This is one off anecdotal, of course, but I know which one I would use again, and which one I likely will not.


Lucas stabilizer will mask piston slap noise in GM engines. They are still slapping...you just don't hear it. But so will a quart of 40w PYB in a fill of PYB 10w40...try it. I did on 2 engines. But once the viscosity starts to shear the slap comes back.

We had a mechanic the used car dept send trades to that prepped them for the line when I worked at a Honda Dealer. This guy swore by the Lucas Oil additive, he threw a qt of it into an engine that had noise. Funny thing was after the customers had the car a while some found the noise came back after an oil change, once the Lucas came out. I heard the synthetic stabilizer is the better of the two. I don't use any of their products by am familiar with them because of this mechanic I knew.


20w50 will have the same effect. Redline 20w50 Motorcycle oil will quiet even the loudest engines.

I didn't, and don't, use their oil stabilizer.

I used their 5/30 synthetic oil, and would do so again.

also on the nice little lucs stabilizer store displays.......

notice which one spins MUCH faster and smoother....... the one without the Lucas.....

fools don't even realize the other one still has oil on it but does the intended job of the gears/motor much better.....

I wouldn't use Lucas on a newer vehicle that works well.

However, I have seen great results by putting Lucas PSF in failing power steering systems, and Lucas ATF additive in failing transmissions.

However, I wouldn't use it in newer good vehicles because of foam.

I don't necessarily hate Lucas, I just don't find values in them given their pricing and rather aggressive promos...

I don't see a single mention of Lucas UCL fuel add in this thread. As far as I know it serves the same purpose as any other add you dump in your tank.

As an assembly lube, it's OK.

Last turbine overhaul we did, we needed the shafts (60T, sitting on 2 bearings) installed before the lift oil was available.

Lucas did a great job, drizzled down the direction of rotation, once the shaft "cracked", it moved very easily, and didn't squeeze out. 4 rotors, 8 bearings, and 200T of metal, and we used about half a quart of Lucas for about 4 days of re-assembly.

Shafts normally run at 3,000 RPM on 60C ISO32.

I use Lucas UCL religiously. (not on the turbines)


If it's the truth....it can handle the pressure !!!

Timing gears, which aren't submerged are another area of possibility. Transmissions, rear-diffs like Bob's test.

Also, oil pumps can, and DO cavitate. This is why anti-cavitation pumps exist.

I don't see too many vehicles in the sig line with over 300k miles on them. Most people don't keep their cars as long as they think they will. It's that overly optimistic view that leads some to add magic tonics to their vehicle in the hopes of auto immortality. The data on this site and others prove that modern engines well maintained usually last the life of the car. Any attempt to "make things even better" usually just results in a thinner wallet for the owner and sometimes detrimental effects to the engine.

Just like the Lucas thick oil demo at the parts counter, it is designed to dazzle the stupid by implying that your car needs much thicker oil than the manufacturers and oil companies provide.

I did a little experiment last year with my motorcycle where I removed the spark plug and noted the appearance of the piston. I next ran a tank of fuel mixed with Redline SL1, then a tank with Seafoam, then a tank with Lucas UCL which also claims to clean the combustion cylinder. Initially the piston crown had a satin black appearance. After the Redline the carbon was reduced with a few spots of metal reflecting light. Then after the Seafoam the piston improved further reducing carbon by approx 40%. Lastly, I added the Lucas UCL. Now my piston had a sooty black appearance uniformly covering the piston crown.

Even if Lucas does offer an un-needed increase in lubrication, it's negatives outweigh any perceived benefit in my opinion. It is like making your engine simulate being an oil burner. Lucas UCL is a petroleum distillate that has the consistency of motor oil so why would one assume it would burn cleanly without residue. Adding 2 cycle oil may offer some benefits, but shouldn't be needed by most people.

If their products are so bad how did they earn enough money to sponsor the Colts football stadium? Just a thought.....

I don't have an opinion about Lucas, but even Enron had naming rights to a stadium at one time.
