Lucas Oil 10512 Deep Clean Fuel System Cleaner - 16 Ounce (Pack of 2)

Incredible! Used 8 oz of the 16 oz. Bottle in my full tank of premium gasoline for my 2014 MB E-350 (17 gallon tank). Immediately I felt the difference. No hesitation, more power from start and smooth riding on the road. It also stopped some valve lifter’s knocking. Kept 1/2 a bottle for another treatment in 3000 miles. Really satisfied with this product! Lucas Oil: I would have prefer for the bottle to be transparent or have a vertical window design to be able to see how much to use.

Worked very fast could tell real quick that it helped clean my fuel system worth every penny I spent.

If you own a vehicle with "direct injection" I recommend this. It's not magic but it helps prevent the carbon buildup on the valves. Once a month depending on mileage driven. The critical and I mean critical element is Polyetheramine often shown as PEA. It is the compound that helps clean the carbon deposits off intake valves in Direct injection engines. Direct injection engines are where the injector is inside the combustion cylinder are becoming very popular now especially the ones with turbo boost, and premium fuel is recommended. Found this out the hard way on my girlfriends 2018 Subaru. Took the mechanic 3 days to clean the valves. He strongly recommended it and showed data to back up the PEA recommendation. There are other additives that also have PEA and probably work fine. I find Luca's oil to be decent and a good value in the 24-bottle case. We split it 12 each.

Works

I put in my gas tank 31 gallons, after few miles , fell my truck get speed more easy.

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.
