1. It is more than 80WT. More like 300WT.
2. No Soap
3. It has anti foam in it.
4. No oil has anti foam built in. Hence why you add limited slip additive to Diff oil (All limited slip additive is...is anti foam).

I know what you are referring to about the milkshake, that guy who did that test. But there was only one flaw in that test: It is not done at engine or differential operating temps.

I once drained my engine oil (with 1 QT lucas) right after driving at operating temp for a while. And although I singed my fingers because of the oil being hot, it was not a milkshake. It looked like normal.

I can only go by my firsthand experience on this one. Lucas used in my engine:
1. Never milkshaked
2. My engine is squeaky clean: Probably more because of the previous owner using Mobil I Syn at every oil change and him not adding any engine restore or flush type additives. But after 2 years of using lucas every 3000 miles, it is clean.

 

Let me re-iterate:

NEVER USE ANYTHING IN THE TRANNY EXCEPT ATF+4!!!!

 

what about the z max stuff they have oil additive and fuel additive are they any good?

 

how many miles do you have on your truck? Because, anything under 80K, I would just keep away from engine oil additives. Just use good synthetic 10W40 for your 2001.

 

my problem with the lucas is the fact that it raises viscosity to a weight the engine was not intended to use

 

That is why you use it on higher mileage engines, or older engines. Because it is no longer a "tight" engine. my 1996 5.2 required 5W20 (written on the oil fill cap). After 150K you cannot tell me that 5W20 is good enough for a truck.

 

I dont believe 5W-20 existed in 1996.


Here is my 2 cents on additives: DONT USE THEM! Zmax is snake oil. Lucas is 300Wt oil. Unless you have underlying problems....Wait, if you have underlying problems, fix them, not cover them up.

 

I cant speak for the dodge engines since I have only owned them for a short time. But my Oldsmobile bravada that I just sold had 215,432 miles on it when I sold it. I ran lucas oil and trans additive in it. It carried about 40lbs of oil pressure at idle and 60lbs driving. I bought the truck with 90,XXX miles on it. and used lucas oil stabilizer in it from day 1 of purchase. I changed the oil every 3500 miles. when I needed to change my intake gaskets at 200K I also decided to do the valve covers as well. The valvetrain was incredibly clean looking for an engine with 200K+ miles. So whether or not it works is an opinion. Mine is it don't seem to harm it. I put a litre of lucas trans. additive in my recently purchased ram 1500 5.9L with 100,000 on it. So if it goes out I will let you know. Of course it could be from the 38" swampers and What I believe to be stock gearing too. lol

 

I see your point, but a 4.3 will go almost forever on little or no maintnace.

 

ITS NOT OPPINION, but if you would like to add it go right ahead...

as far as it increasing viscosity to raise oil pressure in worn engines, thats very true and i guess it cant hurt in that situation; however it is just masking the fact that clearances are out of OEM spec
