20004 Hydraulic Lifter Additive 300 ml

I use this in two of my cars, a 2008 Chevy Avalanche and 1976 Subaru DL. It works well in both, but definitely better in the Chevy. It’s super easy to add to any engine, but I generally just add it to fresh oil during the oil change. It pretty much immediately eliminates the lifter noise that develops towards the end of the oil change interval. Plus this is from a trusted brand at a great price.

I recently picked up the Liqui Moly Hydraulic Lifter Additive, and let me tell you, this stuff is a game-changer for your engine! I was a bit skeptical at first, but after adding this magic potion to my car, the difference was like night and day. My engine runs smoother, quieter, and I can feel the power coming back. It's like giving your car a spa day! The 300 ml bottle may seem small, but trust me, a little goes a long way. I've already noticed a significant improvement in performance after just one use. For anyone dealing with noisy lifters or sluggish engine response, I highly recommend giving this Liqui Moly additive a try. Your car will thank you later!

I have seen the videos of this stuff instantly stopping lifter noises like most people looking into this product. However, it make the lifter noises less but didn’t eliminate all together. I added during an oil change on my wife’s 2012 GLK350 (128,000 miles on the car) She takes a trip once or twice a month that’s 52 miles one way. Usually when this takes place you can literally watch the gas gauge drop diving down the interstate. She was getting around 16-18 mpg and would fill up before she left and on her way back. After oil change and adding this she made her trip both ways and came back with over a quarter of a tank without stopping and filling up again. I was beyond impressed. I checked the read out on the computer when she told me and it was back to getting 21 mpg. Will definitely endorse and order again. This definitely solved a problem that I couldn’t see.

First of all, I'm not going to give this product a terrible review. This product is NOT meant for mechanically damaged lifters or parts of a valve train and is not a magic "fix your engine additive." It's meant for if you have sludge or some crud causing a lifter to stick.(which at that point you should be changing the oil on a more regular basis). My 02 Suburban with the 5.3 has a bad lifter that's ticking pretty loudly. This product did nothing for it, but again that's because the mechanical roller on the lifter is chewed up, if it was just clogged up with debris, this stuff would probably take care of that, and stop the tick. I only give 4 stars because I didn't have a chance to test it on an engine that had a lifter tick due to clogged/dirty lifters, so I don't really know how it'd work on that. For $10 I'd definitely try it again if I had another lifter ticking, because if could just be debris and gunk!

Works as its advertised. Heard the difference after 5-10min of engine running. Great stuff

Well I did read the reviews AFTER I bought it. It’s kinda like STP oil additive. It did nothing for my lifter noise.

I have a 2016 4Runner with about 206,000 mi on it. The lifter started making noise about 5,000 mi ago. I thought I would give this a try as it was talked about in a number of the forums that I visited. I put it in today and was driving tonight and no lifter noise. This stuff is like magic.

I ve used one bottle so far. This is my second order. It works on start-up lifter noise.
