Ted: Use this in my diesel dually. Increases fuel milage and gives me quicker response when driving and pulling heavy loads. Keeps injectors clean as well as the whole fuel system.

Perfect Size and fitment: Don't know what happened or even if these Lucas Fuel injection cleaners come without a cap but they should. Don't like the idea the bottle could be a return and could be putting something in my gas thank that could break and ruine my Vehicle. Still added it so fingers crossed 🤞🏾
But package 📦 was packed well and arrived on time.

S. B. Wa. State..: Better gas mileage. Better idle and acceleration response. Just add few oz. To each full tank of gas. You should see and feel the difference within 100-250 miles. ( It'll clean carbon build up in valves and lube injectors.. two . 👍👍

adobe subscriber: This stuff has my 2008 RAV4 running a whole lot better. Before the valves were ratting even after using high grade fuel. Hard starting also. This vehicle also had a recall on it for excessive oil consumption and it really used the oil About half a quart every 500 miles or so. After using this stuff about 5 oz. in the tank every time fueled I see a lot of improvements but not better gas mileage. Starts real well now, whole lot less oil consumption, and little to no valve chatter or rattling. Also I went to a lower grade fuel which saves money, about one dollar per gallon. The vehicle seems to use more gas now as I think everything was cleaned by this stuff, but it runs for now 100 percent better. Maybe the valves and fuel injectors were very dirty causing most the problems.

Veaceslav: Even though my car has already traveled 200,000 miles thanks to this magical additive, it has almost no equal on the highway. The engine was cleaned of dirt and looked younger. But a month ago I came home with almost nothing on the cylinder, and the craftsmen calculated more money for repairs than the price of the car itself. Only 180 grams per full fill and you have no problems or stress with the engine and fuel system. I recommend it from the bottom of my heart

Troy Stout: I’m a mechanic. Used vehicles injectors need cleaning. Older cars injectors get gummed up over time. I bought a 2011 4 cylinder Chevy Malibu as a flip car. It got… abysmal gas mileage. And it ran like garbage. I bought this to clean out the injectors on the car. Well to my surprise, the car actually got better gas mileage AND did run better. So I ran it in my personal 14 Toyota Corolla and 13 Ford F150 (5.0). Both vehicles are about 10 years old, it was time to put some love into them. The car gets consistently 4 MPG better now. The truck achieves about 1 MPG better, which I will take. The proof is in the pudding- this actually does clean out injectors (as I expected it to) and it also gets you a noticeable increase in MPG. If you do the math- buy the cheap gas and add this to it. It’s literally cheaper to just run this along with cheap gas, versus paying for top tier gas. Hope this helps.

Anurag Chatterjee: The purpose of using this product for me was SOLELY to preserve and increase engine life. However, I was pleasantly surprised with the results!

Research shows that the highest amount of wear in a petrol engine occurs at the uppermost parts of the cylinder and piston, during cold starts.

The product was used on my 2014 Royal Enfield Continental GT 535, in Kolkata, starting in the last week of Feb, '23. The bike now has just under 29000 Kms on the odometer.

I mix 2 ml of Lucas/litre of regular petrol (using a syringe)

Benefit #1 - Fuel Economy Increase (city-riding only, no highway)

AFTER using Lucas - 29.13 Kms/l (403.7 Kms for 13.86 litres of petrol - just over one, full tank)
Before using Lucas - 27.34 Kms/l (388.2 Kms for 14.2 litres of petrol - just over one, full tank)

Benefit #2 - Emissions' Decrease (Bike ridden for about 20 mins before each test)

AFTER using Lucas: CO - 0.18; HC - 11 (lowest values EVER, test date - 24.05.2023)
Before using Lucas: CO - 0.56; HC - 28 (test date - 25.11.2022)

Benefit #3 - Reduced Vibrations and Engine-Sound Volume

Engine sounds a little quieter. Vibes have reduced by, maybe,...

Honest Reviews: Ich pack 100ml jede 2 Tankfüllung rein und merk deutlich und spürbar einfach nichts.
Aber liegt vielleicht auch am Auto bzw am Motor der bei mir von haus aus schon sehr angenehm läuft.
Dazu bezweifel ich dass es leistung bringt.
Aber mein gewissen ist beruhigt :)
