My riding lawn mower was cutting in and out, I would clean and adjust it but it would end up the same. I was going to rebuild the carburetor and I had some Lucas upper cylinder oil laying around so I put it in the gas tank. It runs great now, just as smooth as ever.

I use it in all my gas motors. Don't have any diesels. My buddy runs it in all his gas & diesel engines. Both of us like it. Sure helps lube in tank fuel pumps. That should mean longer life.

I put it in my 2000 F150 5.4 to clean the injectors and it seems to do a good job but my gas mileage drops 3 to 4 mpg. When I stop using it my mileage goes back up. This is just the opposite of what other tel me.

I run a couple of bottles of Lucas UCL through the fuel systems of all my Fords during the warm months of the year. I do it to "keep the pipes clean" as much as for the lubrication benefits. The gasoline sold today is pretty much devoid of any lubricants, and here in CT it's 10% ethanol (that is, alcohol) as well. Considering that Ford prices a new fuel pump for my '98 Ranger at well over $400 (yes, that's just for the part), I'm willing to make an effort to keep the original pump running smooth and strong.

Its quite surprising what the truth is.

Very interesting. That explains why adding Lucas to my gas on my GC 5.9 Limited never helped possibly.

If you want just a lubricant, Lucas UCL is fine.
If you want a lubricant and a cleaner @ 70%/30% respectively, MMO is the way to go.
I was always under the impression that Lucas UCL cleaned, too, but look at the MSDS for Lucas UCL and you will see it's 100% oil. MMO is 70% oil and 30% cleaner. Now, all I use is MMO.

I'm not sure if it's been mentioned, but a tcw-3 2stroke outboard oil is one of the best UCL's you can run. It has serious lubrication and a good dose of detergents and corrosion inhibitor as well to keep things clean. You only want to run it at 2 oz per 10 gal of fuel.

Ecoboost will make all of this a moot point. Direct injection takes away the ability of the fuel to clean or lubricate intake valves, since the intake ports only see air, as with a diesel.
There are already problems showing up with some GDI engines (not necessarily Ford) with intake valve deposits that can only be removed by disassembling the head. Cam overlap allows a bit of exhaust to back up in the intake port leaving deposits. VW/Audi has gone to the very complex and expensive step of having port and direct injection in combination to "wash" the intake valves with a little fuel, but not enough to detonate at extremely high compression, which is the whole point of direct injection.

I dont see the direct injection of ecoboost changing anything in that regard.
