Vios Oil Pressure Warning

I've got a 2014 Toyota Vios with a gasoline engine, and I'm running into a bit of a headache. I've noticed the oil pressure warning lamp lighting up occasionally, along with the warning light in the speedometer. My mileage is sitting at 147239 km. I'm suspecting it may be oil contamination, but I'm not sure how severe it is. Anyone else had similar issues?

Sounds like you might have an oil pressure issue, possibly caused by the oil contamination. Is the oil level correct? When was the last time you changed the oil and filter? Have you noticed any oil leaks around the engine?

Oil level seems okay, and I changed it roughly 10000km ago with new filter. Haven't spotted any obvious oil leaks. Could exceeding the maintenance interval cause such a drastic issue with the oil, or should I be looking at something else?

Yes, exceeding the maintenance interval by that much could definitely lead to oil contamination and a drop in oil pressure. It's possible the oil has broken down and isn't lubricating properly. You should probably take it to a workshop to have it checked out before it causes engine damage.

I took your advice and brought it in. Turns out the oil was indeed heavily contaminated due to me pushing the service interval. They flushed the system, replaced the oil and filter, and now the warning lights are gone. Cost me 165€, but better than engine damage. Appreciate the help!
