An engine is filled with parts that are constantly moving and rubbing together. This constant rubbing creates heat from all the friction. You need oil to flow through these moving parts so that it can absorb the heat and prevent overheating.
Oil that’s in good condition accomplishes its task. Old oil doesn’t and need to be replaced. Fortunately, overdue oil change symptoms are easy to spot.
There are so many different signs and symptoms that will show up and indicate your car needs an oil change and possibly a tune-up (see below for what a tune-up actually means).
When you take your vehicle in for an oil change, the service person will perform an oil and oil filter change as well as inspect your vehicle for leaks and other noticeable issues and then give you additional recommendations on what they think needs to be done.
However, you shouldn’t always depend on them to do this accurately because they might not always catch every issue. This is why you need to pay attention to the signs which indicate that you also need a tune-up of some sorts.
Below are the top 10 signs of your car needing an oil change and/or a tune-up.
If you’ve never seen clean, new motor oil before, it kind of has a bright amber color to it. But when oil becomes old and dirty from the build-up of residue particles in the engine, then it turns into a much darker, almost black color.
