Oil Additives: Lucas oil additive, the one at autozone with the spinning gears
the one with the oil additive definitely spins easier.
what do you guys think? hit or miss?

the display isnt meant to show that it spins easier, it doesnt really spin that much easier...
what it shows is that with the additive the oil "wicks" up all the gears and lubricates everything, not just the gears that are sitting in the oil.

Didn't work in the transmission of my father's Dodge Dakota (manual)
and I read bad things about it somewhere. I told my dad not to use it, he did anyway, and now the shifting sucks....the trans is shot anyway though.

Tackifier is something you find in gear oils. Like most things, more is not better.
iirc, it's throw vs tack. Engines depend on splash lubrication, not enough throw means insufficient splash lube. God only knows what cheap additive Lucas adds to their ****ty base oil and what it does when heated and sheared. Not to mention cold-flow. Boneheads put it in and because their engine is smoother/quieter, they think it is better...it's just thicker. Could have started with a fully formulated heavy motor oil and gotten better long-term results. If you want an oil additve, Valvoline SynPower Oil Treatment or MaxLife Engine protector. VSOT is better than MLEP, lots of moly and calcium. If you want cling/tack, try an ester oil like German Syntec, it crawls out of the container (true) and or something like Castrol Start-up or even a Hi-Mi oil.

thanks for the advice, saw bad stuff in the search about it too. guess its a no no.
it apparently traps air in the oil. and oil has a natural additive to prevent this, but the lucas additive throws it off.

More on aeration in lubricants...
I reviewed articles from the SAE conferences on powertrain and fluid systems in Tampa, Fl of October 2004 and the Paris 2000 conference. See SAE SP-1894 and SP-1550. Here is an excerpt:
A New Method of Measuring Aeration and Deaeration of Fluids, Morgan et al:
Air in oil causes oxidation, wasted power, higher oil temperatures, loss of lubricity among other adverse effects. Higher RPM increases aeration, so does *increasing oil viscosity*. (Just FYI)
