Liqui moly solved lifter noise on my old Kadett.
Pros: solved lifter noise
Vehicle:
Opel Kadett
Liqui Moly Molygen 5w-40
After completing the work, I took the bike out for a 300 km ride. The improvement was immediately noticeable—the brake bite was sharper, and the spongy lever feel was completely gone.
Pros: sharper brake bite
Cons: spongy lever feel
Mileage: 300 km
Additionally, fill the big primary fuel filter (spin-on type) with Liqui Moly Diesel Puge and put the rest in the tank. This should boost the cetane rating and clean up your injectors if they’re gummed up.
Pros: boost cetane rating
Cons: clean up injectors
I recently changed the engine and transmission oil in my car and opted for Liqui Moly, as from what I researched it withstands higher temperatures compared to the OEM.
Pros: withstands higher temperatures
Lately, I’ve been diligent about using Mobile 1 synthetic instead of generic oil and have done some changes like buying top-tier fuel, 87 octane, which has detergent in it. I’ve gone so far as to do some fuel additives like Techron and have added LIQUIMOLY to an oil change.
Pros: diligent oil changes
Vehicle:
Honda
I’ve personally been running Liqui Moly LL-04 5W-30 as this grade seems a lot better to be using in a high performance engine to induce longevity. Plus the gen 2 B58s don’t have the same oil pump issues as the gen 1.
Pros: better for longevity
Vehicle:
BMW
I did an oil change with liquimolly 5w-40 and added liquimolly lifter additive, and drove it for a week hoping it would go away.
Vehicle:
Volkswagen Golf
Start by getting rid of that junk liqui moly and replace it with ROWE RS 5w40 (i can link many kits if need be)
Cons: junk liqui moly
Vehicle:
Audi A6
