All it does is increase the vicosity of the oil. Inappropriate most of the time and a waste of money. Possibly harmful to your engine.
Is there a problem you are trying to solve? If not, why would you even bother with this stuff?

Hi thanks for the reply, im not trying to address any issues with the lucas ( i wish my leaky front seal could be solved with a bottle of lucas ) I just found a bottle i was going to use on my 2000 f150 before i got rid of it, and was wondering if i should use some on the superduty.

I put the gear oil version in my motorcycle axle gearbox and there was always foam coming out of the vent......I guess if you can get the additive to foam up like washing machine soap its one way for all the internal components of maintaining a surface oil film.

The super duty is def going to the dealer. I have the esp on it. Crazy how a 46k eng can have a front seal leak. Anyway, new engine design i guess... The 120k was my old f150. It was a great truck, i used lucas in that one.. v8 triton.. it ran like a champ, and quiet..but unfortunately the body corroded.i actually miss the ol f150, less technology to go wrong. My 22 superduty has had so many problems.
Strange that some of the 7.3 had front seal leaks, but its better than a rear main that requires a lot more labor to change that one out.

It is actually nothing but super heavy base stocks, no additive of any material kind in it. It is utter and total crap only useful to keep a POS motor from completely falling apart or to get an extra season out of pappy's old lawn snapper. It is 10 times as resistant to flow at 40 weight engine oil. It masks noise and pumps up oil pressure due to its shear viscosity alone. That is why people claim it help them with their uncles friends neighbors dog walkers buddies roommates old Chebbie... it is a bandaid. They make neat little display that 7 years like to play with at the auto parts store.
Can you tell I don't care for it?

Since I have a "fleet" of old trucks, some of them with tired engines that leak, yes, I have used it on them to prolong their life... however with the new engines, the tolerances and specified oils are much thinner, so I definitely would NOT use it in anything newer than say 2002-ish. It is a band-aid for worn out engina's and buys some time if you're not ready to do a rebuild just yet.

Nah...quit beating around the bush, and tell us how you really feel.
for that chart to mean anything, need a side by side with regular gas/diesel oil.

Just a scant 7.54 times thicker than the most common 5w40 out there... were taking the viscosity difference between fresh veggie oil and slightly warm honey.
