UCL vs MMO

[Shelby]

I'm pretty sure this has been discussed before but which one of these works better as a lube? I had UCL in one tank and MMO in the other, and soon as I switched tanks my motor was super quiet. The problem is I forgot

which tank, front or back, I put each product in. They both work very good as ever since I'm in my ARX rinse phase I have very little engine noise, but one of them works especially well. Which works better for you?

I really prefer the UCL. MMO is weird to me and I wouldnt add it to gas at all.

wow mmo is cheap, $5 for 32oz. I just looked at it online, made by turtle wax. What the heck is it? I know UCL us mainly polyisobutylene.

I've found MMO to do a good job of smoothing out the engine. Didn't notice it with UCL.

I have read this several times, but does somebody have a source for this information? The Lucas MSDS doesn't show jack.

I run it alot. Smoothes the engine out alot. I check my plugs often and see no residue from it. Also the car was using it up till the tank I used on the emissions test. Aced the exam. I use it less now as I have found the car really like Redline. But I think its great.

I think MMO is mostly kerosene. IMHO its only use is in an engine (like a boat) where water got into the cylinder and has rusted things.

IF Lucas UCL is base on PIB, it is not the same molecular weight as the PIB in the GTA product described by psudaytona's link. I would guess that Lucas UCL does have PIB (I know that I am guessing), but if it does, it has to be a much shorter polymer. I have both products in my garage. The GTA product is the consistancy of snot and produces very long strings of fluid if you try to pour it. Lucas is thick, but it is not snot-like nor does form very long strings of fluid.
