Best Engine & Oil Fluid Additives in 2022

Are you looking for the best engine and oil fluid additives to keep your car running smoothly? If so, you’ve come to the right place. Engine and oil fluid additives can do wonders for your vehicle’s performance, but finding the right ones can be tricky. Fortunately, we’re here to help. In this post, we’ll discuss the various types of additives, how to choose the best ones, and how to use them correctly.

When it comes to engine and oil fluid additives, there are two main types: detergents and lubricants. Detergents help to remove dirt, grime, and other deposits that can accumulate in your engine and oil fluid. Lubricants add extra protection and reduce friction between moving parts. Both types of additives are important for keeping your car running smoothly and efficiently.

So, how do you choose the best engine and oil fluid additives for your vehicle? First, consider the type of engine you have. Different types of engines may require different additives. Second, look for additives that are specifically designed for the type of oil you use. This will ensure that you get the most benefits from the additives. Finally, read the reviews and ratings for the additives you’re considering. This will help you narrow down your options and make sure you’re choosing a quality product.

Once you’ve chosen the best engine and oil fluid additives for your vehicle, it’s important to use them correctly. Be sure to follow the instructions on the product label, as incorrect use can actually damage your engine. It’s also important to use the correct amount of additive. Too little won’t be effective, while too much can cause problems.

Finding the best engine and oil fluid additives for your vehicle doesn’t have to be difficult. Just remember to consider the type of engine you have, choose additives specifically designed for the type of oil you use, and read reviews and ratings. Once you’ve done that, you’ll be on your way to making sure your car is running as smoothly and efficiently as possible.

This is a fantastic item to carry in your ATV toolbox. These are used by Polaris on Rangers with built-in fuel pumps. The dealership's service personnel immediately claimed that my fuel pump was defective and wanted to replace it for a price of $1400.00. I gave them their $100.00 diagnostic cost, which I felt was a ripoff, and took it home. I normally leave working on ATVs to the professionals. Really, really, that much money for a 10-year-old Ranger? It had a completely jammed up strainer when I got the toolbox out and easily removed the pump from the tank. Easily replaceable strainer by taking tank off and snapping it into the end of the pump housing. Once again put together using the same pump and fresh gas, BOOM! It's race day, and this is the strongest I've ever run. Thank you to Amazon and YouTube. Furthermore, the service department is nothing more than a gang of robbers.

I've used Lucasoil for a long time. It helps me avoid dry starts and enhances protection for moving parts. Since I began using it, I've never experienced a significant issue with any internal engine components. I've observed indications of it performing as intended. After a recent oil change when I used 1 Qt instead of 1/2 Qt, my Evo X actually flings oil off the camshaft when I open the oil cap. I also have a minor complaint about it functioning so perfectly. The crank case breather and PCV valve tend to let more oil into my intake than they should. However, a pair of catch cans took care of the issue. Additionally, it performs a great job of reducing ticking lifters. Before my most recent oil change, my lifter was noisy. Things's excellent that the Lucasoil got in there and got it quiet. because I was going crazy from it. On Evos, ticking lifters is a common occurrence. Installing non-ticking lifters is frequently the solution. However, Lucasoil can also silence them affordably and without removing your valve cover.

Great stuff, this! You become somewhat sticky and the oil sticks to all of your vital organs. Along with five quarts of Valvoline full synthetic oil, I added a quart to my 1986 F-150 with a 302v8 engine. With only 63k original miles, I had to remove the valve cover to replace a gasket while the engine was running. After stopping the engine, I witnessed the fresh oil return to the engine and disappear, leaving no oil where it had previously been. Anyway, I restarted the engine after adding a quart of this Lucas Oil stabilizer. I just poured the entire bottle of Lucas, making it 6 quarts in my motor, rather than draining off a quart of my new synthetic oil. I've heard from mechanics that using too much oil is bad. They are probably correct, but a quart more won't do any harm. Anyway, after allowing the Lucas be installed and running for approximately 15 minutes. I turned off the engine to see if this item actually functioned as I had been told. Yes, it did. When you start your engine cold, the Lucas is already coated on all the important parts including bearings, rocker arms, lifters, and camshaft. While most of the oil flowed back into the engine, a lot of the Lucas stuck behind and left a sticky/tacky film that is extremely slick. Definitely worth the price is this item!

neutral to seals and further engine-installed materials#


2011 Subaru Impreza STI, which I purchased used for a reasonable price, has a lot of miles on it and has seen its fair share of abuse. This car's oil had clearly not been changed in a while, and it had clearly not received routine oil changes for a respectable amount of mileage. I started performing oil and filter changes every 2500 miles in an effort to purge the engine. I had gone through four of these and hadn't moved forward. After changing, oil was still getting black pretty much the next day.Following reviews, I took a big risk and tried this product. The results astonished me much in terms of how well it performed. Although synthetic oils are used in all of these contemporary automobiles, I still did not notice any muck in the drain pan. Instead, the oil poured out was as dark as the darkest night you had ever seen. The engine was noticeably cleaner after just one application, and it took a few weeks before the oil turned dark black once more. After another 2500 miles, I used it once again, and at 5000 miles, my oil is now almost brand new. One more use, and I should be good to go for a while, in my opinion. Very pleased with this purchase!In addition, my car has a turbocharger, so I was unsure if this engine flush was Turbo Safe. However, after using it for 10,000 miles, I haven't had any problems. I hope this aids in the selection of this product by someone else with a turbo automobile.

stops oil from breaking down due to high temperatures#


I bought an older vehicle with a ticking—possibly mild valve sticking—problem. In addition to replacing half a quart of oil while changing the oil, I added a tiny amount of Marvel Mystery Oil to the gas tank. One day when I was changing lanes on the motorway, another car suddenly changed lanes as well. I floored it in an effort to move out of the way. I noticed a smoke cloud behind me when I turned to look in the rearview mirror. I was referring to a massive, dark cloud as I fled. It was incredible, initially a little frightening, but then I knew my engine needed this. a great explosion. I can hear the engine of the car next to me in traffic but not my own because my motor is so quiet and idles so smoothly. On one instance, I truly believed the engine had stopped, but when I blipped the throttle, it resumed running. For as long as my car is on the road, I'll keep using this stuff.

Eliminates stiction, a common problem with HEUI Injectors, without the use of hazardous chemical strippers.#


My 2004 Ford F-250 diesel 6.0 recently popped the top of the oil filter lid during a 3/4 throttle draw. I think the final buttoning up process compromised the cap because the bulletproof kit installation overtightened it. We began looking for problems after draining all 14 quarts from the top of the motor and being driven home by a friend. We never discovered the root of the problem, but we did perform a complete oil change and utilize Motorcraft materials to replace the filter and cap. I experienced a severe bucking and "missing"-like symptom after the oil change, but it would go away as the motor warmed up to about 120 degrees. Once that temperature was reached, the motor would smooth out and resume its previous behavior. I believed that the surge I may have experienced may have harmed the injector seals or something similar. I discovered Rev-x after browsing forums and eventually arriving at Amazon's review page. I'm so glad I did because what I initially believed would be an injector replacement job turned out to merely be a stiction problem, and now all of my problems are resolved. It performed as if by magic! In the valve cover fill neck and the filter housing, I placed one bottle of Rev-x each. Powered the truck for 20 minutes. When I first started, I did still have bucking and missing, but I anticipated it as it hadn't had time to properly mix with the oil. I left the truck to sit for the remainder of the day before heading outside in the chill that evening, and she started right up! Could not be more pleased!

Absolutely compatible with all regularly used filter systems, with no deposits.

stable even when subjected to heavy persistent thermal and dynamic stresses

withstands very hot and low temperatures

able to be included with all commercial motor oils#


Due to the hard, icy winters in Illinois, my 2006 Porsche Cayenne Turbo has some minor cylinder bore scuffing or scoring. Additionally, there was a rattling, clacking sound coming from the valve lifters. The engine now sounds brand new after 200 miles of operation using the Orange Julius-colored Ceratec friction modifier. At motorway speeds, the smooth Marine V8 drone sounds like a well-oiled turbine. The surface of the cylinder bores looks to have a glass-like covering and sheen, and I recently used an endoscope to look inside one. Oil usage also lowered while mileage increased by 1.2 mpg.If the nano hexagonal Boron Nitride fuses to the cylinder walls, you won't even be able to remove it without doing some major abrasive honing work, so don't worry about the particle matter clogging oil filters.The Germans "always manufacture good stuff," as ShamWow Vince observes. This definitely IS NOT an exception!(I didn't get paid anything for this review.)

Anti-friction Liqui Moly MoS2 motor oil additive (300 ml. Can)#


I tried Slick 50 when it initially launched, but it didn't work. I'm an old guy. In the years that followed, I tried a lot of additional additions, but they weren't successful. You could say I'm a seasoned motorhead because I own a LOT of vehicles, ranging from 4-bangers to supercharged V-8s, two-cycle V-4s to one-cylinder high compression motorcycles. I've never used an additive before that performed as promised. My 2500 heavy duty pickup felt incredibly smooth and silent, and my MPGs while towing a 7,000 lb trailer jumped by half an MPG about 50 miles after being put into the crankcase. This is one outstanding supplement, and I will now be a customer for life.

Let me start by stating that I have no connection to the Best Line product in any manner, nor have I received anything for my review. This is my genuine tale.About two years ago, I paid our neighborhood lawn and equipment store over $100 to pick up my John Deere L120 garden tractor so they could give me an estimate of how much it would cost to restore it because it was running terribly. The small engine repair shop informed me that I would require a short block and that a new one would cost me about $1,000. When I finally brought my John Deere home, I thought I needed a new engine, so I kept it in my garage for two years. Up until recently, I believed I had nothing to lose and everything to gain. Then I learned about the Best Line engine treatment. I tried out the Best Line engine treatment on my John Deere tractor after watching numerous YouTube videos about it.New 5W-30 synthetic oil, fresh premium fuel, new oil, gas, and air filters, as well as spark plugs, were all installed before I used the Best Line Engine Oil additive.My John Deere L120 Garden Tractor works smoother now than it did when I first acquired it, much to my utter surprise.How is that possible? It does, though.All I can say is that I saved over $1,000 using this product, and I'll be using it in all of my cars and other engine-powered devices going forward.I would be dumb financially if I didn't.The evidence is in the pudding, and this product is authentic and not just a clever marketing ploy.Anyone who wants their engines to last a very long time should definitely consider it.Hope this is useful to all readers.I definitely ended up saving hundreds of dollars.Definitely worth the modest investment.

In 2014, I paid $150,000 for a 2005 Super-Duty PSD with 150k miles. I've spent my entire life around diesel engines on tractors, but until I acquired this truck, I had limited exposure to direct injection engines. Before getting this truck, I'd never had injector stiction. It would bog down, spit, and miss when traveling at interstate speeds. Finding out what the issue was required extensive research—the majority of forums and mechanics claimed that it required new injector(s).Then I showed up on a forum with a Rev-X fix to address the intricate stiction issue in these HEUI engines. As a mechanical engineer by training, I looked into Rev-X and discovered this Archoil as a substitute.Before the event, I never would have imagined that forcing the oil pressure to exceed 3000 psi in order to power the injectors would destroy the oil (but why didn't I?). and even after changing the oil every 5000 miles, damage was done. Every oil change is worth it for this stuff. After an oil change, I won't drive my car until I add it.The stiction was lost after a five-mile drive, and it hasn't returned. 40k miles and 4 years have passed since then. Every time I take it to the mechanic, they perform an oil health test and inquire as to whether I just had the oil changed. Ford should technically demand this for oil changes, but if they did, they wouldn't be able to sell as many injectors.Use it whenever you can, especially in motor oil.
