Frequently Asked Questions

What does Rislone Fuel Injector Cleaner do?
With continued use, it reduces carbon build-up which causes pre-ignition, power loss, burned valves and broken rings. It also cleans injectors to reduce loss of fuel economy, hesitation, pinging (spark knock), and helps restore performance.

How does Rislone Fuel Injector Cleaner work?
This product contains a unique blend of additives that clean & lubricate the entire fuel system, including fuel tanks, lines injectors, and even carburetors on older vehicles.

How can this reduce a noisy fuel system?
The UCL (Upper Cylinder Lubricant) additive lubricates the fuel pump, injectors and upper cylinder to reduce friction & wear, reducing noise.

How much will my fuel economy improve?
This varies depending on the age of the vehicle, the quality of the fuel used, and how dirty the system is. It is normal for larger increases in KPL on the first dosage and then it will usually taper off and flatten out from the second dosage on. For best results use with every tank of fuel.

Will this work with Diesel Fuel?
Yes, Rislone Fuel Injector Cleaner is designed to work with all diesel engines including ULSD Ultra Low Sulfur Diesel and Bio Diesel Fuel.

Will this harm the oxygen sensors or plug the catalytic converter?
No, this will not harm your engine or any emissions components including catalytic converters, oxygen sensors, or the EGR valve.

How much do I use?
Pour entire bottle into fuel tank. One bottle is concentrated to treat up to 75 L of petrol or diesel fuel. For smaller engines use ¼ bottle for every 19 liters. Larger vehicles use 50 mL per 20 liters of fuel. NOTE: For vehicles with known fuel lubrication problems, double the dosage.

Can I use in E-85 ethanol in my flex-fuel vehicle?
Yes, Rislone Fuel Injector Cleaner with Conditioner & Treatment works with the E-85 and will lubricate the fuel system reducing the negative effects that ethanol has on the system.

Will this bottle work in capless and obstructed fuel systems?
Yes, this bottle has special neck threads which allow this product to be safely and easily poured into all fuel tanks, including capless (no fuel cap) systems.

Can I use in my turbo charged or direct injected engine?
Yes, this is safe to use and works in all domestic and import turbo charged and directed injected gasoline (GDI) and diesel engines like the Ford EcoBoost (gas) PowerStroke (diesel) and GM Ecotec (gas) Duramax (diesel), Dodge Cummins Ram (diesel) and all others.

What is a capless fuel system?
Capless fuel systems go under a few names like Ford’s Easy Fuel System, but basically it is a vehicle with no regular gas cap. Capless systems are on many vehicles including Ford, Chrysler, Dodge, GM, Cadillac and more. The reason the car companies are moving to this system is to prevent fuel evaporation and emissions issues if the gas cap is left loose, not installed or is lost. Rislone is one of the fuel additives that will easily work with all capless, obstructed and regular fuel systems in cars and light trucks.

Can this replace the lubricant in the ULSD Ultra Low Sulfur Diesel Fuel?
Yes, Rislone Fuel Injector Cleaner with UCL is an excellent lubricant and will replace the lost additives in the new reformulated diesel fuel.

Does it work with both fuel injected and carbureted engines?
Yes, this multi-vehicle formula works with all fuel injected, port fuel injection (PFI), direct injected (DI/DIG), gasoline turbo direct injected (GTDI), turbocharged and carbureted engines.

    Don't waste your money - these people will not help you
    On March 9th 2024, I purchased a MCombo Lift Chair costing $785. On the same day, through the same Amazon account (my PERSONAL account since I also have a business account), I purchased an Asurion Complete Protect policy at the cost of $16.99 per month plus taxes. About one month ago, a problem arose with the chair that required me to make a claim using the "Complete Protect" policy that I had purchased for that very item. The claim was initiated on January 1st, 2025 - On January 3rd, I received an email asking me for photographs showing the damage for which I was making a claim. I sent those photographs via email to the address provided on January 6th. On January 27th, having not received ANY response from Asurion, I contacted them via phone and was told that my purchase had been made with a business account, that it was being used for business purposes, and was therefore not covered. I assured the Asurion Representative that it was most certainly not a business use, and that the chair that I was claiming for had been purchased because I had extensive shoulder surgery done that made it impossible to get in and out of bed. After speaking (unsuccessfully) with the Asurion Rep, I then contacted Amazon Customer Service. I spoke with an Amazon Customer Service Representative on the phone who confirmed that I had in fact used my personal account to purchase the chair and the Asurion Complete Protect policy. That representative went on to send a message to Asurion on my behalf confirming that the purchase was for personal use and not business use. Asurion responded, asking me to call them with the order number for the Asurion purchase. The number I gave was the exact same order number on my order history, however, the Asurion Rep could not find it. I was finally able to discover that the order number in Asurion's system was entirely different and isn't even in the same format as an Amazon order number. Upon the Asurion representative finding my plan, she informed me that the chair was listed as being purchased for business use (despite Amazon confirming that it was NOT) but that I should give them "a couple of business days" to resolve the issue. Five business days later, still no response and so I called them again (Yesterday - February 1st 2025)... Lo and behold, I got the same crap yet again... the purchase was listed as business use and was therefore being denied, but she promised to remove the business use commentary and put the claim through again. Today, February 2nd, I called Amazon yet again to escalate and had to call THREE times because the first two calls resulted in me finally being connected to an Asurion representative (two different reps) and each time, the Asurion representative hung up the phone as soon as my name was mentioned. It has become clear to me that the Asurion "Complete Protect" policy is a SCAM - they will NOT take care of your issue, regardless of how long you've been paying. I have been paying every month since March 9th last year - so they've received over $170 from me thus far, with zero other claims, and if I am able to cancel right now, I will only receive $16.99 back. All I want, is the chair that I purchased the policy for coverage of, to be repaired or replaced. Asurion are NOT helping, and are actively avoiding contact. At this point, I am considering legal action against Asurion for fraud - perhaps even a Class Action. I'll wait and see if my issue gets resolved within the next 10 days or so.

    Asurion is AWESOME!
    Ok, so let me start with the fact that you should NOT waste your time calling Amazon's customer service if you think you have a claim under Asurion's monthly protection plan. CALL ASURION! I wasted almost an hour with Amazon representatives that have absolutely no training in how the Asurion plan works, or even any idea if my item was covered. In fact, they told me the mechanized chair I purchased under the plan wasn't covered! Finally, my call got escalated to a manager who was just as clueless about my coverage, but had the best idea ever... call Asurion! The smartest thing I did that morning was hang up with Amazon, and reach out to Asurion as I should have done in the first place. Dealing with Asurion's customer service, after my Amazon call, was like being elevated to VIP status! 😄 Asurion's rep nicely took all my info, including the chair's purchase date and order number. Then they asked that I upload a couple of pictures of the product, along with a written description of the malfunction I had mentioned over the phone. This is where it gets really good. They told me they'd review the claim to determine if they'd send a repair specialist or reimburse me the cost of the item. In less than 48 hours, they determined that a payout was in order, and sent me an email that included an Amazon gift card for the total cost of the item minus the taxes I had paid, which I loaded directly into my Amazon wallet. Apparently, Asurion does not include the purchase taxes in their coverage. But, I can live with that. All in all, Asurion's claims division get a double thumbs up 👍🏽👍🏽, and the company gets big ups from me for not only standing behind their protection plan, but doing so expeditiously! Special note: If you buy a lot of stuff from Amazon, and have Asurion's monthly protection plan, scroll the item listing before pulling the trigger on your purchase... you need to see the green streamer that indicates your product is protected by the plan. If you don't see that, check to see if there are alternative products that might be covered. There are very few electronic or high ticket items that aren't covered, but looking for that green banner in the item description that says it's covered is key to foregoing any future headaches.

    If they can't fix it they will replace it.
    This protection plan that i pay monthly for paid for itself ten fold. My 3D printer just quit working and after the manufacturer warrenty had ran out at that. I submitted my claim they emailed me a shipping label in which I shipped out my printer that same day. Two days later they received my printer determined it couldc not be fixed and sent me a Amazon gift card for the full price of my printer. Today I will be receiving my new 3d printer thanks to Complete Protect. I highly recommend anyone and everyone to purchase this policy. This warrenty is like having a home warrenty like Homeshield but for your electronics and probably other stuff that i just have not read to see what else. This insurance will save me so much money over the corse of this year and every year after that. Thank you Complete Protect.

    "Outstanding support and a seamless process!"
    Great experience with Asurion insurance through Amazon. I wasn't sure how to register my items for the monthly plan, but the customer support team in the chat was incredibly efficient and guided me through the entire paperwork process smoothly. Furthermore, the service I received at the repair shop (Break Fix) was excellent. The whole process was seamless, and I received my digital gift card without any issues, which I’ve already applied to my Amazon account. I am very grateful for their professionalism and how easy they made everything. Highly recommended!"

    Received giftcard money to replace my plan-protected malfunctioning motherboard
    I've been subscribing to the Asurion protection plan for a while. Recently, an Asus Prime PC motherboard I had bought a few months ago on Amazon stopped working well. I ended up considering filing a claim with Asurion to see if they would either fix/replace it or issue the purchase price money, so I could buy the failed electronics replacement component again for my custom-built PC. I went to the protection plan's website and started the claim filing process but couldn't find the category my failed component would be under in order to select it from the drop-down list. I ended up messaging the live customer service. The chat messaging was somewhat slow, the agent told me they were experiencing some communication delays throughout their systems. Ultimately, the agent was very kind and understanding, and completed the claim filing process for me on her side by asking me to provide the necessary info such as the item's product name, date of purchase, price before taxes, etc. I received a printable UPS shipping label in the email, printed it, and returned the item in the mail. Approximately 2 days later, I received an Amazon giftcard code in the email with the dollar amount equal to the item's price before the sales tax. Then I redeemed the giftcard code on the Amazon page and proceeded to apply the giftcard money to my next purchase of a replacement Asus prime motherboard, and it all worked out successfully. Therefore, I had no issues with the protection plan service and recommend it to others.
