Why does your engine oil look like jelly?

If your engine oil looks like jelly, it may be due to contamination or degradation, often caused by high heat or the presence of moisture. This can lead to the formation of sludge, which thickens the oil and impairs its lubricating properties. It could also indicate that the oil hasn't been changed in a long time, allowing dirt and debris to accumulate. It's advisable to have the oil inspected and changed promptly to prevent engine damage.
