LiquiMoly Liqui Moly Valve Clean, Case of 4 IAS2001

Great

I started using this product in my 2012 3 series. When I removed the intake manifold, I found that the valves were clean, which was unexpected. Since my wife had the same direct port-injected engine in her 2016 BMW, I started using it in her car as well. After a recent service I performed on her car, I noted that the valves had some build-up. I will be using this product more regularly to clean and prevent future build-up.

Truck getting better gas mileage. Gave some to sister in-law, she says getting better gas mileage. Used in two fillups. 2 cans each. Wife says no different in her car

I have a 2.4 liter four cylinder '05 Acura TSX manual 6 speed with 120,000 miles on it. I noticed a very low volume, couldn't hardly hear it, medium high pitched noise occuring between 2000 and 2500 rpm, depending on the gear it was in at the time. I've burned through a half a tank with the added Moli; now the noise is still there but you have to strain to barley hear it. We'll see what happens when this tank empties.

I’ve used this product before. It’s as good if not better than most. Good price fast delivery.

This stuff smells good enough to wear as cologne, and also makes for instant performance enhancement during daily driving. Plus, it might be great for your valves too.

Ok, ok, so the bottle says "for port injection vehicles...". Sharing since I'm trying to clean the balance on a direct injection vehicle.

I've run 4 bottles of this, one bottle per fill up. My vehicle is a 2009 Kia optima with 212k miles. Each tank I accelerated hard when possible and floored it up some long hills on every tank. I used a borescope to check the pistons after the treatment. Most of the piston has a thick layer of carbon on it, except where the fuel injector sprays. Can't tell if it works amazing, or not at all. Car seems to run smoother and get better fuel economy though
