Should detergent oil be used on an older vehicle? When changing the oil is it a good idea to use an additive that claims to clean the engine on older cars? Older vehicles that have not been taken very good care of or simply a used car that one does not know much about should be maintained with caution.
Here are two reasons not to use detergent oil or engine gunk removers on older cars unless you like to spend money possibly on a new engine.
Reason1: Older vehicles that have much mileage all have some gunk buildup. There are no shortcuts to fixing this problem immediately this did not happen over night and will not be undone over night.
Do not use detergent oil to help remedy a problem like this unless one may want to drop the oil pan after every oil change and clean the blow back screen. The gunk seems to settle here and then no oil can get out. This can cause the engine to over heat and lock up if not caught in time.
It is a better idea to change the oil more frequently this will clean the oil safer than additives.
Reason 2: Engine gunk removers that are put into the engine prior to an oil change are not good remedies either, they can also stop up the blow back screen. If these have been added from day one probably nothing will happen but if the engine is really dirty then the debris has to go somewhere. This somewhere is usually over the blow back screen on the oil pump.
Do not under any circumstances let an oil change facility talk you into putting any detergent oils in your vehicle or engine gunk removers. No matter how good they say they are without first checking the owner’s manual or the service center for your particular vehicle. These guys are under pressure to sell and they do not care about your car as much as they care about the bonus check at the end of the month.
Unless one knows the vehicle you are driving and have been having it serviced since day one. Stay away from ideas other people have about cleaning the engine and getting better gas mileage. Find an oil change facility that you trust and stick with them.
There is no substitute though for changing the oil yourself this way it is always done right.
