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.

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.

[@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....

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.

[@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.

[@ThunderHead289]

I want to play devils advocate here as someone who has ran the Lucas oil stabilizer for pretty much my entire life without issue. (Granted i drive only old-school flat tappet classic era stuff) Some positives which you almost somewhat indirectly confirmed for me here we're that it doesn't conflict with an existing additive package, only delutes it - so if you change your oil at 3k-ish like I do, probably not an issue. What I can speak to from pulling valve covers is the cling factor - it definitely keeps a nice oil film on critical parts after sitting for awhile. On a dry start after a couple days, things basically run dry till oil gets there - it's small, but compared to anything else probably pretty high wear delta. I wouldn't be surprised at all if mitigating those dry starts, especially with flat tappet cams, has enabled me to stack copious amounts of miles on old classics without any notable wear. I'm not married to either idea, but I do have reason to beleive that there is something to the cling factor. I "think" that's the sneaky sauce behind it. Would I put Lucas oil stabilizer in a modern 0w-20 type vehicle? Heck no. Wouldn't even consider it due to the viscosity. Only old-school flat tappet cam engines - and still I'm highly mindful of my oil pressure.

[@eugeneanderson7984]

I have 40 years in oil sample issues with Cat. As a Tech a Manager and a machine shop owner we will agree on use the correct oil and change it on time the best one thing anyone can do. One extended oil change will cost you more than any oil change possibly causing catastrophic failure. The # 1 issue I find is electrolosis from running nasty coolant or water. 9 out of 10 engines that must be taken out of service is generally from holes in liners. Gas engines you have an advantage on me. Mixing the additives with an aeration type mixer at room temperature may not be super accurate as oil pumps are gear driven for that reason not as much air.

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.

I’d love your input. I grew up on a large cattle ranch in the 60’s-80’s. My dad believed in Marvel mystery oil. Literally every single motor on our ranch, and many other ranches around us used the Marvel Mystery INVERSE oilers. We didn’t put it on the engine oil. Best I can remember, we connected to a vacuum line that put a single drop into the fuel as it entered the carburetors. Dad believed it kept carbon from building up. Best I can remember it added a single drop about every 20 seconds.

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.

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 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 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!

Very interesting and informative.

[@themotoroilgeek]

Glad you think so!

[@davida1hiwaaynet]

Awesome! Thank you for taking the time to make this. I have always used "just plain oil" of the same brand throughout the life of an engine. Never used additives because others have said similar things as to what you have proven here. The only product you mention which I have used is Marvel Mystery Oil, but not in the engine oil sump. It has helped me with non-destructive disassembly of rusted mechanisms, after which they are rebuilt and then oiled with what they are designed to have.

[@leifelander6230]

Have used Amsoil signature series exclusively in my vehicles , the longest I kept one was 350000 miles , still running like new . No additives needed .

[@meme8315]

Scamsoil. Your a sucker I see

[@modified15r]

I had a customer who bought a Honda new and swore by a oil that was purple in color. He used this oil from day one. When we pulled the valve cover for it's first valve adjustment at the manufactures recommended 30k miles we were both floored by how black his engine was inside. The purple dye in the oil had turned his engine black. Never heard another word about how great that oil was after that.

Royal Purple?

[@100pyatt]

​@@TassieLorenzoyou bet and he needed the royal flush after that

[@jacobhurley9587]

Lmfao that is a higher performance racing oil not meant to even be in an engine longe term. Bet that dummy thought shiiit this oil turns my car into a racecar? No sir, it turns *your* car into a brick.

So glad I found this channel. Finally , conclusions derived through controlled testing and confirmation.

I’m blown away at people’s comments, trying to refute what Lake showed in his video… just goes to show why politicians get away with lying to people & people blindly believe them!

[@aleksandarpetrovic6613]

I don't understand what he showed, why he mix it? My English not so good. But I use aditives for whole life, and I fix many problems with them, and also prevent many problems. For example, injector cleaning do very well, some cars and tools was out of oil but didn't broke, etc.

[@1HotRodHudson]

@@aleksandarpetrovic6613 30+ years ago I had a little 914 Porsche & it looked like carbs needed rebuilding. By chance I tried Techron fuel injector cleaner & I was shocked that with in 15 miles it had worked! I’ve been a believer of Techron since. So yes, some additives can help, oddly enough Lake likes Techron (complete). With oil it’s different since oil is a lubricant vs something burned in the fuel. My take on what Lake presented is this; 1) with any additive the oil is being diluted & thus the properties the oil possesses aren’t as strong as they need to be on just a concentration level. 2) some oil additives actually add harmful products to the oil others very little is added but overall it makes the mixture of the oil not ideal for the engine, ultimately doing long term damage. One may not ever see the actual damage until it breaks. Think of it like a recipe, say chocolate chip cookies with certain ingredients at specific amounts. At the correct amounts the ingredients make amazing cookies! Now let’s say we add hamburger to the cookie batter, it’s not helping the original recipe mixture at all & the once ideal cookies are now something different. Thus adding to the oil an oil additive in a bottle could (& does per Lake’s testing) cause the overall mixture to become something very different than the original oil by itself, it’s now not a good mixture which could cause damage to the engine over time. Unfortunately one would see the damage until it breaks. Hope that makes sense?

@@aleksandarpetrovic6613 He mentioned fuel additives are actually okay for cleaning, but not oil additives.

[@matt4398]

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

[@danielleroberts8964]

I add MMO to the fuel in my flathead ford, harley davidson and all my 4 stroke small engines.

[@carlpreston1680]

I think it is best used in fuels

[@nasonguy]

Only thing I add to my '43 Ford tractor's is Sta-bil in the fuel. That's it. Even the case oil is just plain old mineral oil from tractor supply. Purrs like a kitten, starts every time, the lift works great. The reason for the sta-bil is because I only go through a tank of gas every 3 months or so. If I was using the thing every day I'd just run plain old low octane and call it good.

[@MrTheHillfolk]

Aopa did an article on it back in the 80s because of the amount of people using it in planes,yet its not faa certified. It does keep those old dogs from sticking valves ,as it's a naptha based oil so it has some cleaning abilities. It's still not certified but it's still doing the job.

[@oldgringo66]

I remember when the original STP was a hot item Kendall produced a tech letter saying why would anyone add it to their oil when the major oil companies spent a gazillion dollars to remove it in the first place.

[@2nickles647]

I've seen what stp does to engines internally. 😅 I dont buy stp at all.

[@oneninerniner3427]

It's a good O ring & seal assembly lube, that all I use it for however.

[@williamtarpley4025]

STP was designed to be used in race car engines that were rebuilt after 2 or 3runs so there wouldn't be build up on all block internal parts

[@wilfredvanvalkenburgh2874]

Had an '73 Oldsmobile 350 with a bunch of miles, made the mistake of towing a trailer. Engine immediately started smoking "like a freight train". Parked it for months, thinking it's a goner. Added STP, it stopped smoking right away. Kept and drove for 2-3 more years. Your results may vary.

You won me as a sub. I highly believe in the science not the sales-promo. Thanks Mr.Geek

I love these videos! Please keep them coming! Could you please cover MOTORCYCLE oils please? Many people aren't even aware you can't pour JASO MB oil into a wet clutch motorcycle that's supposed to use JASO MA, MA2 but you CAN pour MA into a CVT scooter. I think! Would love to hear from you on motorcycle lubes. There's also fork oil, brake fluid ... very few people are covering these topics properly.

[@CL500MBZ]

Great video. I wish you could test slick50 from the 80s. 😂

[@mach1motorsports828]

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.
