LIQUI MOLY Brake fluid

  • Pedal feel:
Rating 5.0

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

LIQUI MOLY Fuel filter

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

LIQUI MOLY Engine oil

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

LIQUI MOLY Oil additives

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

LIQUI MOLY Engine oil

  • Engine noise:
Rating 4.5

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
