Liqui moly solved lifter noise on my old 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.
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.
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.
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.
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.
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.
Start by getting rid of that junk liqui moly and replace it with ROWE RS 5w40 (i can link many kits if need be)
