What happens if you don’t change the oil in time?
4 min readFailing to change the oil in time is one of the most expensive savings in motoring. Old oil loses its properties and stops protecting the engine.
What happens to old oil?
Worn oil thickens, forms sludge and deposits, lubricates worse and carries away heat less effectively. Contaminants clog the oil channels, and friction increases.
Possible consequences
- Accelerated wear of the bearings and crankshaft
- Clogged oil channels and a drop in oil pressure
- Overheating and a risk of engine seizure
- A repair running into several or tens of thousands of zlotys
An oil change costs a fraction of repairing an engine destroyed by old oil.
Don’t risk the engine. If the change is overdue, book a fresh call-out oil change — fast and with no queues.
