Lucas Upper Cylinder Lubricant?

[SpudRider]

Has anyone tried adding Lucas Upper Cylinder Lubricant to his fuel? Here is the link to a description of the product at the Lucas website.

Walmart sells it for $3.83 in the smallest bottle (5.25 ounces).

Walmart also sells the quart bottle for $8.87. This seems to be the best value.

Thank you for posting this Spud!

Gerry at CSC highly recommends this product during break-in periods on all of their motorcycles. I bought a pretty large bottle for that reason and have been adding it to every fill-up in all of my motorcycles.

2LZ,

What is your assessment of this product after using it? I am tempted to give it a try, myself.

In all honesty Spud, I think it does make the RX3's easier to start after sitting for a week or two....but other than that, I'm just hoping it's quietly doing something good in there. I'm concerned about the intake valves and I'm hoping that running this may help stabilize valve adjustments by lubricating the seats.....or taking the place of lead.

At first I was measuring every shot but after I read that you can't over-feed your bike, I just flip the bottle over and squeeze. "Close enough".

As I've stated prior, I'm not a believer in "Miracle in a Can", but it has to do something. Why would Gerry recommend it if he has no stock in Lucas?

back in the day ,I had a car mechanic tell me he ran a quart of ATF oil in his gas tank every couple of thousand miles just to lube things up and thought it help motor last longer and run smoother. FYI ,YMMV ,CAVIAT EMPTOR, and all those other here to for warnings. I believe him, it was before the internet. rj

Here's my 2 cents. I have a jug of Seafoam in my garage. I use it to treat the gas before storage of everything I have. The main thing I use it for is cleaning the internals before an oil change of my car. My use started when I had an Isuzu Amigo (my little friend). There are certain years of the Amigos and Rodeos that had too small of holes in the piston oil rings in the V6. They become clogged easily and the vehicle starts using oil. I found this out after mine was using about a quart every two weeks or so. Checking forums lead me to Seafoam. They said to add a 1/2 cup or so to the crank case, drive for 20 minutes or so, and then do the oil change. I tried it and the problem went away and I've been a user ever since.

I haven't looked at all the tests that Spud has posted but the Seafoam one did show some improvement. There are other procedures where the plugs are pulled and the stuff is poured onto the tops of the pistons. This cleans them off also.

My father (he was a mechanic) used atf to clean out the top end he poured it in the carb while reving the engine want to talk about some smoke.

Used to do the same thing back in the 70's! You could stop traffic with that smoke! Unreal thick......and it stuck around....

If you are doing this for lubrication and cleaning properties, the old timers in the Goldwing world (and myself and many others) use Marvel Mystery Oil or Stabil Marine (has lubricating properties and better protection against condensation) and swear by it. 2 ounces per 5 gallons of MM0 is all it takes to keep the 4 very finicky and intricate Keihin carbs working perfectly and prevents their teeny tiny internal passages from getting clogged up (a common issue on GL1000-1200's). A 32oz bottle of MMO is around 4 bucks, and lasts for 16 fill ups - or 80 gallons - on my Goldwing.

I recently switched to Stabil Marine 360. It's a little more expensive than MMO, but it has made a huge difference on any post 1+ week storage startups (back to those teeny passages of the GL carbs). It also helps with ethanol blend fuels as well, and only takes one ounce per 10 gal.

I put in a shot glass full every tank...when I remember...

It feels oily to the touch, so I feel it may be more of a lubricant than a cleaner, but that is speculation.

I don't think there is any way to prove if any of the additives are beneficial as far as engine wear, without tearing down the engine, taking measurements, and then comparing to engines that have not had the additives.

You're welcome to tear down my engine to check.....

JB & 2LZ,

Do you guys notice any difference in fuel mileage and/or engine performance when you forget to use the Lucas product?

I bought that additive just because it was recommended by CSC during the break in process. I put in a tiny amount when I was shutting the bike down for the day. The next day the engine kept stalling, about 3 times within the first minute of starting the engine. On the 3rd try I gave it a little throttle and that seemed to stop the stalling while idling. It stalls no matter if the engine is cold or warm. Usually after sitting for a few hours. There have been a few times when I've been coasting at low RPM's when suddenly the engine cuts out.

I didn't start adding the fuel treatment until about mile 180 or 2 visits to the gas station. Recently, at around mile 275, I added a larger amount of the same treatment to a full tank of gas and noticed that It's not stalling as often. Maybe the fuel additive that was added initially by CSC was getting too diluted and not as effective after subsequent fill-ups?

OK I can hereby now vouch that Lucas Upper Cyl FI cleaner wasn't the problem. Things are working normally on the bike with the proper amount Lucas added to the gas tank.

I haven't noticed any difference in mileage or performance.

I keep track of every tankful of fuel. Mileage depends more on the use of the throttle and the terrain.

As much drama as I have had with the engine, it starts with the first push of the starter button, never stalls, and has the same power/performance as it did when new...

....in fact, it seems to be running better....except for the strange noises.
