How long can oil sit in an engine before it goes bad?

Simply put, the shelf life of conventional motor or “lube” oil is up to five years. It’s not something that goes bad in a couple of months. It’s impossible to predict exactly how long motor oil shelf life is because petroleum stability (how well it resists change in its properties) is situation-dependent.

Can not changing oil damage engine?

Oil will break down over time due to high temperatures in the engine (known as thermal breakdown). By not changing the oil, particles already in the oil will begin to settle and cause corrosion.

How long can a car run without oil change?

Due to this, cars can generally go 5,000 to 7,500 miles before needing an oil change. Furthermore, if your vehicle uses synthetic oil, you can drive 10,000 or even 15,000 miles between oil changes. However, keep in mind that these numbers are just general guidelines.

What happens if you don’t change the oil in your car?

If you let the engine run with low oil levels you put your car’s engine at risk. The piston rings could fry and your car could breakdown.

If your car burns oil faster and faster that means its lifespan won’t be long unless you plan for a full rebuild eventually.

What happens if you leave the oil cap off after service?

It has a plug underneath that is used to drain the oil out. So leaving the cap off may splash a little oil around the engine bay, but will not cause a loss of all the oil. Leaving the plug out means no oil was added after the service, or if it was, it flowed straight through and would have left an obvious puddle of oil.

What happens if you drop all the oil and coolant?

I personally dropped all the oil and coolant from a Rover K-series engine (in a scrap car) and the engine took a good twenty minutes of very hard abuse (redlining / rev limiter / dumping the clutch in 1st) before expiring. That said, it may have cause a significant amount of wear which may not show itself for several thousand miles.

How often should I change the oil in my car?

For most cars, it is highly recommended for you to change the oil every 7,500 miles or so. If your car is newer you might be able to go longer before changing your oil.
