Lucas Oil 10512 Deep Clean Fuel System Cleaner - 16 Ounce

This has worked, so far I’m about 1/3 of a full tank of gas through it. Idle is much better and smoother. I didn’t believe it at first, because nothing happened. But recently I notice a big difference. My engine is running perfectly, better than ever. I rated this product excellent.

Used on my 2016 corolla with 180k. Noticed the motor had a knock that would come and go so I knew the noise was an injector and not a lifter so I dumped a bottle in and problem was not only gone after a half tank of gas but the car ran better at idle.

I’ll only use Lucas in my engines. They run better, and you can notice the difference immediately. Idling is smoother as well as acceleration. Always a great product.

Convenient to order

Works great and good price

This stuff is great. Have used it several times and have seen a marked improvement in my gas mileage.

This product is great

I was told by engine builders that Lucas Deep Clean contains the necessary ingredients to clean carbon and residue from the fuel system.

É um produto bom, mas muito caro. Comprei gasolina duas vezes no posto Cidade Jardim e fez muito mal para os injetores de combustível para meus dois carros. Jamais voltarei para aquele porcaria.

Pues no me quedo claro si funcionó o no pero si note una respuesta más potente lo que duró el tanque con el botellín este

قوي

Load this up and run your car hot, good old Italian tune up. Use every 3 months or after using cheaper fuel or fueling up from sketchy gas stations.

Good
