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
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
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
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
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

  2. What could be the very best i could do for my Bmw when i am going to change oil and filter? I had one totally succesful experience with flushing an engine real good. And later not. Now i have Bmw and i am not do satisfied with the oil consumption. I guess i have filled 12–13 litres oil on 62000km . Sometimes it seems to be marginal use considered age. And duddenly its way below low point. I have been far away from oil 2 times at very unplaned tours. And just had to drive with rattleing(from lifters with to little oil) and i want to try compensating for that to me and my Bmw. And i have some doubts about some additives. And i don’t wanna change to thicker oil either. I tried something like that thick lucas thing on a mercedes. And rod knock appeared quickly and short time later i got a totally "movie sensation" sounds when engine totalled. So till i found a new engine my car sounded like the tool box in movie Home alone coming down the stairs and through the door, and a rock crusher for 2-3km radius. So the engine was not a quitter i can say. Good or bad experiences with oil additives. It is very back and forth. But it is 2019, so it should be a lot of working stuff to expect also.

  3. take: don't use any oil additives except under some niche circumstances, because modern oil is both really good and designed by people who are WAY smarter than us, and if the oil meets the manufacturers specs it will protect your engine just fine.

  4. @scotty I have a 97’ 1.8 Toyota Corolla. What do you say about this car. I formulate 3.5 qt of really oil and use 1 qt of Lucas. Will it harm it ?

  5. how about a 2006 chevy equinox…it has 147000 miles on it and it has a light knock…should i use the additives?…i been using them on my last 2 oil changes…that thicker lucas stuff…quieted down some but should i be using the newer stuff scotty?…thx and enjoy your day

  6. I used Restore in my old 74 Dart slant six….actually worked real well quit smoking and burned a lot less oil. Drove it for 15 years…..was a free car too!

  7. I have a 2009 GMC sierra 4.8 liter. I has a stuck lifter so I put a brand new Jasper engine 4.8 in it . I have about 2,000 miles on the new engine I've changed the oil 2 times so far . I use Castrol GTX Synthetic oil , mobile oil filters I have terrible dry start any suggestions how to get rid of the dry start . Thank you.

  8. scotty knows his stuff I have seen the old style lucas make a dodge colt that wouldnt shift start working great again

  9. Thank you for the great videos. I have watched two or three dozen. I drive mostly freeway, and a little around town (Las Vegas, NV). Like you said, constant driving is ten times better than 'stop and go' driving. But I got a little carried away with specialty oils after the first 100,000 miles of using the recommended oil in my 2002 GMC Envoy. I changed it every 3000 miles. But from 100K to 150K miles I used synthetic blends, only changing it every 8,000 – 10,000 miles. And now that I'm over 215,000 miles, I'm using full synthetic oil, with a can of "Restore' and I've been going 12,000-15,000 miles between oil changes. I use the Lucas gas treatment with the better additive grades of gas, and I haven't changed my fuel filter since 50,000 miles. But in my new Dodge (I know, I know), I talked the dealer down from $43K to $19K, back in 2008, right after the economy tanked, and I only have 42,000 miles on it. I baby that truck for city deliveries and I use regular fuel, synthetic blend at the recommended viscosity and oil changes every 5,000 – 8,000 miles, depending on the weather, roads and amount of longer distance drives.

  10. Hey Scotty, I have a 2005 Chrysler T&C, had some tranny issues, I used 2 of the Lucas transmission conditioners, yes the ones you said NOT to use. My tranny is working great again and has been for over a year now. These trannies are notorious for issues, so I didn't have much to lose. Funny thing was, my pastor was the one to suggest using the Lucas in the first place. Go figure.

  11. I bought a car from the dealership and they used a thick oil additive to stop the oil leak from the rocker cover. Well little to behold it also stuffed up the lifters. The dealerships excuse is that they told me to get it serviced right away (problem was already there before I bought the car)

  12. Yup , I change my oil at 5000 to 6000 km, use the correct grade recommended by Toyota, which never mentioned any additional ‘stuff ‘ and filter with the next change.
    360k km an still going sweet..

  13. They never told anyone when they took the fines out of the oils and hot rods with solid lifter cams were blowing up all over the place when the cam lobes ended up going through the oil pump . That zinc in the oil really works well with mechanical camshafts .

  14. Cheap oil + Rislone = happy crankcase.
    Trust me. 30+ years using Rislone and Lucas products. (injector cleaner)
    They work.

  15. I added some z-max to my 2002 s10 4.3 12 years ago still runs like new I only drive it 500 miles year and change oil every 10-12 months.

  16. I have a 84 Chev Blazer 4×4. At the moment I'm using 10w40 conventional oil. You recommend any additives? I been told a few times, only conventional oil in an 80's trucks. What do u think?

  17. Another thing, I put STP in a 94 chevy S10 for a few years, with every oil change 3000 miles. Ran great for years, just sold it in 2017. No leaks.

  18. My 1995 Sea Breeze RV has a Chevy 454 in it with 92k miles. I use stp in it every oil change because the new SN PLUS grade oil doesn't have ZDDP in it. These old Chevy v8s have hydraulic lifters that spin in their bore. If you use oil without ZDDP you risk wearing down your cam lobes or destroying the lifters. You can thank Obama's EPA for removing the additive from all SM and later grade oils. 92 thousand miles in a 16,000 lb RV still doesn't use oil between oil changes. I only use Mobil 1 10w30 and stp with either a GM oil filter or a Mobil 1 filter. Change out at 3500 miles.

  19. In my 1994 GMC pick up I used Castrol GTX 10w30 and 2500 miles oil changes. At 140k miles when I bought it it used 1 qt every 1000 miles. After 6 oil changes it went to 1 at in 3500 miles. Switched to Mobil 1 full synthetic and oil use stopped. Drove that truck another 100k miles sold it at 240k miles still not leaking or using oil in 3500 mile oil changes.

  20. I have a 1999 Toyota Corolla, I use Castrol gtx 10-30 synthetic oil, vehicle has over a 150 thousand miles on it, car still runs in great shape, also no oil leaks.💯

  21. Reminds me of those old time used car lots..owned by "Honest Sal"..sawdust in the differential, heavy gear oil in the engine, cork dust in the radiator-anything to make an old junker look drivable.

  22. Scotty gets paid by lucas oil! It is better to just put synthetic 5w40 instead of 5w30 in it, it is also slightly thicker but doesn't cost as much as lucas oil.

  23. I had a 1955 Chevrolet Bel Air with a 350 used a quart of oil every tank of gas and I put Lucas Oil Stop Leak in it and it didn't use any oil, if it did it was very little… it was the main bearing that was leaking and Lucas stop leak stopped it from leaving!

  24. I have used that Lucas transmission fix in an old 2000 Kia Sportage w/auto trans. Put it in 7, or 8 years ago when you could tell something wasn`t quite right with how the trans was acting. Still driving it today in 2019.

  25. So question I have a 04 chevy 4.3 and I used Lucas and rotary to B&G . Now it is hi miles so do you recommend not using it? Never had a problem

  26. I had an Opal1900 and the worst thing I ever did was put Quaker State oil in it…..had to have lifters replace twice….then mechanic told me that Quaker State was ok for big engines, recommended Phillips 66 Trop Artic and never had another issue with engine.
    He told me NEVER flush engine, to only put a little automatic transmission fluid in crankcase a few miles before oil change. The engine was clean when I pulled rover arm cover off.
    Great advise from a mechanic who knew a lot about the additives and what they really do.

  27. 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
