Lucas oil additive is it worth it and what does it do on the inside.

I am sure all you truckers out there have seen all those gallons of Lucas oil additive and want to take the best care you can of or your diesel engine to achieve the highest mileage out of those bearings and moving parts right? I mean who wants to spin a rod or main bearing.

Here's a tip from my actual experiences with Lucas oil in the diesel engine with my hands and eyes.

This tip is going to shock all you truckers!

In my years of experience and seeing hundreds if not thousands of bearings, rings,camshafts, and gears I have been able to tell if a motor of over 600,000 miles has had Lucas oil in it on a regular basis.

You truckers are probably thinking i am crazy right How can i do that. But I prove it every time to truckers and my collages and have not been wrong once in years when a motor gets tore down and i start checking over the parts to make a list of parts needed I always check the bearings to determine if and how much polishing I am going to have to do the crankshaft.

You should see the truckers or owner operators Expression when I have a bearing in my hand and know no history of the truck and I say to the truck driver you use Lucas oil don't you?
Its a look of shock and I always get the reply how did you know that?
So I hold the bearing out and show the driver the wash out on it and I always get the same reply again. That's what it does I thought it was supposed to help the bearings out. But the bearing is the prof. It has a groove in is and you can see how the diff types of metal on it look it almost looks like its is kind of a flaky material. like the bearing is pealing instead of wearing. The metal looks gummy and rolled up it will have small holes all over. If it has had 2 gallon treatments at services of Lucas it will have a large washout in it.

What is the one thing all engine manufactures say about high oil psi? They give you a PSI range and say do not raise the oil psi it will wash out the bearings over time. Cummins said it thousands of times back in the day when people were comparing small cams to the other engines like cat, Detroit, mack, oil psi to cummins they said it had plenty of oil psi and it would wash the bearings if you raise the PSI every type of engine manufacture in the world will tell you this about their motor still today especially. I do say that I do have a harder time determining if a cummins has had Lucas oil in it because they run a lower oil PSI. But i still find the material having the rolling pealing and flaking material look in it and the bearings are a darker color.

They call it liquid ball bearings who in their right mind would want ball bearings in a oil suspension reciprocating parts engine. If the manufactures wanted that they would of made the engine with ball bearings not smooth type bearing they paid money and done the research and testing and have decided on the quality and grade of oil that will last the best for the most engine life. Its these sticky ball bearings that are rolling around and around your crankshaft,camshaft and lifter rollers and pealing away the good material in the bearing and washing them out .

Turn your outside faucet on and let it leave a Small hole in the dirt and that's how the hole in the bearing looks at first these holes in the bearings I thought they were just bad bearings at first but I came to find out after years of asking the drivers what kind of oil they run I found the mystery bearing termite was Lucas not bad bearings and you can see how it just eats at it like a termite until the puddle of oil that's in it spinning at a phenomenal rate of speed in this hole. It wears and works its way out at an angle to the side and blows out the side of the bearing leaving a river trail for the oil to escape.This means this bearing journal is not getting lubricated properly and I am going to half to get the emery cloth out and polish the journals that had the bearings with the river trail to clean up all the scratches and get the excess bearing material off of the crankshaft since that journal didn't get lubricated well and had material exchange. Then i have to clean all that emery cloth material grindings out of the oil passages in the crankshaft so it don't scratch up the new bearings. This means it is going to take me longer to change out your diesel engines bearing and is going to cost you more in the end!

Lucas is a very thick oil and is sold to help your engine have a dry start up right? Well that's the only way that they can legally sell it for an engine is my opinion. Because I have torn down motors that have sit for months with no oil pan and no oil in it waiting for the driver or company to decide if they want to fix it or sell it to salvage yards. When they decide to fix it after 3 or 4 months of not finding any one who will pay them what they would like and if they decide to fix it I will pull the motor the rest of the way down.If its not a motor replacement needed. I will have oil running out of the crankshaft and every where else during disassemble. I have not yet found one dry bearing that needed Lucas or any thing else to lube it during start up! Unless it was a old two stroke that someone dug out of a fence row or the engine was submerged! Actually if i can i prefer to give it a quick 3 second start without oil in it to sling the oil out so its not running down to my arm pits! and the oil still comes running out everywhere and getting all over me everywhere! The diesel engines have so much oil capacity in the passages in the block the engine would probably drip for at least a year. its un believable how long they can sit and not ever have a dry bearing if the oil pan is on especially.

So answer this how many of you truckers take a 6 month vacation between start ups and need to run Lucas? I bet not one in a hundred thousand truckers need to use Lucas in a diesel engine. We will sell it if you truckers want to buy it. But we will never recommend it if you ask.

My personal opinion as a mechanic i say that if you think you half to run it in the engine put a small blob in the fuel tank before fill ups and run it thru the fuel system that's where I believe the lubrication is needed most.

So my tip to all you people wanting to run Lucas in an engine I say no it creates me more work and you more money and less bearing life. Keep it in the fuel, wheel hubs, transmissions, rear ends, and other rotating parts that actually have ball bearings roller bearings and gears in them to run them cooler longer.
