Description
This McLaren Oil Change Seal Kit provides the O-rings and crush washers required during routine oil service on many McLaren twin-turbo V8 models, including the 570S, 600LT, 650S, 720S, 750S, and 765LT.
McLaren Oil Change Seal Kit
This McLaren oil change seal kit includes OEM-spec sealing components used during routine engine-oil service. The kit includes high-temperature nitrile oil cooler O-rings along with the copper and aluminum crush washers used at key sealing points in the oil system.
Many McLaren models share the M838T 3.8L or M840T 4.0L twin-turbo V8 engine platform. Therefore, the same oil-service sealing components fit a wide range of compatible McLaren vehicles.
In addition, this seal kit is ideal for owners who already have an oil filter and only need the O-rings and crush washers required for their next oil change.
Why Replace the Seals During a McLaren Oil Change?
Oil-system O-rings and crush washers create seals between components opened during routine service. Replacing these components helps reduce the possibility of oil leaks after you reassemble the oil system.

⚙️ Why Nitrile (Buna-N) O-Rings Matter
McLaren twin-turbo engines expose oil-system seals to engine oil, heat, and demanding operating conditions. Therefore, choosing the correct sealing material matters during routine maintenance.
This McLaren oil change seal kit uses high-temperature nitrile, also known as Buna-N, for the oil cooler O-rings.
- Excellent resistance to engine oil
- Good temperature durability
- Long service life when used in appropriate applications
- OEM-spec sealing performance for compatible McLaren oil systems

🏎 Designed for McLaren Twin-Turbo V8 Engines

It supports vehicles using the M838T 3.8L twin-turbo V8 and M840T 4.0L twin-turbo V8 platforms.
Because many McLaren models share these engine platforms, one properly matched seal kit can support oil service across multiple compatible McLaren applications.
🔁 Recommended Oil Service
Follow the service schedule specified for your McLaren model and driving conditions. However, vehicles exposed to demanding driving, track use, high temperatures, or other severe operating conditions may require more frequent maintenance.
