⚙️ Oil Change Notes

Skill Level: EASY — 30–45 minutes. Warm the engine for 2–3 minutes before draining — warm oil flows faster and carries more contaminants out with it. Drain the old oil completely, replace the drain plug with a new crush washer, install a new oil filter, and fill with the correct quantity of Leichtlauf High Tech 5W-40 per your owner’s manual (typically 5.0–7.0L for most European 6-cylinder engines; 4.5–5.5L for 4-cylinder). Start the engine, check for leaks at the drain plug and filter, and reset the service interval counter via the instrument cluster menu.
