Oh Gawd - ANOTHER MMO thread

Not open for further replies.
for those interested, I got some "Liqui Moly Racing Bike-Oil Additiv" and put 80ml in the motor which is slightly less than what was recommended. I raced this weekend and there was no clutch slippage whatsoever. It was brutally hot in NJ (mid 90s) and the motor ran cooler than expected. Not sure if the moly made the difference.

Sounds good, why not start a another thread about it?

fyi.
There are better choices out there.

I know most of you run gas but if it lowers the lubricity of diesel fuel it has to have the same effect on gas...

Gas has no lubricity, how would MMO lower it? Diesel is a totally different animal.

Oh my word does Donald have a new alias from which to attack MMO?

Diesel fuel and gas are not the same, that's why you can't run diesel in a gas engine. MMO does work as an UCL in gas engines. For me this works out to over 2 mpg in my Jeep. Today's ethanol gas is very "dry" if you will.
 
The strange thing is that a lot of people who seem to have negative comments on MMO are brand new here. That is a strange coincidence.
 
People should use the search engine they'd find these things have been beaten to death, brought back, and killed, again and again!
 
is there a way to delete my own thread? It appears that most posters ignore the fundamental question. I'm sorry I asked it.

You can ask the mods to lock the thread by hitting the "Notify" button and explain why. It seems MMO is a target for a Troll attack today. The board has been quiet.

But is does.
The development of direct injection gasoline engines requiring high pressure injection pumps and the introduction of several constraints to fuel composition, including reductions of sulfur content for enhancing catalyst life and performance, are becoming important reasons for considering lubricity as a key property for gasoline fuels.
The lubricity of ethanol-gasoline fuel blends
http://www.scielo.org.co/scielo.php?pid=S0120-62302011000200001&script=sci_arttext
Abstract

In this work the lubricity of several ethanol (hydrated or anhydrous) / gasoline fuel blends was measured by using a conventional HFRR tester. Tests were carried out at 25°C with no water vapour pressure control, according to the ASTM D6079 standard. According to the results the range of variation of the mean wear scar diameter was small among tested fuels in the range E-20 to E-85, indicating that the addition of ethanol, anhydrous or hydrated, did not impact significantly blend lubricity. The addition of hydrated ethanol (96% v/v) slightly improved blend lubricity in comparison with the addition of anhydrous ethanol. The higher mean wear scar diameters, lower fluid film traces and higher friction coefficients obtained for all tested fuels, in comparison with the typical values for diesel fuels, indicate the necessity of using lubricity additives when gasoline or ethanol / gasoline blends are used in new engine technologies requiring higher pressures in the fuel injection system.

Actually gasoline does have lubricity. Maybe not a lot, but things like this are relative. Leaded gasoline had more lubricity - gasoline with ethanol has less. When lead was removed from gasoline, a lot of vehicles started eating their valves because, without the lead they did not seat as well.

As for MMO, it should increase the lubricity of gasoline, no decrease it. It sure helped some vehicles through the 'end-of-lead era'. And, since most of us use gasoline with a good dose of ethanol, any amount of added lubricity is always welcome.

If you want 'no lubricity', consider LPG/CNG! MMO may become the LPG/CNG engine's best friend.

It was too late for me to edit my post and change it to a "little lubricity", I realized someone was going to jump on that. Thanks for the correction.

My point still remains the same, MMO increases or adds lubricity to gasoline. It doesn't take it away. Diesel is a different fuel which has much more lubricity that gasoline.

As a side note too much MMO will lower octane. It might even foul plugs, although I haven't done that even with 2 qts of it in 20 gallons of gas.

Thing is, you don't actually know that's the case--it's just speculation. It very well could lower lubricity just as it did in the diesel fuel test. That said, it seems what little is published out there on "gasoline lubricity", it appears that gasoline has enough lubricity... Maybe this will be more of an issue with direct injection, but even that is speculation at this point.

I'm not saying it doesn't "work". Maybe it helps some fuel systems by providing a cleaning benefit or something? But claims that it increases lubricity is just speculation.

One note to another post regarding ethanol, the actual tests on ethanol seem to show that ethanol actually has better lubricity than gasoline--but there are a whole bunch of other variables that factor in as well. I think the main takeway is that gasoline lubricity just isn't a big deal.
