About the Liqui Moly products I highly recommend them. I’ve used their flush twice and applied Cera Tec once. I use their Leichtlauf 5w-40 oil with MANN oil filter and my engine is very smooth. Great products!
Reviews of LIQUI MOLY engine flush
My 2014 GLI (2.0T engine) was consuming oil at one time, almost a full quart in between oil changes, and there were not any visible oil leaks underneath the car. I switched to doing my own oil changes using a cheap oil extractor I bought on amazon, Liqui Moly 2332 full synthetic, and using Liqui Moly engine flush right before oil changes, and it has made a big difference, with no oil breakdown or oil consumption in between oil changes.
I've ordered some engine flush along with more Liqui-Moly oil.
Before you tear it down, run an engine flush per the can instructions...Try the LiquiMoly engine flush, drain the oil/filter change, replace the oil.
The combination of the LM flush, Seafoam Spray cleaning and Restore additive has completely stopped the lifter noise.
I used their engine flush on my last oil change. I can't say I really noticed a difference as far as a smoother engine, but I figured at 157,000 miles and an unknown history it couldn't hurt to run it.
