Lucas Question

[borispeed]

Does lucas make the oil thicker, or leave the oil with the same viscosity? It is because I am using Lucas for my Lancer so I am thinking to use a thinner oil (currently I'm using 5W-20 according to the manual) The reason of this change is to save gas.

Why are you using the Lucas? Did you say to save gas?

Lucas makes oil thicker. Using Lucas and switching to thinner oil gets you nothing. What's the point?

Lucas is normally used for an engine with a problem, and it works well for that purpose.

I may have misread the original post. If you are using Lucas due to an engine problem and you want to switch to a thinner oil to save gas then you will defeat the purpose of the Lucas.

I hope that makes sense.

Re: Lucas Question

What manual says to use 5/20?? Everything in mine says 10/30.

Its for his Lancer not a F-body.

Re: Lucas Question

Definitely makes it thicker. Usually used to delay dealing with problems where oil starts seeping past seals / rings etc. If you're trying to decrease your oil thickness, do not use lucas. If you need lucas because of leaks, do not use thinner oil. Also I don't like the idea of running thinner oil to save on gas. You might save a little in the shortrun but when your engine craps out early I think you will have negated many of the gains as far as finances go.

Re: Lucas Question

Thanks guys for your comments. I don't think the purpose of Lucas is only to fix problems, but to make the engine perform better. Using Lucas makes my Lancer run smoother and quieter, the same with my camaro, but I suspect that the Lancer might be wasting a little more gas cause of the thickness of the oil (mixed with Lucas). That's why I am thinking to use a lightly thinner oil like 0W-20 which is also recommended for these cars for fuel economy and more performance. The idea (I may be wrong) is to keep the Lucas properties of stabilizing the oil (running the car smoother and quieter), without wasting gas cause of the thickness of Lucas. After all, 0W-20 is lighty thinner than 5W-20. Remember that 4 cylinder cars are made to save gas. Like I said, I may be wrong in all this.

I am a fan of Lucas products, but if your Lancer was not having engine or valve train issues, you really do not need to use it.

Re: Lucas Question

I use Lucas in both my Built motor Trans am and my 98 Vette. I used in in my older cars as well including my V6 firebird. The cars just seem to run better with a bottle of lucas stabalizer in it. I have never had an issue with any car while using lucas oil ( knock on wood).

My trans am sounded like a sewing machine with the LS1 valvetrain noise so thats why I started to use the lucas and it really helps with the sound and bumped my oil pressure up a bit as well. The Corvette is pretty much a stock LS1 but with adding Lucas to that motor with 77,000 miles it bumped the oil pressure up a bit but I also noticed a little better idle and gas miles.

The stuff works wonders. It gives me some peace of mind as well.
