If You LOVE One Of These Additives, DON'T Watch This Video!

Additives, some people swear by them. Others swear at them, so who's right? As a Certified Lubrication Specialist, I reveal the TRUTH about both Fuel and Motor Oil additives via laboratory testing and real world used oil analysis examples.
CORRECTION: The boiling point of Sea Foam is below 100C (I said Fahrenheit). The flash point is below 100F, which is what I meant to say.

[@BMoris95]

From my understanding, Seafoam is meant to be added 100-300 miles BEFORE an oil change. It is meant to help break down deposits so they are removed when changing your oil. It is not meant to be added with fresh new oil as an additive.

[@jameskoskinen6763]

Exactly. It's understandable that adding seafoam to fresh oil will have an effect on it but that's not it's intended use. The way I understand Seafoam to be used is that it's intended to act as a solvent and remove sludge deposits right before an oil change

[@RyTrapp0]

But you might as well add it just 1 car drive before an oil change - because, as LSJ showed, it evaporates at typical oil operating temp, it basically has up to the point of the oil reaching operating temp to actually do anything.

[@KStewart-th4sk]

@@RyTrapp0 Since it evaporates at such a low temperature, i can't see it being of any use at all. Didn't sound like he did either.

[@tsslaporte]

Doesn't matter it likely doesn't even last 1 mile regardless of when you use it.

[@hotrodray6802]

You missed the point. If Seafoam degrades NEW oil this much, imagine how it degrades USED oil. Grabing all that wear for 300 miles before an oil change is questionable. If you're using good oil there shouldn't be any crapp in your engine anyway. THINK ABOUT IT. ****** Berryman B12 is much much better for unsticking rings and cleaning injectors at 1/2 the price.... As if that matters.

[@WrenchHead]

"As the oil life is shortened, the deposits will increase." That's specifically why I've never felt comfortable with 10K(+) mile oil changes, even with the best oil.

[@mastercricket7626]

[@user-sf7kl9uh7k]

Use ACEA oils, they have a much better additive package.

[@typrus6377]

Oil analysis is the only way I trust past 5k. I've seen diesel engines with bypass filtration make it 15k on a change, with full-flow filter changes at 3k and bypass at 5k. I've heard of them going longer. Thing to remember there is that removing the fine contamination slows the other degradation, as well as every filter change you are replacing 1-4 quarts of engine oil, depending how big your filter is. So you get a small refresh of your additive package at that point, which helps stretch the life. But sending an oil sample out every 2-3k is good practice. It isn't terribly expensive, and can tell you a whole lot about the health of your engine. You can even see if your air filter/clean air ducting is not doing it's job right.

[@JP-xd6fm]

@@typrus6377 I have a Mercedes B class diesel from 2012 and I change the oil every time the car sends me to to so. So far so good with almost 300k km on it. And if I'm honest I have no idea how many km intervals is my car recommending.

[@bmwlane8834]

It's totally fine unless you're doing frequent shift trip or doing track days. I changed oil in my 2005 BMW 530i every 15,000 miles like the book says and I sold it to a buddy with 400,000 miles and he is still enjoying the car!

[@poellot]

I use liquimoly mos2. And I sampled new oil with the mos2 added, then used oil at change. Half of the molybdenum was in the used oil. That means half did adhere to parts in the engine as intended. I am happy with that. Startup is the only time you do not have hydro dynamic suspension and the only time you have wear. Mos2 helps reduce that.

[@DENicholsAutoBravado]

@@poellot Great question and answer!

[@19jacobob93]

The only additive I would use is the Liqui Moly MoS2 anti friction additive (the first one). It genuinely does serve a purpose despite looking like 10k old oil haha I add it to most of my older cars in particular, as well as my small engines. It always reduces oil consumption to basically zero, or at least to insignificant levels on the older engines and I also attribute it to why I get thousands of hours out of of my Chinese generators. I've seen it gradually plate and fill in the wear marks on the cam lobes of an old OM603 (Mercedes diesel) over the course of around 500km after adding. Takes some time and use for it to do its thing. I'm not sure how it goes for new engines, but it's been going in my 2019 Hyundai GDI since near new (it can prevent engines from breaking in if added too early on), which is still running as new after more than 200k, and it has been used in my M104 powered Mercedes W140 (including power steering and diff) for the past 12 years and 250k. It was originally prescribed for air cooled engines in hot climates or under extreme operating conditions, as it would prevent them from destroying themselves by preventing any metal on metal contact.

[@FormulaXFD]

I was always under the impression that Seafoam wasn't an additive, but a solvent/cleaner that you were supposed run only for a very short time just prior to an oil-change...

[@jackelracer593]

Correct

[@ctrlaltdebug]

given the boiling point and water absorbtion, sounds like Seafoam is mostly alcohol.

[@ryanrehfuss]

​@@ctrlaltdebug From what I can find, the functional ingredients are pale oil, naphtha, and isopropyl alcohol, basically a combination of lightweight solvents. It would probably be good at removing deposits if used to soak a cold engine

[@whatta7793]

You're 100% right, the bottle even says if I recall correctly "add for 100 miles before an oil change". Also in the video, he said fuel additives are good didn't he? Guess what Seafoam does.. oh, you can put it in your fuel and it cleans your fuel system?! sayy whattt?! No way! I've saved plenty of beaters with Sea Foam and MMO. Bought an OBS gunked to non belief and was struggling to hold 5 psi oil pressure. Guess what happened after putting in some good ole Sea Foam? One FILTHY oil change and 60 psi oil pressure cold startup. Same truck also had a small leak at the rear main seal. After I changed the oil that had Sea Foam in it, I put 1 quart of MMO + 4 quarts motor oil, and now, you won't believe me.. but that rear main seal hasn't leaked since then. I wonder what he would think about the OGs who would put kerosene in the crankcase every now/then and let their car idle for 2-3 hours before changing it and never having any issues with their vehicles?

[@dlg5485]

You are correct. I've been using Seafoam this way for decades. I add half a can to the oil and the other half to the gas tank about 200 miles before each oil change. Helps keep the engine and fuel system nice and clean.

Change oil again, that'll bring the oil to normal levels again. As for extra engine wear, it is already done. You can tear it down or keep driving it. If you really want to purge it do a double oil change with some driving in between. Driving to flush/ mix the oil that is in the engine.

Sludge gets caught up in the pick up tube, it can clog a hydraulic lifter there is a massive amount of things that can happen when you try to break things up in the engine rather than disassembling and cleaning properly. And no, a properly maintained engine will not have sludge buildup anywhere. Idk where you heard that is a normal thing to see with proper maintenance lol

[@Mike80528]

Ceratec is not an oil modifier. It really is an *engine* treatment in that it helps fill/seal micro scratches. That's the "cera" (Ceramic) part. Use it every 3rd or 4th oil change and you WILL experience less overall engine wear. Filling the scratches improves piston ring seal and improves bearing wear, which helps your normal oil do its job better. LiquiMoly's (the company) products generally do exactly what they say. You just have to pay attention to what the actually say they do and not what you assume they do. Same for SeaFoam.

We've removed the valve covers on engines with 100k, 200k and 300k with only surface varnish and no sludge. Just use a high quality engine oil with a great additive package.

[@fivestar2227]

There is no denying the fact that moly is a fantastic dry lube as its used for rings, bearings, piston skirts, assembly lubes, thread grease, ect. and even a trace additive in many high end motor oils. The liquimoly mso2 additive is a small particle dry lube suspended in a carrier oil that helps to evenly blend it into the oil then boil off. As long as you dont have one of those ultra low micron filters the moly will hang out in the oil until it gets mushed into the microscopic imperfections of the high friction locations resulting in less friction less wear. I use it religiously in all my motors but at 1/4 the suggested dose. Some things I notice when using it are noisy valvetrains get a near instant hush, engines last 2x-3x longer and increased power output. Also I was in a situation where a fuel injector failed while stuck open and I was able to reduce the misfire / detonation with some marv's mystery oil upper cylinder lubricant (fuel additive)

I used to use Ceratec in my vehicles, in part because it is known to quiet down the "typewriter tick" the coyote v8 makes. Just recently pulled oil pan off my cars, and the pan bottom was caked with "forbidden glitter" so I thought the bearings were shot. But, as far as I can tell, they are not. No glitter found in the VVT actuators, nothing in the valve cover...nothing anywhere else except the oil pan where it was more solid than fluid. I did some armchair research, and there are a few pictures of other people who had similar deposits in their oil pan, and you can see others showing what looks like bearing glitter in the oil. But it's not -- it's the ceretec falling out of suspension. Which really makes sense because even the bottle tells you to shake it up. Lots of good info in here. I can see now why I need to pick an oil and stick with it. Doing the OCD brand changeup throughout the year could be bad as you showed.

[@BionicRusty]

I think that was ‘Fifth Gear’. I remember it. They added different ‘performance add-ons’ to see which worked best and also used a fuel system cleaner (Redex). The fuel system cleaner, on its own, gave more BHP improvement than all of the bolt-ones together. I took a risk, about 6 years ago, and bought a Fiat for £500 (I’m in the UK) with a view of it being my sons first car if I could fix it. It ran bad and had no power. I hoped it was just the injectors and before I changed anything else, I ran 2 tanks of fuel with Redex in it. It transformed the car. I then serviced it and run it for a while, still adding Redex, until I was sure that it was reliable. My son drove and cherished it for 3 years until he traded up. It became one of the most reliable cars, this family has owned. I had to retire early due to ill health and have had to get more back into basic car mechanics as a cost saving (brakes, suspension, belts, etc as well as oil, filters, etc) and I’m loving doing what I can, which isn’t much, but more so, teaching my son. I say to him often, “just remember, every bolt you tighten relies on you staying on the road at 70mph. Before the wheel goes on, or the bonnet/hood goes down, check everything. Then double check the wheel.” 👍

Oils are manufactured with the appropriate add pack with detergents already. I don’t know why anyone would think it is a good idea diluting your oil which is engineered to perform on its own. The funny thing is it seems to be the same people who preach extended oil changes! If adding some snake oil to your crankcase (which is speeding up wear) why not just simply change the oil at a lower mileage. People will literally spend money on wearing their engine earlier (by adding these products), then they argue to change your oil every 7,000 to 10,000 miles. It makes no sense.

Per Wikipedia: The Marvel Oil Company (also known as Marvel Carburetor Company; Marvel-Schebler Carburetors since 1928) was founded by Burt Pierce in 1923.[2] Before World War I, the company produced carburetors for automobiles and aircraft. Some of these encountered problems with clogged jets, prompting Pierce to formulate a blend of chemicals and petroleum to clean and maintain them. Bottom line, this stuff works on carburetors, it's an ultrathin oil with solvents. The oil part is key in carburetors, it helps the solvent penetrate better while lubricating any moving parts. It also prevents corrosion in carburetors from ethanol fuel

[@unkhammunankh7252]

Very informative video, thanks! I had just started using Lucas Oil Stabilizer on my older 2002 Expedition which I just “restored,” hoping the additives would slow down any further wear. It barely gets driven like 30-50 miles a month, but I will stick with the engine oil only from now on!

Bought a car that I didn't know was using oil at a pace of 400mi. per quart. I used Marvel Mystery Oil in it and got it down to about 1200mi. per quart. Then change the oil back to straight oil no MMO. Turns out the car I bought had piston oil ring/oil drain hole issues from the manufacturer. The MMO seemed to be a good cleaner. That's the only claim Ill make for MMO.

[@user-sf7kl9uh7k]

Just use a ACEA oil, more detergents.

[@KenjiEspresso]

MMO I’ve used in Crankcase and Gas Tank no problems. Liquid Molly in Gas Tank on long trips think 1,000 miles gets increased fuel mileage. I use my latte mixer in my coffee 😂

[@willg.5168]

​@@user-sf7kl9uh7k ACEA oil?

[@slscamg]

I had the same results with a Toyota 2AD-FE ran the max concentration of MMO and went from 2.5qts per 5k oil change to 1.5qt. It didn’t happen overnight, in fact it took like 40k miles and 8 oil changes.

[@MrSamschulman]

After hitting 100k my volvo xc60 started using a quart of oil per 400 mi. Finally tried MMM --- one use of MMM got it down to 1 qt per 5000 mi. Blown away. But now afraid to continue!

Much needed information!! Thank you!! To make your video much easier to follow I highly recommend using your cursor as a pointer when sharing your screen graphs. The program moves so quickly it’s impossible to accurately follow along. Thanks again!!👍👍👍

I have 10 years worth of Blackstone oil analysis sheets I can firmly vouch for 3 standout additives. The first one is the regular Rislone Oil Additive in the yellow bottle, does indeed clean sticky rings and greatly reduces oil burning and afterwards wear metals were lower than ever. Second one is Liquimoly Ceretec, we ran this in over 50 ford 5.4 and 6.8 triton engines and saw a huge decrease in wear metals for 15,000 miles and 3 oil changes later (Liquimoly states it works for 20,000 miles). Wear returned to the "average" number given by lab after 20,000 miles. But we had 3 valve tritons last well over 300k and are still on the road going strong thanks to Ceretec every 20,000 miles. Third is the Liquimoly Mos, this is a great additive as well, personally ran between ceretec treatments in my personal car which was VW 2.0t, cam followers lasted 80k miles instead of the average 35k. Sold the car with original engine and turbo with over 300k on it.

Now help us understand the different standards in motorcycle engine oil and Automotive oils. Then there are the motorcycle manufacturers recommendations that vary greatly between them as some say use synthetic while others say non-synthetic with the correct letter designations for the additives. Great video on the additives! Especially as I have a DGI Turbo engine!

Love to see the results on diesel targeted additives like RevX,Archoil,Hotshots secret stiction reducer. These are very well known in the diesel industry but I can never find any scientific testing regarding what they do to your oil. Thanks for bringing your knowledge to the average consumer.

[@markthegunplumber8376]

Even Steve Morris racing engines is endorcing Rev-X and he supplys it with all his new engines. Would like to see a test on it. Also a ton of Ford 6.0 Diesel guys swear by it.

[@Will97675]

I’ve used the Hotshots stiction reducer on a 6.0 Powerstroke. It worked as advertised. Granted I’ve also heard from some users that it didn’t fix their stiction problem. I’d be interested to hear about the science behind it as I can only go by my own experience. I’d also like to see a test on Archoil.

[@bobbygetsbanned6049]

@@markthegunplumber8376 Well that's disappointing, that's about the most obvious bottle of snake oil I've ever seen.

[@tonnyletkeman2348]

Yeah, I've heard alot about Archoil and Hotshots Stiction eliminator but never seen any scientific results.

[@tonnyletkeman2348]

Also would love to see a video on Diesel fuel additives.

[@MatthewC137]

Archoil cured sticky injectors in my 2006 F250 6.0 diesel 6 years ago so I've been using it ever since. I use both their fuel additive as well as their oil additive. Lab work on my oil samples since then have always as good or better than what is typical of my engine (according to Blackstone Labs). Recent TBN at 8,500 miles was 5.9 which is quite good in my experience.

[@fuffoon]

I feel validated 😊. I have used one brand of diesel for 10 years and injectors are doing well. The proprietary detergents are are worth the price difference. Injectors are about 1000 each with labor.

[@jasonseidel9547]

I’ve owned used cars my whole life. Not lightly or gently used cars either, like resurrect from the dead or keep throwing parts at it to keep it running as long as possible used cars. And I always thought oil additives wet just what they say an additive to make your oil better or stronger or oily’er. I also used fuel additives, only when I changed the oil. Figured the new oil will capture the dirty and crap and the new filter will trap it and the new clean oil will do its job and so will the additives and whatnot. I had a ‘99 Subaru Impreza and it did have 250k miles but as soon as I started to use seafoam in the oil and other additives on top of the seafoam I started to have very weird engine issues. I get it was old and had high miles, but I could have got way more if I didn’t use those additives. Your video taught me a lot and I thank you, now use only fuel additives thanks to you.
