Never Use This Type of Engine Oil Additive in Your Car

Never Use This Type of Engine Oil Additive in Your Car


rev up your engines, today I’m going to
talk about engine oil additives and specifically this new Lucas made for low
viscosity oils that modern cars use, now to begin with I’ll give you a general
idea about oil additives in cars, modern engine oils are really well designed and
produced, you buy a brand new car you use the correct oil that they suggest and
change it frequently, you don’t need to put any answers in your oil period, but
if you bought a used car it burns a reasonable amount of oil, or you were a bad
person and you didn’t change your engine oil enough and now your engine has worn
internally, oil additives can actually help, I bought this
Toyota Celica used, and the main reason I got a cheap was cuz it was using the oil
and a customer thought, oh you know it’s wearing out and
I’ll get another car, she went out and bought a Toyota Avalon, she was burning about a
quart of oil every 900 miles in that Celica she had to keep adding the oil,
she had a case in the trunk, I changed the oil filter, put in three quarts of
Castrol GTX and one quart of this heavy-duty thick stabilizer from Lucas,
and lo and behold then it only burned about half a quart of oil in between oil
changes, and not it used half a quart instead of a quart every 900 miles, quite
an improvement I gotta say, but you do have to understand what type of engine
is in here, it’s the Toyota four-cylinder engine, it doesn’t have hydraulic valve
lifters, it’s just got those stainless steel shims, so there’s no hydraulic
valve lifters with the tiny little holes that the oil has to get into to pump up
to adjust the valves, if you add a thick oil like this to an engine that has
hydraulic valve lifters, they can start clattering like mad I’ve seen that, and
even further this is a plain old engine it’s got a solid cam that spins and opens
and closes the intake and the exhaust valves, it does not have variable valve
timing, you put a thick oil into a car that’s got variable valve timing and
blammo, a lot of times it will cause problems in the variable valve timing
system, so you really can’t use this heavy stuff in any modern car, now how thick
is this stuff watch how thick it is, one it
won’t even come out of the bottle I got to squeeze it, and as I do look at it, it’s
like molasses, and we’ll compare it to the new Lucas stabilizer that’s the
lighter oil watch this, quite a difference, now when people tested the
stuff, they found that this old thick formula has a viscosity of 110 when the
oil is 212 degrees Fahrenheit now the viscosity of the low viscosity
Lucas stabilizer is 19.7 at 212 degrees Fahrenheit, that’s a lot less than a
hundred and ten of the old thick stuff now since the new oil is thinner and
look at the size, this thing is only 12 fluid ounces, the old one is 32 fluid
ounces, so not only is it lighter but you’re not diluting the oil in your
engine as much because you only have 12 ounces instead of 32 ounces, so it’s safe
to use an engines that have variable valve timing, that use really lightweight
oil, that have hydraulic lifters, you’re not gonna get problems that you will
from the super thick additive of the old Lucas, now what’s exactly in this stuff,
well if we do a little history lesson go back to when I was a kid in the 60s, the
big oil additive was STP and it was really thick too real thick, especially
when I was a kid up north, boy it was cold outside,
you ready had to heat this stuff up and boil it in
water before you could pour it in an engine if it was outside, now STP started
in 1955, they have a special additive, they
still used to today in their STP treatment and it’s
zinc phosphate it’s an anti wear additive that scientists know it works,
it does lower friction, but it has one major drawback today of eventually
ruining your catalytic converters, know when I was a young mechanic in the
sixties we didn’t care about that, cars didn’t have catalytic converters in the
United States until the mid 1970s, so we didn’t care we just put it in we see
these old Junkers that were clacking and making all kinds of noise and it would
quiet them down quite a bit and a lot of times it can make an old worn out engine
lasts a little bit longer, I remember when I went to a Formula One race a couple
of years ago, I was talking to the engineers and
they admitted to me that during the practice runs they use their old
worn-out engines, they want to use them in the race, they use them then and they
put a heavier thicker oil in their practice runs, so their engines that
were more worn last longer and not blow up as fast, but during the race then they
put in a good engine and they would use the lightest oil they could possibly
have, so that they’d have more acceleration, now Lucas Oil came out in
1989 original formula is really thick just like the STP, but it doesn’t have
that zinc additive to it, so both of these don’t have any of those fancy
additives like zinc they’re all petroleum products so you can mix them
with any petroleum products that are out there, strangely enough it works really
good in standard transmissions, standard transmissions are just splash
lubrication, the gears are inside the transmission housing and the oil inside is
just splashed around to lubricate the gears, as they wear and the space
gets a little bit further between the teeth, they make noise, they can be harder
to shift with your hands, and I’ve seen these things get a transmission that was
really hellacious to drive and made all kinds of noise, work a lot better and
make a lot less noise just by pouring this stuff in, and Lucas also makes an
automatic transmission additive that’s pretty thick too, now you could use it in
the older American cars I had miracles myself when somebody bring me an old
Chevy Tahoe or something and it would barely move down the road, and I’d take a quart
of the fluid out of the transmission and put a quart of the Lucas thick automatic
transmission additive and all of a sudden it started to shift pretty good
that kind of phased me when I did that the first time, I thought how could
something like that do that much, but it did in many cases, don’t you dare try
that in a modern computer controlled transmission, or especially a CVT
transmission, those things have to use their fluid and nothing but their fluid
don’t put any kind of additives in those things, so going back to the
original topic, the new low viscosity stabilizer, you can use it modern engines
that have the vvt or that have hydraulic lifters in
them, now it’s no miracle and a can you know there are no miracles and cans
these days anyways, if you take care of your vehicle, use good oil, change it all
the time, you don’t need to use any additives really, but let’s say your
girlfriend is bad never change the oil in her car, or you got suckered into
buying a late-model car that’s got high mileage and the people didn’t maintain
it, I’d stick the stuff in see what it does, cuz really hey you got nothing to
lose the engine is make a lot of noise and it’s
wearing out, you’re living a borrowed time anyway, and since this is mechanic
Monday I’ll be giving away some of this low viscosity Lucas stabilizer, to have a
chance to win just place a clean non offensive comment on the YouTube comments
below, and the winner will be chosen randomly by computer to get some new
lucas oil stabilizer, for their worn-out engine
so if you never want to miss another one of my new car repair videos, remember to ring
that bell!

  2. Im just here for the thick chick pic lol….thanks for the warning I’ve been using the thick stuff on my lexus for the last 3 oil changes and upon start up since using it in the morn i was hearing the hydraulic lifters tap but i always let it warm up I didn’t know i was harming the engine tanx I’ll change to the lighter stuff or should i just keep using high mileage synthetic oil alone? My is300 has 223xxx 2jz engine with vvti and is very reliable never has left me stranded and power is is at tap of the gas when I needed

  3. Appreciate your videos and tje shared knowledge, i swear by lucas but was unaware of the vvt issue using the thicker additive. Thank you

  4. Love the down to earth logic and real info with a little funny punch now and then! Great channel to watch about real stuff from a great source of experience! Thanks for helping understand what types of additives work better with your type of engine from a great name like Lucas!

  5. That thick stuff does nothing to stop rod knock or stop the new bearing from getting eaten from a slightly off crank lobe, sadly. Diff's and Manuals are about the only place this stuff is great for, the gears will be happy, though be careful, some syncro's, like in manuals that take ATF, don't like thick oil either.

  6. Bad valve stem seals and the exhaust valve seat issues are a very common cause for burning oil in a 7AFE. At least replacing the valve stem seals on these cars are very easy and you don't even have to remove the head to do it.

  7. Great historic description!! I learned a lot! Especially about that zinc additive being bad for the catalytic converter. Never knew that. Thanks very much.

  8. Question for you Scotty, hope you have time. MR2, SW20, crunchy third gear. I can change without crunching if I let the revs drop, on upward changes. Is there an additive, or a different oil that will improve this situation? All the other gears fine, just third.

  9. I had an altima that went through a lil oil but ran like a champ and never broke down, sometimes i'd throw a new oil filter own every 2000-3000 miles without draining the oil completely and it still ran fine. I would eventually drain the oil but I always added new clean oil in between changing it completely.

  10. I would love to win the oil additive very interesting stuff I watch your videos all the time I have also told my friends about your videos thank you Scotty God bless

  11. 32 of old lucas gave my 288,+ burban 5.3 25 extra psi at 1500.

    new lucas might be good for nv3500 manual trans. just a touch.

  12. I have a 1970 318 its a Plymouth fury 111 convertible , my mechanic said to use Valvoline vr1 oil , I can only find the 20w50 grade is that ok or must I run a 10w30 …the car only comes out of the garage on a nice summer day …please let me know your thoughts , thanx..its a stock engine zero modifications

  13. Scotty I have a 98 Ford ranger with a 5 speed manual transmission. It has over 200000 miles but runs great. Could I use these in it.

  14. Great content great video! Unfortunately the additives don't prolong the engine life of many domestic vehicles. Which I think many viewers are searching for. As long as the API seal is there, it wont make much of a difference if you use Mobil Purple Marvel Slick Sea Zinc Foam 50 Premium oil, from a copper funnel, or the similar additives. Take the longevity of Japan's products using simple conventional oil, at the recommended intervals, as an example. Pay attention or pay cash America!

  15. I don't have to worry about putting it into my "late-model" vehicles. I don't have any and unless I hit the lottery of some lost rich relative leaves me a bunch of cash, well, lets just say that's not in the budget anytime soon!
    Thanks for sharing!!!

  16. Is there any chance you could research and talk about the X1R additives??

    they claim they are the best and NASA uses their oil additives for 21 years now

  17. Did not know that much about additives. Good job explaining. Why is my 4 cyl saturn if sitting for couple days knock for bout 5 seconds and shoul i use a lower weight oil. Mmm

  18. So I would like to know why my owners manual for my jeep grand Cherokee. Says Oil should only be changed once a year.
    Yet I'm out buying oil and filter every 5,000 mi?

  19. Will it work for a 2003 Saturm VUE with 17,000 miles but forgot to change the oil and now the engine is knocking and shudders and barley moves down the road?

  20. Ok Scotty,
    You talked about Lucas additive in cars.
    What about using it in a 7.3 power stroke with 237,000 mi.
    I've been using it for awhile now to keep the heat down. It's been in the high 90's down here in the southern part of Ms.

  21. I say a guy pour fine saw dust in a worn out rough shifting transmission(5 speed). The shifting did smooth out and the car ran fine.

  22. I used walmart stabilizer and it oil appeared on throttle body base silver color….looked like anti seize…changed oil and it stopped appearing….there was melted tape on the air box.

  23. Guys, if you want to see something amazing, look up "Gadgetman's Snake Oil" on Google. It's a brand new oil additive that DOESN'T thicken your oil, but restores worn parts and gives COOL results!

  24. I LOVE you Scotty!! And not in a THICK kind of way….. 😂😂😂. You are a real teacher and explain the technology of cars so simply. Plus you always crack me up with your video inserts!

  25. Strongly disagree. I've tested off the shelf oils and they are ALL cheap crap. (Except the 5w-40 Euro spec formulas). Lucas engine oil treatment is nothing more than 120W gear oil (lab tested). All weights of Amsoil Signature oils hold up well but are $8/quart.
    For the best product per price and performance, Certified Laboratories Spectra Supreme oils CANNOT be beat, especialky in turbocharged engines.

  26. Dirty bad or thick wrong oil disastrous for variable valve timing phasers and sensors….
    0w20 often required…do what mfg engineers say…

  27. I could recommend a good additive…it’s called Metabond and it’s more better..I used for years on my van and my engine runs very smoothly.I definitely recommend it.

  28. There's one exception to your rule about adding additives and that is the 3 gen coyote. That engine really benefits from a proper additive like liquid Molly Ceratec. With that said, this is priceless information. 👍🏾

  29. Lol one quart of Lucas stabilizer with 5 more quarts of 5:30 mixed. let’s say on a 5.3 will benefit you from dry starts it will not cause any damage

  30. Lexus and Toyota transmissions are specifically the ones we just can't use additives in.. they will die QUICK! T-IV only!

  31. I have 1999 Jeep Cherokee that serves us as a spare vehicle. We relied on that thing for the last 15 years, and it has 300,000 miles on it. That 4.0 I6 has been good to us. The lifters are getting noisy until it reaches operating temp. It runs like a top, even today. Might try the low viscosity additive. Thanks for the info.

  32. Cool video. It's nice to hear someone tell the truth about these oil additives. Some people swear by them and some people hate them. Personally i wouldn't use it, but i also change my oil before it starts looking like pudding.
