The value of proper oil changes
The first thing we need to be clear on is that changing oil at the proper time is the best thing you can do for the life of the engine. You can use fuel additives to keep the injectors clean. You can use the right octane rating of gasoline. You can do lots of things, big or small. But changing the oil within the recommended period (every 5,000 – 7,000 miles for most manufacturers) is the number one thing that will keep any car or truck running well for its entire vehicle life.
Not changing your oil often enough allows harmful dirt, particulates and acids to degrade key engine parts. It also increases the buildup of sludge and lessens the oil’s ability to dissipate heat, increasing engine stress. So not changing your oil often enough is a bad idea. But what effects does it have on performance?
Performance? What’s Performance?
When we say ‘performance’, we mean gas mileage primarily. Running an engine on old, sludgy oil will cause a decrease in fuel economy. How much? The book’s still out on that; we’re not aware of any good automotive engineering studies that have quantified the effect.
But when oil thickens and becomes sludgy because it’s past due to change, it loses some of its lubricity and makes the engine work harder. Old oil will break down due to exposure to heat, losing its ability to maintain the viscosity needed to do its job. Without the right viscosity, the oil loses the essential ability to get where it needs to go in the engine. The engine runs hotter and less efficiently, robbing the engine of both gas mileage AND horsepower.
