Lucas Oil Deep Clean Fuel System Cleaner, 5.25 Ounce (10669)

Wonderful for my vehicle that had been sitting for almost a year without being driven. Helped to clean out the system!

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.

Convenient to order

I think redline is a better value and it’s worth it to pony up the extra $5-$6, but this a great product. Use additives with PEA once every few thousand miles(preferably before oil changes), or add a bit at every fill up, especially if you don’t use good gas

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.

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

Works great and good price

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
