Whoa!

[green-lantern]

I've never been a fan of additives.

[OBXBoost]

I've never been a fan of additives.

even for your hair?

[green-lantern]

even for your hair?

Nope lol especially the occasional dip in the oil pan when under the car :cussout:

[Mr Faust]

Snap son, looks like I been a fool for adding a quart of that stuff last oil change.

Yeah, I always assumed that additives were snake oil, but here is the final verdict. Wow!

[TwoXist]

I have been using half a quart of Lucas in every oil change, mostly due to my bad VSS. I have yet to have a issue with it. To be honest these are just some pictures. So until i see it myself i am gonna keep using it.

[vroom4]

I would be more worried about a test on bearings than a test on gears. I mean I know it still says something...but nothing special in our case.

[ChargerX3]

Old news, but great news. Dont mess with the chemistry of your oil...period.

[hotGTO]

Lucas is great for specific applications, and they have never been cited for FTC violations.

[x2xtreme360]

This has been known by enthusiasts for a LONG time... but good information to pass along.

[Mikes2nd]

welcome to 1998? :)

show us a picture after you drain a hot engine?

[hotGTO]

The biggest problem I have with that demo is that all he is doing is aerating the oils to see how much air he can whip into them with and without the lucas... most people should know that keeping oil levels at the proper level avoids any such aeration...

[i3igpete]

most people should know that keeping oil levels at the proper level avoids any such aeration...

the level of oil in a spur geartrain can be anywhere from 25-75% of the pitch radius, with 50% being the average. The comparison is just above 50%, so the fill level is correct.

See the effect of fill level, h-bar, on page 64 of the following reference:

Holy Disertation! 100+ pages...Ill have to get back to that.

[hotGTO]

I just don't see how a spinning a gear half submerged like this equates to what is going on inside a full crankcase in a motor, that's my only question... Supposedly when your crankcase is at the "full" level your oil does NOT aerate... That's all I'm saying.

[i3igpete]

That is representative of what is going on a transmission or differential. Much less worse than in an engine. Here you have an oil pump creating vacuum and possibly cavitating the oil on the way in, the high pressure galleries feeding main bearings, which then feed conrods (cavitation is actually quite common here). Either that, or they spin around and come out the sides of the bearing shells after 10-50 spins around and aerating.

[Mean Green]

I run lucas on every oil change on both cars. The Eclipse has bad lifters but with the lucas, you cannot hear them...with just Rotella, they sing in the morning. One thing that that guy is not testing is heat in engines.

Neither had Enron or Lehman Brothers!

LMAO! Touche! :P

I will still continue to enjoy Lucas products, and so will a lot of others... If it didn't do anything good, or if it did anything bad, those of us who use it and have for years would stop using it. That's the bottom line. No advertisement or store display gimmick turned me on to lucas, it was a mechanic, and word of mouth from people who use it is almost always that it is good, almost never that it is junk... So, I understand the theory behind "You should never add anything to your oil." But that broad statement does not always apply in every case...

Listening isn't your strong point.

Ask me if I give a rats ass what you think.... You will love the answer

[i3igpete]

do you give a rat's ass what i think?

Spoken like a true NoOb. Good luck with that.

Yes I do

Once again, you have added another post with zero value! This is not the first time you have quoted me in a thread for no reason other than start drama, so you can name call all you want but what you should do is stop referring to my posts if you have nothing valuable to say. Until you do, I don't give a rats ass what you think.

[spraynpray]

look i have been using Lucas products for years in both my street vehicles and my racing vehicles, i have yet to have any bad outcomes due to the lucas line. i believe they have done enough R&D on their product to minimalize or even delete any problems that may arise.

Just like all the other gimmick products that have done "R&D" on their products? Oil additives are not desirable.

[spraynpray]

i dont think you can say Lucas is a "gimmick product". they are the one of the largest oil additives on the market even hosting a drag circuit. I believe if it was as bad as you say it is they wouldnt be able to accomplish as much. Understandable, everyone has their own preferences but i have had it in a bike that i have had to 175mph and as soon as that run was over i tore it down and all internals were fine. I just dont think this "test" is conclusive sorry

[hotGTO]

Who ever said Lucas oil products were gimmicks? They are not making any "slick 50" or "Restore" claims or any other crazy advertising... It is simply a good line of oil products like any other line of oil products... A LOT of people use Lucas oil products and I have never heard anyone say they used it and their motor blew up, on the contrary I have heard a lot of people praise Lucas oil stabilizer in high mileage applications where the tolerances in a motor called for the use of it to extend the life of the motor. People need to stop being sheep!

You beat me to it! LOL

[spraynpray]

lol sorry too slow lol

[hotGTO]

I can put oil in a blender and aerate it...

Don't get me wrong, I am not saying Bob-is-the-oil-guy does not have a lot of good info, but just like every other bit of info out there, don't just believe it just because Bob said it. Bob is not some all knowing oil god, and he had to get his info from somewhere and as we all know all info is not always all correct...

[i3igpete]

i think bob actually might be the oil god.

[hotGTO]

He does know a lot, but he is more opinionated than objective.... that makes me question some of his writings

[Mike-92RT]

i was told only to put in half of the bottle of lucas, then my regular oil... i've never had any problems with lucas.

[J-Groove]

I work for Hydrotex, we have seen very similar results in our labs.

Yup, I would not use this, now Essentialube I do add to engine oil and gasoline. ;)

I'll bug the lab at work tomorrow.

Cool.... Why do you use Essentialube?

OH, nevermind, you work for Hydrotex who MAKES Essentialube which is Lucas' competition!!! NICE COMMERCIAL!

[J-Groove]

Thank you. :)

I personally don't use essentialube because I'm running Hydrotex oil which does not benefit from the Essentialube blending agent.

That is the key thing, Lucas makes an additive, a pour in one at that that you cannot be certain will be compatible with other additive blended oils. As shown in the test on Bob's Oil Guy site the additive did not mix and caused foam.

Lucas does make blending agents, you will want to use a blending agent with any blended oil. The same Lucas oil additive used in the test would be great with any group 1 or 2 oils. The point of the test on Bob's site is to help show why you should not use an additive with a blended group 3+ quality oil.

-John

[hotGTO]

Lucas also makes motor oil, and full synthetic additives, and probably one you don't need the blending agent... You should know all that... When Lucas oil or Lucas additives are proven to cause engine damage, then you can support the claim that they are harmful. Until then, you can't say they hurt anything or that we shouldn't use it.

When the hell did I say they were proven to cause engine damage or that they were harmful? That is a very broad statement. My main point was ...The point of the test on Bob's site is to help show why you should not use an additive with a blended group 3+ quality oil...

You should NOT use an additive without knowing how it will react with your oil's additive package blend. Is it always going to be a bad thing? No. The test on Bob is the Oil guy proved that the additive worked to give the oil a high film strength and allowed it to crawl up the gears. but in the case as the test it also generated a lot of foam. Foam is BAD. So that is not a blend you want to use.

The site is saying use common sense, don't mix something without knowing what it will do.

-John

[hotGTO]

Oh, I thought you were one of the "Don't use Lucas" fanatics who won't actually say its harmful, but act like you are pouring sand in your motor if you use it... I see where you are coming from, i catch what your throwing at me... lol

[coamovr4]

Yesterday I changed my oil and the car started to smoke at idle... I used Lucas Oil Stabilizer like an hour ago and dont smoke anymore.... hope it works.. my turbos are new btw

[jerrid]

I've never cared for lucas but I'm a big fan of z-max, it's technically not an additive it uses the oil as carrier, it makes the cars shift better and run better.

is this just an advertisement to have a dry-sump engine?

[Alex3000gt]

If these snake oils actually worked the way they claim, OEMs would be calling for their use in the shop manual.

But they do not work, the OEMs don't recommend them, buyer beware. If it sounds too good to be true, it is.
