Oil pressure warning light on on a Kymco People 300 2026

Oil level too low

URGENT: as long as the oil pressure warning light stays on, DO NOT RIDE -- an engine without oil pressure destroys itself within minutes (rod bearings, camshaft). The diagnosis is confirmed: an oil level too low to maintain normal pressure. This is the most common cause and the simplest to fix. The fix, in principle: check the level on the dipstick (engine off, bike fully upright, after a few minutes' rest so the oil settles back down) and top up with a motorcycle oil that meets the manufacturer's specs -- the right viscosity grade (e.g. 10W40) and, for wet clutches, JASO MA/MA2 rated (never a car oil with friction-modifying additives, which will make the clutch slip). This is a basic job. Risk level: low as far as the work goes, but the context (oil warning light) is critical. On budget: a good quality motorcycle oil (Motul, Castrol, Elf, etc.) runs roughly 10 to 25 euros a liter. Key point: a low level doesn't happen on its own -- either the oil is overdue for changing and has burned off/evaporated, or there's a leak (gasket, hose, drain plug) or internal consumption (rings, valve seals). If the level drops quickly between checks, track down the cause. And if, once the level is topped up, the light stays on with the engine running, DO NOT RIDE: the problem is more serious (sensor, filter, pump) and needs investigating, or the bike needs towing. This tool helps you understand what's going on -- it doesn't replace a certified mechanic.

How to make the repair yourself

🟢 Within reach of any rider: no advanced mechanical skill or specialised tooling needed.

1. 1Shut off the engine immediately the moment the oil warning light comes on and stays on: don't keep riding, or you risk destroying the engine within minutes.
2. 2Wait 2 to 3 minutes for the oil to settle back into the sump, get the bike fully upright (not on the side stand, which skews the reading), and check the level on the dipstick (wiped then rested without screwing in, or read through the sight glass).
3. 3If the level is very low, below the minimum, or not showing on the dipstick at all, top up with a motorcycle oil that meets spec: correct viscosity grade (check your manual) and JASO MA/MA2 rating for a wet clutch. Don't use a car oil with friction modifiers.
4. 4Add oil in small amounts, rechecking the dipstick often, until you reach the maximum mark without going over (too much oil is also harmful).
5. 5Check the ground under the bike and the lower engine area: oil traces point to a leak (gasket, hose, a loose drain plug) that needs addressing, or the level will drop again.
6. 6Restart briefly and confirm the oil pressure light goes OUT within a few seconds of starting. If it stays on despite a correct level, SHUT THE ENGINE OFF again: don't ride.
7. 7If the light goes out and everything looks normal, keep an eye on the level over the following days/weeks: a rapid drop points to a leak or internal consumption that needs diagnosing.
8. 8If the light stays on with a correct level, have it checked (pressure sensor, clogged filter, oil pump) or have the bike towed: never risk riding without oil pressure.
