with clear combustion chamber fouling ? This would mean the oil/MMO mixture is getting past your piston rings.

To clarify: If the engine ran more "in range," then everything attached/surrounding it maybe acted better?

Discussing what all contributed to the car running smoither, and not laboring anymore.

I agree with this post.

I just take mine on a drive on the PA NE Extension to I-95 to NY and back.

 

[tommygunn]

as far as the hesitation "fix"...nah I can't see MMO fixing that...though yes, it is a good cleaning agent in the oil...that bit of MMO shouldn't help with hesitation I don't think

More than likely that's the t-stat fix up...what was wrong with it? Did you change it to the OEM t-stat? Warmer? Cooler? I've seen it referenced all over, some people swear by running cooler t-stats others swear by running warmer t-stats...I've always just gone with the standard OEM, but upgrade to the "Super Stat" that has the pre-drilled hole in it, to aide in bleeding the cooling system,etc...

But glad it worked for you, I'm a big supporter of MMO in the gas, oil, and as top off fluid all around (Power steering, atf, oil...)

Everything you describe is temp related. The ECM probably saw low coolant temps and the new thermostat addressed that.
Running the engine at high RPM for an extended and extended period probably had a lot to do with it also.

No oil or oil additive would likely produce the benefits you claim especially in 200 miles.
