## 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.

Review: Worth every penny - Great product. My big Lincoln went from a normal 22mpg to 25mpg just from having 505 CRF clean the fuel injectors in one tank of driving. Highly recommend. No, it isn't cheap, but you'll more than make the cost back in better performance and better mpg.
Review: Works as intended. - How I used the product: I poured entire contents of bottle into a 2012 Toyota Camry Hybrid XLE. The car had roughly 12-13 gallons of gas when I used it. I drove mostly normally, but used engine braking to increase rpm downhill or whenever possible. It took roughly 1.5 weeks for the fuel containing 505 CRF to be used. Why I purchased the product: I mainly purchased the product as a way to fix what I felt like was throttle lag. The acceleration felt weak. Fuel economy was also a consideration on the value of this product to me. My concerns: I was skeptical of this product working due to my car being hybrid. Within the past 2 years I have also changed my Hybrid battery and noticed better fuel economy with that, but performance was still lacking in my opinion. What I experienced with CRF 505: At first, I didn't notice any changes. Not for several days driving. The car still felt "squishy" as it had been. Then somewhere between 1/2 and 1/4 it starting feeling much more responsive. The acceleration is smooth, fast, and stronger than ever. The car went from being a bit of a chore to drive to becoming fun. It feels much safer to have the car be responsive to my controls. Gas economy(full transparency): I am sure many people that get product's first concern is if this will generate enough value from the save fuel economy. I don't have enough data currently to be conclusive due to several factors such as: I haven't had fuel filter cleaned, I haven't driven a full tank of since using the product, I rely on the mpg avg display which can be off several percentage(even -/+ 5% is the difference between ~4mpg in a Camry), and driving style(due to difference in acceleration driving is slightly more "aggressive". My opinion(Should you use it): I am more than happy with my purchase. The product did what I wanted it to do. The performance improvement alone is enough Value for the Money for me, and any fuel economy is just a bonus. I believe that if I had used it on 5-7 gallons of gas it would have probably helped the fuel economy more than me using it on >12 gallons. The only reason I would have to not buy the product again: It worked correctly the first time! Follow up plan: My follow up plan is to follow this up with occasional fuel treatment using Marvel's Mystery oil, and to pay attention to my mpg to see if any changes.

### ⭐⭐⭐⭐⭐ First-hand evidence proves product very effectively cleans carbon build-up internal of your engine
*by B***. on February 4, 2025*

I have a 2016 Jeep Cherokee with 330,000 miles. After amazing results using ATF Chemical 505 CRF Fuel System Treatment (see separate review), I ordered this ATF Chemical 505 CRO Oil System Treatment. I believe my results are of particular interest because I did not perform the treatment by adding the product to dirty old oil, as you would right before an oil change, but I added the product to fresh clean oil right after an oil and filter change. Wait till you see what happened. The instructions say to add the product to your engine's oil, run the engine at "high idle" (some mechanics say @ 2,000 RPM) for 10 minutes or more, then drain the treated oil, remove the oil filter and install a new filter and new oil. However, what I did was last night I added the product to the fresh oil that was in my car, ran the engine at regular idle speed (say 750 RPM) for 10 minutes, turned off the engine and let it sit overnight. This morning I started the engine and moderately drove the car (2,000 RPM max) for 40 minutes, parked the car and let it sit for a few hours, then drained the oil. I was very curious to see what the oil looked like when I drained it. Would it look like the brand new oil that I had just put in the car? The answer is an emphatic NO - the oil was PITCH BLACK - it looked like old oil coming from an engine that was overdue for an oil change. In my opinion this stuff does what it was designed to do. It cleaned out the built-up carbon deposits internal of my engine. After installing a new filter and new oil I drove the car today as normal for about 90 minutes around town and highway. It is probably too soon to tell but I think the engine runs smoother and quieter. I will now be using these products on all my vehicles (5 cars/trucks, 4 motorcycles) and recommending this product to everyone. I am SO glad I found out about these products from a mechanic on YouTube who says these are "products your mechanic does not want you to know about" and that they will "make your vehicle last 3x longer". I have no doubt this is so. Easy to use. Does as advertised. Worth every penny.
