Liqui Moly Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2037

Liquid Molly is the Bomb, you should use it at least 2x a year, trust me, you have no idea how much yuck I got outta my engine.

Great product, I did my 2004 audi a4 quattro 1.8t with it and it cleaned out so much oil sludge. Amazing stuff, highly recommended seller!!!

Autobahn products... As in Hard driving all the time? Best products out there!!

Good quality engine cleaner

I tried this based on reviews and feedback provided by other buyers. I used this for my 2016 CRV. I have felt change into sound of engine. Also I have see oil came out very black. It expensive but I am going to try this for upcoming oil changes for sure. Getting 4 stars because of it expensive.

Use all of this info how you please. I had a very noisy 220,000 mile Toyota and considered using this engine flush again. Decided with research just to change the oil. It completely resolved the noise it had. Sometimes, less is more. If it's not broken don't fix it. I will say, Liqui Moly is the only engine flush I will ever touch. Others are much higher risk. My experience: A Buick with 137,500 miles, many missed oil changes, lots of sludge in engine (visible under oil cap). I poured 1/3rd of this bottle in after a recent oil change. Oil filters for this car are $3-4. I changed them every 250 miles or so while driving around with this Liqui Moly engine flush (1/3rd of 355mL bottle) in my engine. Each oil filter filled up with gunk very quickly. I could hear it affecting oil flow because the valves were ticking. I changed the filters without changing the oil, because I wanted the engine flush to keep cleaning. It sounds good now. The engine runs smoothly. No sign of main bearing wear. Liqui Moly suggests using the full bottle and only allowing the engine to idle with the product circulating, for 10 minutes. I only drove around with it because I didn't know this rule. That is a testament to this product. It didn't kill my engine. Still runs strong and sounds smooth when I lean over the engine and listen to it rev. No rough noise or clatter. No signs of excessive engine wear, despite the neglect and overtreatment this Buick has been through. 3100 V6 famous for being indestructible. Not sure if that's the sole reason the engine is okay. Have read that engine flush significantly reduces your oil's ability to lubricate main bearings, pistons, rod bearings, and so on.

Car is still broke down, so I don't know

bottle came ruptured and a liquid mess spilling after opening.

Wrong item was sent and they didn't even allow me to return it in store. They shipped me hydraulic lifter fluid instead.
