Love my Lucas Oil Additives...

I'm the kinda guy who checks his mileage at every fill-up. When I use Lucas in the oil AND gas, I up my mileage approx. 4MPG (factoring city/hwy/traffic/etc.).

I assume (yes, I know how to spell it...) it improves wear, as very little "goop" appears on my magnetic oil drain plugs.

As Trav mentioned, I am also concerned about the colder-weather affecting the Lucas.


I'd like to thank everybody that responded to my thread--you all seem well-informed. And you'll be happy to know (especially Jim) that I'm going to quit the Pucas...I mean Lucas...today! I'm gonna drop my fluids today, and run some MMO--just in case I missed a drop!

I doubt I'll be able to convince my friends to stop, but I'll try. Thanks again!


Wow, one day and you all got him to stop using what he was using for who knows how long. lol

It's the "more is better" thinking.

As for Bob's tests, indeed they are what we call "highly cheese". Never liked the unscientific aspects and some of the eggbeater ones are hilarious.


A Klear Gearz differential cover would be an accurate way to see if it traps air.

Something i have found on a Chrysler website a long time ago!!

On oil pressure, experts recommend 7 to 10 psi of oil pressure for every 1000 rpm of engine usage.

7 psi + 6000 rpm = 42 psi
10 psi + 6000 rpm = 60 psi

A guy I know who drag races told me that same thing

and high oil pressure is only a part of the equation.

How about volume? Automatically assuming that high oil pressure is desirable is misinformed.

I messed with those Lucas screw things in parts stores before and wondered why someone would want there oil to climb spinning parts and cling to everything. Have you ever watched drops of M1 fall? They will hit something on the way down and bounce away just the opposite of cling.

I had an xj that got totaled in a car accident. It wouldn't move, front axle pushed into the oil pan, control arms bent, all messed up. I poured in some of this stuff, and it started working, drove it another 80,000 miles.

That's an old rule of thumb, that described the bearings getting enough of a supply to keep functioning.

However, depending on oil port size, length, bends and restrictions, the rule of thumb is essentially meaningless these days.

That's a pretty good all round rule of thumb and has worked well for a general rule with the engines I build. Any thing less than that would not be so good.
