Your UCL - Lucas, TC-W3, or MMO

[Spyder7]

Just looking to get a sense, within one thread, of what people are using for a UCL and how well they feel its working for them.

I`m using TC-W3, in a 500:1 ratio, but its premature yet to remark on how well its working. I think it may help free up my sticky piston rings, though if it succeeds at I expect it will take awhile (and need some help).

If you're concerned about gummed up ring packs then Auto-RX may be the best way to go.

Uh-oh....

MMO is cheaper and it does everything arx claims to be able to do, save your money and if you have sticky rings, give MMO a shot in your fuel and oil.

UCL and piston rings are typically separate attacks. Get a baseline compression test done on all cylinders before you add your brews to see if any results are made.

A valve that gets cleaned up can help compression, and so will a ring that lets go of retained junk.

I've used MMO as a top off oil between changes, sometimes it was in there a very long time, not any 500 miles. For the fuel (UCL) i do it when I remember or actually have more than a quarter of a tank of fuel when i get home. Empty tank is a teenager deterrant in theory, but never works that way does it LOL.

I've used MMO, PZ TC-W3, techron, and water injection. None of them were able to clean carbon off the piston crown. I just did a seafoam piston soak over a period of 48 hours and I am very pleased with seafoam's carbon dissolving abilities.

Google: saturn piston soak

Soaking could also help your rings. Even though I've never had problems with rings in my 05 Corolla.

Since you asked:
I won't use Lucas UCL again. And I have used/tried it a LOT!
No perceivable results, and expensive to use.
It's just engine oil with some detergents.

MMO is what I normally use for extra lube and a bit of cleaning.

But for felt results, 2 stroke oil is the best feeling. Smooth and peppy .
Partly because of better ring and valve sealing, and also the 2 stroke oil burns for power production.
But there is no cleaning with 2 stroke oil, so MMO is the norm for me.

Not that I care that you don't use it but it's not "just engine oil with detergents" it's a light oil with an extremely low flash point and only contains a high dose of calcium so it doesn't leave deposits on injectors and this same Calcium dose does mild cleaning at best. (As per Terry)

I have back to back UOA's showing with/without it the only difference is chromium wear metals (ring wear) dropping from 2-3 to 0ppm.

I like mmo as a ucl and as a mild cleaner in the fuel. I have used lucas in the past, but mmo is cheaper.

I use MMO in every fuel fill-up. 4 oz. to each 10 gallons of gas. I like the benefits I get from it as a UCL and mild fuel system cleaner. I like MMO a lot, it works great. I had to use it for a few tanks before I saw noticeable improvements though.
