I faithfully use Lucas heavy duty oil stabilizer at every oil change as I have heard good things about it. What other Lucas products would be recommended.

I'm having a tranny flush soon so I am wanting to know opinions of the tranny treatment???????

I use Lucas as well. I first used the tranny fluid in a 91 Escort that slipped massively between 1st and 2nd (car had 176K on it). Put the Lucas in, and the problem was solved. In fact, I just put it in the Rivi, and noticed right away that part throttle shifts were smoother, and it largely cured the stutter on the 1-2 WOT shift.

I personally say use it.....I have had nothing but positive experiences with it.

I am still skeptical about their products.. but I wouldn't put anything in my oil. It really isn't necessary. I put in some Seafoam in my oil.. and I don't see how it did anything. Although I didn't see any sludge or any oil build-up on my heads.. so I don't know? The tranny stuff, I am curious about that, mainly because my tranny needs all the help it can get. Anyone else have some opinions on their tranny stuff?

Frankly IMHO those additives are rubbish. It may climb gears on those little displays at your Local Parts Store, but it causes oil to foam and get air in it.

Some tranny additives are worth it, and fuel injector cleaner is good every now and then. But if your motor oil needed it, it would have it in it already.

Would you suggest it for someone like me who'* tranny is probably out the door? I agree with you on the oil additive. You don't need it.

Willwren likes transtune i believe, and it saved his tranny a few weeks on a slushbox that had no edges on the gears left.

This same topic came up on another forum that I am a part of (genvibe.com), and that bob the oil guy is biased to say the least. His testing method seems alright on the surface, but he leaves out a lot of information regarding the parameters of the test. In the pics, he has a couple of gears together and spins them to some unknown speed. At this speed, the Lucas is shown frothing.

First off, I'd be willing to bet that the speed in that test is around 10000 RPM, if not more. The thing to note here is that nothing in our cars (except the */C) spins that fast. Naturally, if you subject something to an enviroment for which it isn't designed, it will fail.
Secondly, Lucas is an ADDITIVE, meaning that you would never run just pure Lucas in your motor and tranny.

The reason that I say stuff about this is that I am a Nuclear Engineer, and I have seen all kinds of lubricants for numerous applications, so I have seen firsthand what happens when you put the wrong type of lubricant into a machine. THis Bob character seems biased at a minimum, if not more, and I think that people should know.

Like I said earlier, I have used both the oil additive (in my old Cobra....which I would routinely run to 7200RPM) and the tranny fluid with great results.

Just my $.50

Greg,

Glad to have you with us

Some additives are absolute dogmeat. They ruin the reputation of all products in the market place. Some have value, nonetheless. Lucas wouldn't have the reputation and credibility they have today if they were junk. Can they save something on it'* last legs? Sure. I've seen the benefits personally. Can they lengthen the lifespan of a mechanical device? Impossible to prove, having no way to compare to identical engines without a HUGE sample size.

me and my dad have added Slick 50 which is made by Lucas to my Bonne for years, and it hasnt hurt a thing. actually, it has helped.

BonneMeMN: Transtune is made by Seafoam, and I too have used it with great results.

GregL: I am glad you pointed that out, I think I am going to give it a try once my engine is running again. Frankly, my Transmission needs all the help it can get.
