Just like any engine, you must change the oil and filter regularly, using good-quality oil.
Always fill your tank with clean fuel from reliable stations to prevent damage.
Keep an eye on the engine's cooling system to prevent overheating, and make sure the air filter is clean for the best performance.
Lastly, warm up the engine before driving in the cold and let it cool down after long trips.
