Hi,

Yeah, this is silly. I didn't notice a thermocouple or heater in that experiment. I'm silly.

Maybe all that clouding (is it really foam?) goes away with a little heat and that is why it was never seen in the field? That color looks like the water oil mix in my Diesel Rabbit. Could this be two fluids that just don't mix and make an emulsion?

Now I'm confused, I really wanted to run this in my trans to get rid of my early morning grumble at startup. Right now I pump the clutch a couple of times and the grind (while in N) goes away. I suspect it is a dry bearing or gear teeth that needs to be splashed.

As for experiments on Blow-by, you really need to measure it with a flow meter to know it has really gone down (try the NTK M100 ).

Cheers,
Yoko

i have used the lucas many times in the oil. my farmer mechanic friends swear by it and they have a lot of experience with hard working diesels.

i have had no problems with it that i know of but no dramatic cures either. i dont see what harm it can do and the whole foaming discussion seems frankly a little silly.

the reduction in oil consumption sounds possible if the planets were aligned properly (meaning that coditions would have to be just so) but a 5 mpg increase in mileage sounds like more of a freakish thing of slightly altered driving habits and filling under slightly different conditions than something that could be counted on.

i am in agreement with the above post that says heavier oil in a worn engine is good, or lucas oil conditioner or similar. not heavier than is recommended though. just push it toward the heavier end of the recommended oils. as a rule i have always erred on the side of heavier oil.

i do remember once, though, that i couldnt start my bmw motorcycle in the winter til i drained out the 50w and put in some 10w30. i have also gone to lighter oil once or twice in the winter in my cars when they were reluctant to turn over.

After it leaves the pump, much of the oil is sprayed from nozzles. Also, moving parts, like the crankshaft, cause significant agitation of the oil. There is plenty of opportunity for foaming to occur. The fact that engine oils contain anti-foaming agents would tend to confirm that possibility.

You are aware that this claim is a 40% increase in fuel economy by adding a ratio of 1:200 of this fuel conditioner??

Sorry, but it's simply impossible.

it may be impossible,..( i think so too) but i am def going to try some!

Well, document the results carefully. Fill the tank all the way to the filler pipe each time, so that you can see the fuel, after the foam dies down completely.

Make sure you get a decent run out of the tank. 20 cold starts will skew the results unless the test conditions are identical for the second half of the test, which is almost impossible.

Can't say that I do.

But, I know quite a bit about fighting for a lousy 5% increase in fuel economy by attempting to use all kinds of expensive engine controls.

If 40% was available simply from the use of a miniscule amount of additive, it wouldn't be sitting on the shelves begging us to use it. The manufacturer of the engine would specify it's use on a daily basis.

BTW, I may not know much, but I do know that it's Cummins.

where is it that you can run 100 with a semi?

running 100 means running a lot of black smoke for extra power?, no i guess i dont speak southern doya... the running 100 is with the fuel turned up to what, 100% of what is available?

I've seen a multitude of these rigs all over various highways in the US. None of them that are newer than 10 years of age emit any smoke whatsoever out on the highway, even when pulling a large hill.

If the pumps are turned up to send more fuel than they can possibly use, there will be an ample evidence of black smoke. But, contrary to your statement, no additional power will be produced. Without sufficient oxygen, you can't get any horsepower out of the fuel.

An additive can't change the mixture ratio, sorry to tell you.

Just a reminder I have a few hundred cans of slick 50 on sale for $35 a can right now. You might want to look at this thread which is pertinent to miracle automotive additives that are snake oil and what few actually work.

How about you post some testing data.

When you filled the tanks?

How far you travelled?

The route of travel?

The load in the trailer?

Exactly how many gallons of fuel were added after the trip?

Did you fill the tank right to the cap prior to, and after the trip?



Then, a similar set of data for the events after the addition of the Lucas.



Nobody is going to believe you achieved 40% increase in fuel economy by the use of 1 gallon of fuel conditioner. Maybe if you drive the truck around town and you use the fuel gauge as the measuring instrument............but........with real world data...........and a proper measuring technique.............there is no possibility of a 40% fuel economy increase.

Lucus is a waste. All it does is make your oil thicker and reduce aeration. Both keep the oil thicker for longer.

If you want to have great oil use synthetic from the start (Mobil Delvac 1/ Truck and SUV), keep it at the right level, and make sure your oil cooler is clean.

It's all snake oil.

Yep, that's some data that we can all agree is very convincing.

And, BTW, if you start out at 5 mpg after your "power adjustment" and then add the conditoner and the result is 7 mpg, the difference is 2 mpg.

My rule of thumb is to use Lucas when there is a mechanical problem that is starting to show its ugly head. Otherwise I always run Amsoil. I really like the Lucas products, but only as a way to make the equipment last a little longer before bringing out the wrenches.
