Most of our customers take good care of their vehicles and always want to make sure they are using the highest quality oil and fluids. We carry the best hand picked fluids on the market, however, there is always room for improvement. When it comes to fuel and oil additive, which ones actually work? We will explain what additives do, how they work, and when they should be used.
Types of Fuel Additives
Fuel Injector Cleaners
Fuel injector cleaners are designed to eliminate the gumming properties of ethanol which is found in our fuel. A fuel injector that is clogged will not perform as it should in cold weather and deprive you of proper acceleration. Liqui Moly Jectron is a premier injector cleaner that should be used every 1,200 miles to clean out and keep injectors flowing properly.
Liqui Moly Jectron is safe for both catalytic converters and turbochargers which means that it can be used on any vehicle that uses gasoline. Proper use will reduce fuel consumption and exhaust emissions, restore performance, promote accurate injector dosing, and increase throttle response.
Liqui Moly Jectron customer testimonial: I have used this product for more than 25 years and I have tried many other prior to Jectron fuel additive and I honestly believe that there is not anything else that works as good as this product. I have one testimonial that is: amazing! I had a car that sat for more than a year with gas in the tank and I couldn’t get it to run right no matter what I did, had help from everyone. One can and we just sat and listened as it went from nearly running to a perfect purr. It’s the best.
Octane boosters help increase the octane of your fuel. Liqui Moly Octane Plus is a revolutionary product that increases the research octane number by 2 – 4 points. Knocking combustion is prevented with an increase in the octane number. The higher the octane number the lower the fuel consumption.
Many gas stations offer fuels ranging from 87 to 93, however, 93 octane fuel is not found in every state. Simply put, higher octane is better for your vehicle. Liqui Moly Octane Plus can be poured into the fuel tank prior to filling up, once you fill up the product is automatically mixed with your fuel and increases your octane.
Liqui Moly Octane Plus customer testimonial: Simply the best octane booster. I’ve tried every brand on the market and have never had the added performance benefits that Liqui Moly Octane Plus produced. I noticed it immediately after putting it in my gas tank. Since purchasing this I’ve tried multiple so-called octane boosters. And not one of them has come close to the performance gains that Liqui Moly Octane Plus gives you.
Diesel additives are a huge hit with TDI and Diesel car owners. Diesel fuels found in the U.S. are simply sub-par which means that additives should be used. Diesel additives are used to unclog diesel fuel filters and help with cold starts.
Liqui Moly Super Diesel Additive is one of our best selling products. We recommend using Super Diesel Additive every 600 miles to clean the entire injection system while protecting from contamination and corrosion. Liqui Moly Super Diesel Additive helps improve the lubrication action of diesel fuels and protects the injection pump from wear. Cetane booster reduces diesel knocking, boosts performance, and helps with cold starts.
Liqui Moly Super Diesel Additive customer testimonial: Excellent additive from Liqui Moly. I have not found an additive from this company that did not bring positive results. This product (2002 Super Diesel Additive) works great. Keeps my TDI running in top form and adds at least another 3mpg with each tank I use this additive in. Diesel mileage is indicative of the quality of fuel you purchase, so your mileage varies from tank to tank and from a distributor to distributor. But, this additive seems to correct some of the quality variances in fuel. A strong plus for every tank of diesel.
Liqui Moly Diesel Purge is another fan favorite that packs a punch. It is the strongest cleaning additive on the market. Diesel Purge will restore proper operation of the injection system by cleaning the injector nozzles. Diesel purge can be used by mixing it with your fuel or directly through the intake line.
Liqui Moly Diesel Purge customer testimonial: This stuff is one of the few fixes in a can that really works great! I’ve used it in my 2003 VW Jetta TDI with 260k miles (with original injectors and pump) about every 30k miles when the car starts running a bit rough. It results in an immediate improvement in injection pump and injector functionality, crisp throttle response and really makes it run smooth. Great stuff!
Liqui Moly Diesel Particulate Filter Protector can be used with both Liqui Moly Super Diesel Additive and Liqui Moly Diesel Purge. Short trips are bad for the diesel particle filter as they become blocked over time. Liqui Moly Diesel Particulate Filter Protector reduces the build-up of particulates which increases its lifespan while ensuring optimal fuel combustion. Reduced emissions and build up of particulates will keep your vehicle running to spec while prolonging the life of vital components.
Liqui Moly Diesel Particulate Filter Protector customer testimonial: Works just as expected. If you use this product continuously you’ll have a well-running vehicle without having to worry about costly repairs down the line. Liqui Moly delivers once again, I highly recommend checking out their oils as well… great stuff!
When should I use a fuel additive on my Volkswagen or Audi?
Consistently. Fuel additives will help keep your fuel system clean, however, they are not meant to be used once and not used again for an extended period of time. When it comes to fuels your best bet is to use the highest octane available and a fuel additive every oil change (oil changes should be performed every 5,000 miles max).
Note: Always keep your fuel level over 1/4 total tank capacity. Most fuel pumps are located in the fuel tank and are kept cool by the fuel. Fuel pumps tend to overheat which causes them to fail prematurely. Keeping a 1/4 tank will help cool the tank on long trips, especially in the summer when we have an uptick in fuel pump sales due to failure.
Types of Oil Additives
First and foremost, no oil additive will work unless you have a clean crankcase. The best way to properly “flush” your system is to do continuous oil changes. Changing your oil every 500 miles for 2,500 miles is the safest and best way to clean a crankcase from sludge and deposits, however, its time consuming and costly. That’s where a high-quality engine flush comes in.
Liqui Moly Pro-Line Engine Flush is a great way to save money and clean out your crankcase from sludge and deposits. Liqui Moly Pro-Line Engine Flush recovers oil lubricating properties by dissolving sludge which will allow oils to work properly. The best way to use Liqui Moly Pro-Line Engine Flush is to get the oil up to normal operating temperature, add the product into your oil, let the vehicle idle for 10 minutes, and perform a standard oil change. You’ll notice that the oil coming out will look a bit thinner and be very dark.
Liqui Moly Pro-Line Engine Flush customer testimonial: My A4 is over 130k miles. Ran this stuff before my last oil change, and it really quieted down my idle and smoothed it out. Great product, and well worth the price for high mileage vehicles.
One your crankcase is clean you can choose an oil additive that will increase protection to vital engine components.
Oil Enhancers / Wear Protectors
Liqui Moly Motor Protect is a state of the art product meant to extend the life of your motor while reducing fuel consumption and lowering exhaust pollutants. Liqui Moly Motor Protect will reduce friction even when used with the highest quality motor oils on the market. Motor Protect should be added to fresh oil to help reduce engine wear.
Liqui Moly Motor Protect customer testimonial: Amazing results. I have been repairing motors for over 40 years and I do not hold stock in “snake oil” miracle cures but I am a believer in this product. I put it in my 20-year-old 200,000 mile 4 cylinder engine after I replaced the head gasket. The valves were rattling like a hoard of flamenco dancers on a tin roof! (With full castanet accompaniment!) The first startup after adding the rattling subsided to the point I could not hear it at all. After 2 months it is still dead quiet even after sitting for 4-5 days in the sun. All I can assume is that this product is NOT snake oil but has been designed to do the job it claims to do. I am looking forward to another 200,000 miles on this old friend.
Liqui Moly Ceratec is a favorite among enthusiasts due to having ceramic wear protection. Ceramic compounds withstand both extremely high chemical and thermal loads prevent direct metal to metal contact. Ceratec can last up to 30,000 miles and tests have proven that it extends engine life. Liqui Moly Ceratec is one of, if not, our best selling oil additive.
Liqui Moly Ceratec customer testimonial: I drive a 2006 BMW 750i and these engines have major valve stem leak issues that cause white smoke from tailpipe. I have tried so many things and this stuff actually works!!! I don’t usually take the time to post a review but was so impressed I felt I had to in hopes to help others with the same issues I had!!!
