Fresh oil is the cheapest insurance for your Royal Enfield Meteor 350 engine. The Meteor 350 uses 15W-50 (API SL, JASO MA2, semi-synthetic) — the right viscosity matters more than the brand. The sump holds 2.2 liters and should be changed with the filter. Change it every 6200 miles, sooner if you ride in dust or heat.
An oil change on the Meteor 350 is a 30-minute job with basic tools. Warm the engine first — warm oil drains faster and carries debris with it — then follow the steps below.

How to change the engine oil, step by step
- Warm the engine — run for 5 minutes, then switch off.
- Place a drain pan under the sump and remove the drain bolt.
- Replace the oil filter — unscrew the old filter, oil the new filter’s seal, fit it hand-tight.
- Fit a new crush washer on the drain bolt and refit it to the correct torque.
- Refill with 2.2 L of 15W-50 oil through the filler cap.
- Start and check for leaks — run for a minute, then stop and inspect the drain bolt and filter.
- Check the level — use the sight glass or dipstick with the bike upright; top up to the full mark.
Common mistakes to avoid
- Over-tightening the drain bolt — stripping the sump thread is an expensive mistake; use a torque wrench.
- Forgetting the crush washer — a reused washer leaks — always fit a new one.
- Using the wrong viscosity — 10W-40 won’t protect as well at high temperatures; use 15W-50.
- Overfilling — too much oil causes foaming and can blow seals — fill to the mark, not above it.
