I used it on GM 5.3 that had a loud lifter noise, Lucas sure helped it quiet down and increase oil pressure

I had a lot less rodknock than that, but I use it every oil change and it has never knocked since. I still run the engine hard and no problems so far. I've done this for 2 years

Definitely quieted my R18 for a day or two, but not really meant for a serious knock from a spun bearing. Had D16Y7, K20Z1, K24Z7, and R18A. The R gave out on me, but I was beating on it and I didn't know previous owner's maintenance.

rod knock means there's a physical gap, noise is friction. It can't fill in the gap, but if it reduces the noise it reduces the friction and therfore slows the rate of wear. It buys you time... but if the knock is that light you should just put a set of bearings in. If it starts knocking with the lucas in it, you've probably ovaled your rods thus now you gotta pull the head... maybe the trans too to replace the crank.

That’s awesome you got a good result hey I have a 2001 Firebird Pontiac fusion 5.7 L we’re not rattling noise I added this on my card definitely made a big difference it’s good stuff oil stabilizer

I think the thing to remember is that its generally a sign of worn or buggered bearings. Bearing oriented rod knock is a disaster waiting to happen. Additives only thicken things and take away the noise, it doesn't fix the problem. I suppose if you have a really old car and don't care about collateral damage to other parts in your engine then Lucas and other type products are ok.

I've been using Lucas in my big block 94 7.5 liter Ford for 20 years. I think it's the reason why it has 207+ thousand miles and still running strong.

I bought a civic for $150 that knocked like CRAZY. I threw 2 bottles of Lucas and drove it for 100 miles before replacing the engine. 330k mile D16Y7

engine still running quiet, how many miles since you used lucas 1st time?

Do a video on MotorKote, that stuff is pretty good 👍🏻

Damn that is amazing!! WTH!! I’m sold!

I have a vw cc. 2.0 tsi... cambridge was worn and so are cams. not terrible wear but enough to lower oil pressure. wear was caused by screen that dislodged in camrbidge. I dont have the money to replace both cams, cambridge, and possibly the head of the engine. to get a few more miles should i give oil stabilizer a shot?

Good stuff and makes a good difference

How's it doing?

Sounds like it could use a valve adjustment too

What kind of air intake is that and how do you like it? Besides the sound does it do anything else for your car like add more power, better mpg or help your engine run cooler? Do you still use it? Any info would be greatly appreciated. I liked the video and subscribed. Thanks!

Man, a whole bottle of Lucas on a 3.8 quarts engine is high dose.

Does the Lucas help with bad rings as well ???

Lucas won't fix the problem, but will reduce the noise and prolong the life of the engine, my friend did an extra 100K with is, and it's still working good.

Got a rod knock in my engine I have a 2002 Mitsubishi Galant yes what's a 2.4 l and the rockmart started two days ago on the Sunday got the Lucas today so hopefully it fixes it

Lucas is the shit. The Trany fluid and the power steering restore Lucas makes also works well

my question is, why not use higher viscosity than recommended?

I think viscosities have gotten too light, for two factors- Overhead cams need lighter oils to lift and lubricate the taller engine and secondly, too many lemmings following racing practices, where they like a lightweight sewing machine oil for top spinning speed, where thick oil just gets in the way. BUT, the racing world is only ever using the oil for 500 miles or so between rebuilds, you're driving thousands of miles and probably generally TOO FAR between changes. All the additive products are then THICK stuff (after the flush at least) to make up for the thin oils not coating well when tolerances are wearing things out. "500 mile" light sewing machine oil isn't lubricating very well then, especially full of grit and gunk. I've had to run a lot of high mile used cars through the decades, and before DOHC I usually used straight 40 and even 50 weight when you could still get it, and NEVER had any internal engine problems up into the 250,000 plus ranges. You have to change the oil on schedule or SOONER though. And if you want thicker viscosities now- here's a tip- mix in some gear oil to boost it up. It doesn't leak through gaskets as fast either.

Did you take out any oil before putting the Lucas stabilizer?

Is ight nun too serious but shoutout to Lucas oil for keeping that engine good 👍 👏 👌 😏

You’ll have to use two bottles to stop the knocking noise , Then hurry up & sell the car

Mys has lite knock from 2-4K rev up after that she ok no noise my eJ1 27 yrs old same engine over 280k miles iam try this this weekend if I can get her last 300k ish “ my 700$ worth investment paid it self off ..I have b20v with Gsr trans stash away in case in she gives up .

Sounds good to me

That sounds way better, just be gentle with her until you can find a new engine or a new car

It is a little more expensive per oil change but still way less than pep boys

I hate additives as a general rule, it it might be worth trying Ametech Restore. Not sure it'll save it but it might help.

will this help wristpin slap ? or piston slap ?

Did you end up tearing down the engine because it got worse?

It probably just needs a valve adjustment

I just bought a 2001 Jeep Grand Cherokee off a guy with a rod knock in it. I can add the Lucas oil to it without having to change the oil out first right? Cause the guy just changed it before I bought it.

Try banana peels from at least 2 or 3 bananas...that will make it quiet

fix rod knock tighten up lifters

for badly worn: up to 3qts of a 5qt change! - says the bottle

rip.

Stab a hole in the bottom of the jug and it will flow out faster 👍

You can’t fix it, you simply mask/dampen the sound...

it will prevent it when you use it normally

lol thats not even mild

Just curious, when you change the oil and filter next time, do you have to add Lucas oil stabilizer every time or is this a one time application?
