Klotz 20W-40 Synthetic Oil Change Kit for Indian Thunderstroke — 6 Quart with HF-175 Filter, JASO MA2

Klotz 6 Quart 20W-40 Synthetic Oil Change Kit (KH-123) is a complete service set engineered for Indian Thunderstroke V‑Twin engines, supplying multi-viscosity synthetic oil, a premium oil filter, and copper crush washers in one box.

This kit bundles Klotz synthetic 20W-40 multi-viscosity engine oil with a Hiflofiltro HF-175 filter and two Cometic copper washers to simplify routine maintenance on Indian Thunderstroke motorcycles. Formulated for the thermal and friction demands of large V‑twin engines, the oil aims to maintain clean internals, reduce wear, and support stable transmission performance where JASO MA2 compatibility is required.

How does this kit protect a Thunderstroke engine under heavy use?

The Klotz 20W-40 synthetic blend uses high-grade base oils and advanced additives that help preserve piston ring seals and resist oxidation at elevated temperatures. Friction modifiers and polymers are included to manage operating temperature and reduce internal wear without compromising gear clutch performance.

• High-quality base oils for thermal stability and oxidation resistance
• Friction-modifying chemistry to lower operating temperature
• Detergents and dispersants to limit deposit formation
• Formulated to maintain clutch and transmission compatibility (JASO MA2)

What exactly is included and why each part matters?

The KH-123 kit contains six quarts of 20W-40 multi-viscosity synthetic Klotz oil, a Hiflofiltro HF-175 oil filter, and two Cometic copper crush washers. The oil provides the lubrication and additive package; the filter traps contaminants; the copper washers ensure a reliable sealing surface at the drain plug.

• 6 quarts Klotz 20W-40 synthetic oil — correct capacity for many Thunderstroke services
• Hiflofiltro HF-175 — OEM-equivalent filtration performance
• Two Cometic copper washers — replace crush washers each drain for a leak-free seal
• Packaged as a single kit to simplify parts sourcing and service time

Which Indian models and years is this kit compatible with?

This kit is selected to suit a broad range of Indian Thunderstroke V‑Twin motorcycles across recent model years. It covers multiple Chief, Chieftain, Springfield, Roadmaster, and other Thunderstroke-equipped variants — check your owner's manual for official oil spec confirmation.

How does Klotz differ from budget oils for motorcycle service?

Klotz prioritizes advanced additive packages and quality base stocks rather than cost-driven substitutions. That approach focuses on maintaining detergency, corrosion protection, and long-term ring seal integrity in heavy-duty V‑twin applications.

• No ingredient downgrades; engineered additive chemistry to protect both engine and transmission
• Formulated for deposit control and extended high-heat stability
• Designed to balance lubricity with clutch and gear performance

If you maintain Chief, Chieftain, Springfield, or Roadmaster models and prefer an oil engineered for V‑Twin thermal loads and clutch compatibility, this kit provides the oils, filter, and washers needed to complete a standard oil change with minimal parts hunting. Always confirm your motorcycle’s manual for capacity and spec details before starting service.
