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

Austen: Does this work? I don't know. Only some super specific mechanic who monitors your engine over time will know if this is actually something that is great for your engine or sucks or is nothing. But it's not caused mine to fail and I "feel" like it does something. So there's that. I assume the manufacturer has done testing. But I haven't—and I still use this in my car.

Dmf: If you have a fuel-hog vehicle, adding fuel boosters like Lucas and other brand names never hurts to extend the mileage you get from every tank. I used to do it often in my Dakota, but now I have a Dodge Ram 1500, and I like getting as much mileage as possible.

Vanessa A. Gilbert: Excellent Product! I wish they included or sold separately a device/adapter to easily transfer this to the gas tank. I ordered a quart size bottle of this product also, and when it runs out I will keep the bottle and refill it using this gallon. Increases MPG, cleans fuel system, and the upper cylinder lubricant keeps piston wear and tear down to a minimum to ensure long engine life. Highly recommend!

FlyingDiver: About 20 years ago, an older guy at Pep Boys suggested we try this stuff. Our 1991 Camry, with just over 100k miles, was a little lethargic and the valves seem to pig a little bit. It’s now approaching 300k miles and still performing better than before we started using it. Now use in our 1996 F150 and seems to help as well. Great stuff. And is keeping us from being swindled by an unscrupulous mechanic. Unfortunately, there are some out there. Highly recommend.

Amazon Customer: I have owned and driven high-end mercedes AMG vehicles since 2005. I started bring this size 8 years ago. I now have an automotive business and I recommend this product to my customers. My family used it and I can not tell you all the benefits but I will tell you this: S600 167K, ML63- 140K, CL63-145K. All high mileage and the engines run like tops. Smooth, no misfiring. I buy mainly regular gas for my cars except the V12 S600. The timing is too tight.
I'm buying this company....... 100% satisfaction and great investment....

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 :)
