Description:
ATS 505CRF Fuel System Treatment is designed to be added directly to the fuel. Just remove the fuel cap and pour contents into fuel tank. One can of ATS Fuel System Treatment will treat 5 to 20 gallons of gasoline or diesel fuel. ATS Fuel System Treatment enhances gasoline to remove carbon deposits from the internal combustion engine components. This chemical mixture is proven to remove carbon from; fuel injectors, induction ports, induction valves, and combustion chambers. Carbon deposits on the injectors can cause drivability problems and poor fuel mileage. This advanced formula can clean carbonization from the port style injector and the direct style injector; increasing engine performance and fuel economy. It is recommended to use both treatments every other oil change. Do not use more than one bottle of 505CRO per oil change or one bottle of 505CRF per tank of gas. More chemical added is not better. Please follow directions! Warning: Do not mix with other chemicals in oil or fuel Not recommended for aviation engines. *Reminder: This product helps restore your vehicle to factory specifications relating to harmful carbon deposits. Know your vehicles health by seeking a trusted mechanics profesional advice.

Did it do anything? Yes. 2000 Honda V6. Had a minor throttle response lag when accelerating from idle, for instance at a stop sign. Not like an accelerator pump lag, simply a smoothness issue. After treatment the engine was quieter, smoother, and this irritation was gone. If your engine is in good mechanical condition but has many miles logged, this product just might be worthwhile. I can't recommend otherwise. Like any additive, it will not repair a mechanical problem. Think maintenance not repair. 5 stars because it did make a positive change. If a 2000 V6 Honda which is already a quiet smooth engine can be better (i.e. more like it was new) I have to deliver 5 stars. I also suggest their fuel treatment at same time period.
5.0 out of 5 stars This product actually works.
This works well! I have an '07 honda accord 2.4L LX with 190k, and it had started burning oil like most cars do. I was pissed because I've had the car 13 yrs., and religiously changed the oil with the best synthetic and never beat on it. I tried the top end cleaner routine where you remove the plugs and directly pour the cleaner into the spark plug holes,(ac-delco Top End cleaner), and it did help. The theory being your ring and cylinders aren't worn out, rather, carbon and other crud has built up in the ring valleys and around them, seizing them up, letting oil get by. I ran this at 2200 rpm for 15 min., then drained. It was a weird khaki green and brown color. Filled it with castrol high- mileage synthetic and new filter. Motor definitely quieter and smoother. Much better acceleration and power. Definitely worth the money!
5.0 out of 5 stars THIS ACTUALLY WORKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Hey, I've tried many a thing, and few were decent, but this stuff, this brand, actually works!The fuel additive was a game changer, so i tried this oil additive.Another game changer! The car runs better, it's more spirited.Tip of the hat to Scotty Kilmer for showcasing this company - Scotty says it like it is, and my car thanks him.If you have an older vehicle, this is where you give the engine a face lift - my car runs "years younger", and I've had it for nearly 10 years, and it's 25 years old! I know what I'm talking about.I'm going to repeat the oil treatment later in the summer before an oil change and really clean my car's oil system. One treatment has been very effective, and I could coast, but with a car this old, there is likely a bit more buildup in the system.
4.0 out of 5 stars Works as intended.
I bought this for a Hyundai Tucson which is known to consume oil and cause carbon buildup regularly. In October 2024 I went to Kia for their $700 engine clean out which did make it better but was still stuttering and consuming oil. I bought this in January 2025 and have drove the car 2,000 miles. The car has not hardly consumed any oil which the dealership said could happen with their product. This tells me this product has worked well cleaning the deposit buildup and the car has since ran smoothly. I can’t say it’s increased the MPGs much but it definitely worked. I also used it on my 2021 John Deere mower which was having a rough idle. It has also worked on it stopping it from revving while idling. The only problem I have with this product is the cap was broken from shipping and a couple ounces have seeped out. The company wouldn’t let me return it which was frustrating to pay so much per ounce and lose some of it. But still I highly recommend it and I will use again.

The real deal. 4 or 5 treatments of this additive just prior to each oil change will recondition internal engine to nearly new operative condition. In concert with the 505 CRF Fuel System Treatment which burns off carbon deposits from intake and ignition components - it maintains younger engines and restores older ones better than all other additives. My grandsons 17 year old RAM 1500 V-8 now runs like new thanks to these well engineered products.
5.0 out of 5 stars Fuel treatment improvement
Within 30 miles I started feeling the difference in my old ‘04 Pilot. Had more get up and go, especially from a stand still. I was hesitant a bit at the price (I usually use Lucas), but the improvements were vast! Well worth the buy!It does smell awful though. You will need a funnel to use it.
5.0 out of 5 stars Absolutely incredible, better than any alternative
Literally miracle juice. My noisy engine was burning oil, but now it sounds like it did 60,000 miles ago! Will absolutely be using this again. The idle RPMs are finally back to normal!I was looking at other cleaners to add to my oil but all of them required me to run them in the oil for ~100 miles. But with this stuff it was just 10 minutes before I changed my oil. The only annoying part was having to keep my foot on the pedal and laser focused on the RPMs for 10 minutes. But suuuuper worth it.
5.0 out of 5 stars I agree with Scotty, Great product!
Great product, but a little pricey for such a small can. Use a funnel to put this into your gas tank.

Great Result
It improves the engine life, and clean all residue of sticky oil and dirt.
