Car Maintenance 101 Reminder: On Oil Color

Although pop culture seems to portray car oil as something black and viscous, keep in mind that oil is not supposed to be black at all! Usually great quality oil should be fairly translucent and amber in color when you’re checking it with your vehicle’s oil dipstick. If you see that your oil is too thin or too thick, grainy with residues floating on top, or black (or near it), then your vehicle needs an oil change. If you’ve already had your oil changed recently, but it still looks somewhat opaque, then you may need a mechanic or a professional to have a good look inside your engine. It’s possible that the oil corruption is caused by a faulty part of your engine’s system.

If you need to replace your oil cap or some other part of your engine, then you’ll need to find a great auto parts or truck accessories provider. Conducting your search online helps you find the best parts providers on the market. Keep in mind that the initial price indicated on the vehicle part may have “hidden costs” that includes shipping.

    This is an old myth that is just plain wrong. The color of oil has no correlation to its effectiveness in cleaning and lubricating. In fact according to many leading manufacturers like Mobil, Pennzoil, and Castrol, dark oil means that the dispersant additives are doing their job and suspending carbon and dirt. Just check their web sites and product literature. The fallacy of this myth is also easily exposed by the fact that fresh oil in a diesel engine will turn jet black almost immediately due to the by-products of diesel combustion. If you’re going by this myth, you would have to change your oil every 3 hours to keep it “clean!” The only way to determine whether an oil is maintaining its viscosity and additive levels is through oil analysis. Don’t let a shade-tree mechanic (or blogger) tell you otherwise.

    is it ok to combine different kind of brands of oil for your engine? (i.e. castrol +pennzoil)
