10020 Fuel Treatment - 5.25 Ounce

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!

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. 🚙🔧
