Lucas Oil Deep Clean Fuel System Cleaner, 5.25 Ounce (10669) (Pack of 2)

Works very well. 2018 Toyota Highlander became a little hesitant while merging on the freeway. One bottle easily put in the tank eliminated the hesitancy.

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

Performed as expected.

Just as advertised / Seems to make the car run extra smooth / No engine knocks / Highly recommend!

GREAT QUALITY. We have used Lucas Oil products for 25+ years. We use this product in both of our old cars once or twice a year. It works well.

Works Great

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

Just got three bottles of the Lucas Deep Clean last week and am using it in three different Toyotas. A Venza, a Corolla and a 2004 Tundra. It is working great in all 3 vehicles. I noticed the difference in the Tundra during the first 20 miles or so. The throttle response is better, the idle is smoother, and it is too soon to tell if this product is improving the gas mileage at all. This is the first time I have used the Deep Clean product from Lucas though I have used the Upper Cylinder Lubricant product fuel system treatment. The Deep Clean is much more of a 'standard' cleaner. This cleaner is high in PEA detergent which is the best substance for complete fuel system cleaning, and the Deep Clean seems to have more of it than Techron Concentrate Plus which is another great product. The Lucas Deep Clean is cheaper than the Techron too. Another thing I like is that the Deep Clean works on up to 30 gallons of gasoline, whereas the Techron concentrate only works with up to 20 gallons of gasoline. That extra 10 gallons of cleaning power meas that one bottle treats a full tank of gas in the Tundra that has a 26 gallon fuel tank. The three bottles did not leak which is good. If you compare it to Techron or to Redline SL-1 the Lucas product is quite a bit cheaper and seems more cost effective. I am not knocking the other 2 products they are all good fuel system cleaners.

قوي

Cantidad y precio correctos para lo que hay. Lo.eché en el tanque de minxohce gasolina, de unos 45 litros y cuertamente se quitó un poco es típico olor al arrancarlo un poco fuerte del tubo de escape. Cada año li usaré para un mantenimiento. Lo veo bien!

So great just as described

Good

I was somewhat sceptical about any of these snake oils for cars actually working but this does seem to improve performance and fuel economy having used it a couple of times. I'm no expert and couldn't tell you facts and figures derived from extensive research but I know how my car drives and there is an improvement albeit slight. I would probably have to keep using this on a long term regular basis to see anything better happening but I have no idea if the extra expense makes it viable. I guess it might improve the life of the engine overall so if you are planning on keeping the car for a long time it could be peace of mind for you.
