Quite Impressive!
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, 10%. I should have objectively measured this using a mobile-phone app, but forgot to do so before using the product. Hence, no point doing an 'after' either. Benefit #4 - Increased Acceleration The bike feels like it pulls, maybe, 5-6% harder than before. Again, no objective measurement. Highly recommended to those who want to make their vehicles last longer than average!

A must for fuel injectors
Received as ordered. This serves my both petrol & diesel cars effectively. The consistency of the liquid is thicker & much different from the additives with almost kerosene like liquid. Lucas knows this technology well

Excelente producto
Es un producto muy bueno para evitar residuos en los inyectores mi auto lo acepto muy bien, dejo de patear a la hora de acelerar. Ya no se sienten jalones cuando pisas el acelerador.
