I have a 2006 a Toyota 4Runner 4WD V6 Sport Efition with 198,428 miles on the odometer. I have always maintained it meticulously but as I neared the 200k mark I wanted to run something a lot stronger than the usual GUMOUT fuel cleaner to see if it might remove any deposits accumulated over 20 years of driving and further smooth out the idle on this engine. The bottle is a tad hard to open, so you should open it indoors first with whatever you need to open it without spilling any of this VERY EXPENSIVE cleaner. Then re-cap the bottle and take a clean automotive funnel with you to add it to a FULL TANK of premium gasoline. (I filled up with the Super grade of Chevron Techron gasoline.) Once I filled it up I let it sit and mix with the fuel overnight so it could already start cleaning deposits in the gas tank. The next day I went on a 280 mile highway road trip and I made sure I operated the engine at a variety of speeds and gears through the day with several 30+ minute runs at 3,000 to 3,500 steady R.P.M.’s. I also did some hard accelerations to simulate passing situations to try to blow out as much gunk as possible. The engine would rev up between 5,000 to 6,000 R.P.M.’s briefly as it downshifted to accelerate. I also did some low speed driving as well during that run. By the end of the day I burned up about 15 gallons of treated gasoline and it really did the trick. When I got home I re-filled the gas tank with Shell high octane premium gasoline and over the past week I’ve been well pleased with how smooth and responsive the engine performance feels and it seems to get smoother by the day. I also did an immediate oil change which I personally performed a few days after doing the 505 CSF treatment. This allowed any dissolved gunk to be drained out with the old oil. I then re-filled the engine with Royal Purple HSX High Mileage Premium synthetic oil and a reolaced the oil filter with a high-end WIX filter that is engineered to work well with synthetic oils. This is the proper way to go about things if you want to keep your high mileage engine running smoothly. It also helps to change oil religiously every 3,000 miles or 6-months, whichever comes first. Anything longer than that is a false economy that leads to premature engine wear and eventual expensive vehicle replacement. Take good care of you engine and you won’t regret it. I’m happy with the 505 product and would use it again if I felt it was necessary, but I sort of doubt it will be. One time use at 200,000 miles is just a great way to put a little pep back into a high mileage motor and to help extend its potential life a bit longer before a rebuild is warranted. Review: Very good product and works well. ATS is a very good company with great products. - UPDATE: 06/06/2026, As promised, here is my update. This stuff works, I mean really works. I finally added this to my car at half a tank, drove fast and WOW, do I feel the difference. The car has so much more power now. It removed my rough idle and engine hesitation. It's all gone!! Seriously, this works. Amazing. I will add this in my car every year. It's well worth it. My idle in my car is rough in the mornings when I first start my car. I researched online for weeks to find a solution. I came across this product. My gas in the car is 8 years old because my car was in storage, and I cannot drain it out. This was recommended to me from YouTube, Scotty the car guy and from Royalty (Sherwood) auto care. They said they use it in many cars, and it works. It removes and cleans the carbon from the engine, injectors, fuel tank, valves, intake manifold, spark plugs, etc. I just bought it and will add it to my car soon. I know it will work especially for the price. It is very expensive. I read online that this stuff really helps with rough idle which I have in the mornings only. ATS does make the best treatments. I used them in the past. I will update my post once I use it. ## Features - A fuel system treatment that actually works! - The 505CRF formula is proven to remove tough carbon deposits on port style injectors, and direct style injectors. - Removes harmful deposits on induction ports, and induction valves. - Treats 5 to 20 gallons of gasoline or diesel fuel. - Helps restore your vehicles factory fuel economy & performance. - A perfect addition to your preventative maintanance needs! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CY8ZQ1X4 | | Best Sellers Rank | #6,155 in Automotive ( See Top 100 in Automotive ) #23 in Fuel Additives | | Brand | ATS Chemical | | Customer Reviews | 4.5 4.5 out of 5 stars (1,139) | | Date First Available | March 16, 2024 | | Item Weight | 15.8 ounces | | Item model number | DSI1030 | | Manufacturer | ATS Chemical | | Manufacturer Part Number | 1040 | | Model | 505CRF Fuel System Treatment | | Product Dimensions | 2.6 x 2.6 x 7 inches | ## Images ![ATS Chemical 505 CRF Fuel System Treatment - 16 oz Powerful Carbon & Injector Cleaner for Gasoline & Diesel Engines - Help Boost MPG, Restore Power, & Reduce Emissions - Easy Pour Bottle - Image 1](https://m.media-amazon.com/images/I/61wljcq72HL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked as advertised on my 200k V6. *by N***4 on June 10, 2026* I bought this product based on recommendations on YouTube by car mechanic Scotty Kilmer.

I was averaging 18 - 20 MPG most of the time. Of course much lower when towing a large trailer. The TPS was replaced last year and i noticed my gas milage dropped to 13 - 15 MPG for over a year. The dealer that replaced it said everything was in spec with the replacement so I didn't go any deeper with it. I saw a review on 505 CRF Fuel System Treatment and figured why not give it a try. Even though it's pricey I bought a bottle. My truck has a 36 gallon tank so I waited until it was down to 1/4 tank before adding the 505. Even using a funnel half the can ran down the side of my truck trying to get it past the POS system in the filler neck. I drove around 30 miles with the truck in 3 rd gear at 50 - 60 MPH. 3000 - 3500 RPM. At the end of the drive I was back to 18 - 19 MPG. I was really sur[rised that a fuel additive could restore lost MPG like this. Imagine if the entire bottle made it into my tank! Bottom line, this stuff works! ## Frequently Bought Together - ATS Chemical 505 CRF Fuel System Treatment, 16 fluid ounces - ATS Chemical 505 CRO Oil System Treatment (505 CRO Oil System Treatment 12 FL OZ) - ATP Automotive AT-205 Re-Seal Stops Leaks, 8 Ounce Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/616570954-ats-chemical-505-crf-fuel-system-treatment-16-oz-powerful](https://www.desertcart.sk/products/616570954-ats-chemical-505-crf-fuel-system-treatment-16-oz-powerful) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-19*
