Lucas Oil 10020 Fuel Treatment-155ml

I used Lucas Oil 10020 Fuel Treatment to help diagnose and fix a misfire issue on my Range Rover, and I’m genuinely impressed with the results. After adding it to a full tank, the engine began running noticeably smoother within a short period of driving. The intermittent misfire I’d been experiencing was significantly reduced and then completely gone. It clearly did a great job cleaning the fuel injectors and fuel system, as throttle response improved and idle became much more consistent. The engine feels smoother overall, especially under load, and acceleration is noticeably better than before. The 155ml bottle is very easy to use and the dosage is straightforward. It’s reassuring to use a well-known, reputable product that actually delivers real-world results rather than just promises. While it won’t replace mechanical repairs where there’s a serious fault, this was an excellent and cost-effective solution for what appeared to be a fuel-related misfire. I’ll now be using it as part of regular maintenance. Highly recommended, especially for anyone experiencing rough running or misfire issues. 🚙🔧

Would not use anything else.

Have no idea if this product actually works but will keep using it-based on all the reviews from professional mechanics. My car is running well so maybe it helps. Simply pour into tank when its almost empty and fill the car to the top.

I was having a miss on my Nissan Xtrail and was told to try this product and it's worked, miss is gone.

A had cylinder one p0263 code. Before I got the code, I had dropped from an average 46mpg to 42 mpg and didn't know why until the engine light came on. I cleared the light and added Lucas to half a tank of fuel, and by my next fill up I was above an average of 46mpg. Amazing stuff.

Good

Car used on: Ford Fiesta 1.6 Zetec S Tdci Prior to using this I had used other fuel system cleaners and they did work but improvements weren't great. Upon using this i felt very let down. My initial thoughts were "what a waste of money" literally no difference! Then..... Much to my amazement, about 50 odd miles into my journey i heard a real dirty noise. Almost like a misfire. Lasted about 2 seconds and then bang: a small cloud of black smoke and my car felt smoother immediately. I was a little concerned so i pulled over and then realised it may have been the product i had used. So i reset my MPG calculator (which read 54mpg) i also have a custom aftermarket display that shows gallons in squares and colours. Immediately i started driving after turning car off and on again and the MPG calculator kept climbing until it reached 69 mpg :o After another 50 odd miles the fuel gauge had hardly moved, and about another 14 odd miles later the squares that displays the gallons was minus one. Eventually the mpg calculator averaged 66 mpg. According to my calculations and the system, my average was 63 mpg. Thats an increase of almost 9mpg. I'm not promising you'll get that but thats been the case now two weeks on. After about 300 miles i still had half a tank and my car ran A LOT quieter. My tank is 40 litres and costs £52 to fill with premium diesel. This product is amazing. For me at least. Price is about £1 more expensive here on Amazon (sorry amazon) but the fast delivery was well worth it. 5 stars all the way. Will be using this every 2 months to maintain the clean fuel system

Brilliant product improvement on running and starting very pleased how quickly it works.

Actually, improved fuel consumption

No noticeable change in the performance of my i20 diesel.

I came across this product on YouTube from Auto edits. I liked what I had seen, so I bought this bottle to try. Well then I bought 3 1l bottles, then found the 4l bottle. I was very surprised. The engine revs from park stay the same when at idle then sliding into drive. It has more perk and even got more km in my last hwy drive. I'm very happy with product and highly recommend it.

The Product arrived a week earlier than mentioned by Amazon although it should have taken about two weeks with shipping i believe. So the "Lucas UPPER CYLINDER and Injector Cleaner" does exactly what it says in the description on the bottle. I have used this product so far in two different BMW engines: the M52B28 and the M62B46! Both engines are equipped With passive injection systems that deliver the Fuel into the intake-manifold right before the intake-valves. Both engines started to run a little smoother and quieter after about 35 to 50 km of regular driving. The engine response was a Lot quicker and in Terms of fuel economy in both Cars ist saved ne about 0,5 liters on 100Kilometers. Next time before i even think about replacing Injectors or Something Else in the fuel line (exept any sort of Filters of course) i'll try a bottle of Lucas and see what that helps. All in all i am very Happy that i found this product and that i can get it here on Amazon from time to time! Thank you for taking the time to read this reply, I Hope it helps!

Excelente, nota-se mesmo no rendimento do motor (carro gasóleo 2007)
