Should The Engine Be Warm Before An Oil Change?

You want to change your oil and it occurs to you, does it really matter if I change the oil after the car has been sitting, or should I change it after the car has warmed up? If you think about this logically, the answer becomes clear. When an engine warms up, the oil does too. This makes the oil flow more easily. An extreme example of this would be butter. The more you heat butter the more of a liquid it becomes. Also, since the oil will have been circulating while it warms up you will pick up more impurities that will be flushed out when you drain the oil.

You don’t want it to be too hot though. If the car has been running for 30 minutes on a highway and you drain the oil, you are going to get seared by a 300 degree liquid. Ouch! So, what is the best rule of thumb? Five minutes. Running the engine for five minutes will get your oil to the temperature and consistency ideal for an oil change.

Of course, the best advice of all is to come in and have us change the oil for you. No guesswork and we environmentally dispose of your used oil.
