BMW K75 / R850 / K100 / K1100 / R1100 / R1150 / K1200 / R1200C Oil Change Kit – Castrol Full Synthetic + Hiflo Filter

OVERVIEW

This complete full‑synthetic oil change kit delivers everything necessary for routine maintenance and cleaner engine operation on classic BMW motorcycles. Designed specifically for K‑series and R‑series platforms, the package pairs Castrol Power 1 full synthetic lubricant with a high‑capacity HifloFiltro replacement filter to guarantee consistent lubrication and reliable filtration across both air‑cooled and liquid‑cooled boxer architectures. Riders looking to service their BMW touring or sport‑touring machines will find the exact oil volume and matched filter required for a precise, leak‑free interval change.

ENGINEERING & PERFORMANCE

The Castrol Power 1 formulation maintains stable viscosity under extreme riding temperatures and high‑RPM loads, delivering superior high‑speed engine protection and excellent shear stability. Combined with the HifloFiltro paper media, the system reduces internal friction and supports rapid heat dissipation in demanding BMW drivetrains. The included seal components secure the drain plug against vibration and thermal cycling, preventing leaks during initial startup and throughout the service interval. Matched to platform‑specific fluid capacities and filtered through TÜV‑approved hardware, this combination minimizes oil consumption while preserving smooth gear‑shift feedback and wet‑clutch engagement.
