The Best Oil Additives For Your Car (Review & Buying Guide) in 2018

This comes with 16oz, with larger packs for a bulk deal available exclusively through Amazon. Sea Foam consists of 100% petroleum, and is a PEA as well as EPA registered product for environmental friendliness.

Sea Foam works to eliminate buildup in your engine in the form of gum, varnish deposits, and contaminants found inside your internal engine. Users with older vehicles (250,000+ miles) enjoy drastic improvements, such as increased power, decreased drag, and a quieter motor. Sea Form is usable for either gasoline or direct oil injection.

Outfitted primarily for diesel engines, Archoil comes in a 16oz container, bringing a volley of benefits in a small package. Your engine noise, vibration, and friction decrease with Archoil flowing through it. This is known to fix 6.0 and 7.5L PowerStroke Cold Start Injector problems; a very simple fix for otherwise costly repair/maintenance to your diesel engine.

Archoil reduces the wear-and-tear on your vehicle while extending the life of other components, due to its lack of high zinc levels. If you were to use this in your gasoline system, you would see optimized performance in your gearboxes, power steering, and hydraulics.

300ml of additives, perfect to blend with any commercial motor oil. Whatever your preferred oil is will work perfectly, so you don’t have to compromise between the two. Liqui Moly works extremely well for long-distance travelers and those who live in extreme climates. High or low temperatures, it will perform consistently throughout.

Compatible with almost every filter system, which reduces the potential for deposits/sediment. You can utilize this product as transmission fluid, though it is not recommended to add to your fuel.

One full gallon ensures that you won’t need to make another purchase for quite some time (2 years on average, and at a lower cost than most leading oil additives). This high-performance oil additive elongates your oil’s life expectancy as much 50%, spacing out time between oil changes, which saves you time and money.

Your oil consumption rate decreases as well, optimizing your engine in every aspect. Lucas oil is made in the United States, eliminates dry starts, and gives you more power for your MPG.

If you’re a proud Ford owner, then you’ve had problems with your engine’s friction in the past. Ford’s 4oz oil additive reduces metallic surface friction while reducing hypoid gear loudness and chatter on your differentials.

This oil lubricates your injectors as well, and works exceptionally well when quieting the rear of most Ford GT and Mustang models. A tapered neck makes it easy to pour right after opening the packaging. Your car could be performing better within five minutes of receiving this in the mail.

16oz (available in 12-packs) gives you the perfect measurement to treat two oil changes with a single bottle. Slick oil is reduced on your pistons, allowing their rings to properly seat. Startup performance increases with less chatter, and a noticeable change in power (usually apparent after the second time you start the car up, once it’s had some time to run its course).

This additive contains high levels of zinc and phosphorus, making it extremely important to only use what’s recommended for your vehicle. Too much zinc can slowly degrade the smaller working parts of your motor, as we explain a bit later. Red Line decreased metal-to-metal contact, boosting your performance.

In an 11oz can, you get lowered RPM, increased acceleration and engine performance, and a better exhaust note. BG is designed to work alongside your high-performance truck engine, giving you the strength that you need to get the job done.

BG increases time between oil changes. Users reported changing oil at each 5,000 mile mark without encountering issues, while noticing a smoother transition after their second startup post oil change. Reduce sediment deposits and resist corrosion for high-performance vehicles.

Reduce stuck fuel injectors with ease, while avoiding harmful, corrosive chemical strippers. Rev X works with the most efficient additives, so you don’t end up doing more harm than good when you use their products. Turbo chargers will benefit from mild repairs due to the viscosity of the additives.

Rev X is optimal for diesel engine or gas engine use thanks to its simplistic formula. For gas, use 4oz of the 8oz bottle, for diesel, use the entire bottle. Performance improves as early as the second startup (after you’ve let it run about 15 miles).

This product reduces oil consumption, while increasing oil pressure for optimal performance. Worn seals get a revitalized boost, eliminating the possibility of future corrosion while repairing seals as well as they can be repaired.

This additive is compatible with petroleum, semi-synthetic and full synthetic oils, roughly 97% of the market’s oil base. No harmful solvents are included (which reduces odor when opening the container), which aids in a quick fix to your engine oil leaks as well.

Reducing friction and general wear-and-tear of your engine, this additive also improves your fuel performance and economy. On average, after your second oil change using BestLine, you can see a 40-50 increase in mileage on a full tank.

Harmful emissions are reduced as well. This oil additive is optimal at 10-15% oil volume (a bit higher than the standard 5% for most additives, though the performance increase is worthwhile). Engine chatter and vibration is reduced after your second startup while slightly increasing oil pressure.
