Certainly, as said in another thread, there is no concrete proof it does anything.

Lack of harm does not equal proof of benefit.

Cars have also been driven for decades without using it and run just fine.

We are talking about Scotty here; if catalytic converter gets bad, he already has a remedy to fix it :-)

Actually his remedy has worked for quite a few folks.

Wife and I have been using it at the rate of around 4 oz per 10 gallons of gasoline at every fill starting when the first tank of gas is added onward with no issues or catalytic converter problems for many years and in many vehicles.

it has been used in piston driven aircraft engines for years and years too.

MMO certainly has its uses. I use it to preserve carburetors during storage, and have often dumped it down the carb of a running engine just prior to shutdown to coat the intake and cylinders for long-term storage. I can believe its a safe solvent for slow engine de-gunking.

But why, please tell me why, would anyone put an octane-reducer in fuel on a routine basis??? Light oils of any sort SIGNIFICANTLY suppress octane. As discussed on another thread here very recently, distillates like kersone and diesel have octane ratings in the ~40 range, compared to 87 for unleaded gasoline. MMO petroleum distillate content is certainly similar, and in any concentration that could have a lubricating effect it WILL also reduce the octane rating of the fuel appreciably.

If you check the FAQ on the MMO Website it says:

Q: Will MMO cause any damage to oxygen sensors, fuel sensors or catalytic converters?

A: No. MMO has undergone rigorous testing to ensure the safety of all internal components in your vehicle including highly-sensitive oxygen sensors, fuel sensors and catalytic converters.

Catalytic converters are expensive to replace, so they probably did test in this area.

The most likely 'harm' would be a P0420 CEL code - low catalytic converter efficiency. The problem with P0420 codes (and the whole rear oxygen sensor thing) is that many car companies include the rear oxygen sensor simply to comply with OBDII. They don't use it for anything. If anything burps in the catalytic converter, you might get a P0420 code. It might be something serious but more likely just the quirk of how your ECU is programmed.

Have you ever used it? As an oil or fuel additive? Results?

Except that this was a fuel additive question.

Where do you get this? Have you ever tried it as a fuel additive?

From first hand experience, it reduces carbon build-up on valves - pretty effective in that department. Both your 66 Polara and 69 Coronet might like it.

It's a handy lightweight oil for when I don't want to deal with the smell of ATF (cat pee smell) or use waste oil for something.

I have used it for:
- Removing plastidip
- Putting some in a carb and spark plug well
- Light lubrication

Exactly, I have YET to see any testing from MMO with a certified independent lab test that indicates it does ANYTHING beneficial for a modern motor vehicle.

I challenge MMO to provide us with any SAE certified independent lab results that show any benefits... "crickets chirping..." crackmeup

Not a bad cutting oil for aluminum either. Great for squeaky hinges. And it smells good. I'll use better products for cleaning my fuel system but I don't see a problem using it to "fog" an engine for storage or keep a carb from gumming up over the winter.

Uh oh.... You made the list by agreeing with me smile
