Indian Motorcycle Thunderstroke Oil Change Kit — Semi‑Synthetic 20W-40, 6-Quart with OEM Filter & Washers

Complete oil change kit with semi-synthetic 20W-40 motor oil, oil filter and drain washers engineered for Thunderstroke 111/116 air-cooled V-twin engines.

This Indian Motorcycle Thunderstroke Oil Change Kit (Part 2889311) bundles the oils and hardware needed to service Thunderstroke 111 and 116 cubic inch air‑cooled engines. The semi‑synthetic 20W‑40 formula is tuned for V‑twin thermal conditions, while the included filter and drain plug washers simplify routine maintenance. Whether you service bikes at home or operate a small shop, this kit supplies parts matched to the bike’s lubricant and clutch performance expectations.

How does this oil work with Thunderstroke engines?

The semi‑synthetic 20W‑40 blend is formulated to withstand sustained high temperatures common in air‑cooled V‑twin engines and to resist oxidation and viscosity loss. Additives preserve shear stability and provide corrosion inhibitors for periods of storage. It’s designed to maintain consistent oil film and component protection during long rides and stop‑and‑go use.

• Viscosity: 20W‑40 optimized for air‑cooled heat profiles.
• Semi‑synthetic base for improved thermal resistance over conventional oils.
• Oxidation inhibitors and rust protection for extended storage.
• Shear‑stable additives to retain film strength under load.

Will this formula affect my clutch or transmission?

The proprietary additive package is balanced to prevent clutch slippage and to support smooth engagement. It helps protect clutch plates from glazing or warping during heavy loads, while maintaining predictable shift feel. This reduces the need for clutch adjustments related to oil choice.

• Clutch-friendly friction characteristics to avoid slip.
• Protects clutch components from wear and heat stress.
• Helps preserve consistent engagement actuation.
• Formulated to work with Indian Motorcycle powertrain tolerances.

What’s included and how many changes will this kit cover?

The kit supplies six quarts of Indian Motorcycle Semi‑Synthetic 20W‑40 motor oil, one OEM‑spec oil filter, and two drain plug washers. Six quarts typically cover a full drain and fill for Thunderstroke engines and leaves reserve for top‑offs. The included filter replaces the old unit to ensure filtration efficiency after the oil change.

• 6 quarts of semi‑synthetic 20W‑40 motor oil.
• 1 genuine Indian Motorcycle oil filter matched to fit Thunderstroke models.
• 2 drain plug washers for leak‑free sealing after service.
• Enough oil for a complete fill and small additional topping.

How should I use this kit for safe, effective service?

Perform the change when the engine is warm to help oil drain fully, then torque the drain plug and filter to manufacturer specs. Replace the drain plug washers and inspect for leaks after startup. Proper disposal or recycling of used oil and filter is important to meet environmental regulations.

• Warm engine for a full drain, then level on a stable surface.
• Install new filter and two fresh drain washers; torque to spec.
• Refill with the six quarts supplied; check level and top if needed.
• Recycle used oil and filter per local guidelines.

Who is this for: This kit is aimed at Indian Motorcycle owners and independent technicians who maintain Thunderstroke 111 and 116 air‑cooled V‑twin engines and want a single, brand‑matched solution. It’s convenient for riders who perform DIY maintenance and for small shops that need OEM‑aligned oil, filter and seals in one purchase.
