Can old oil cause a car not to start? While it might take a while, yes it could.
Motor oil is essential when it comes to keeping your engine lubricated. While your oil filter will sift through as much as it can, dirt, debris, and particles like metal shavings can build up in engine oil, increasing wear and tear on your engine.
As the oil gets thicker over time, it can also become harder to circulate the way it needs to.
Let old oil circulate through your vehicle long enough and often enough, and it’s possible you could end up with serious (and expensive) engine troubles. However, no or low engine oil levels are more likely to cause a car not to start than old oil is.
