Hello CA! Duke Here and today's vehicle care topic is: Synthetic Oil vs. Petroleum Based Oil. So let's watch my video below and bet barkin' on this slick subject!
Synthetic motor oil is a substitute for petroleum based oil. If you aren't currently using it, why not? Synthetic motor oil maximizes engine power and fuel economy. To see why, we'd need a microscope, so we'll have to settle for using our imaginations. The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is slipperier, a pile of pencils or a pile of marbles?
Synthetic motor oil lubricates better because there's less friction. This results in myriad benefits: better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn't sludge up like conventional oil so it prevents those small oil passages from clogging up. (We see that too often at Allied Auto Works in Los Altos.)
Some manufacturers are extending oil change intervals for many models. The added protection of synthetic oil covers you for these longer intervals. Talk with your Allied Auto Works service advisor about how you drive in and see if he thinks you can benefit from synthetic oil for your vehicle. Also ask about the appropriate oil change interval for synthetic, because it may very well be longer than for conventional oil.
Most of us have a busy life and occasionally miss an oil change; go ahead, admit it. Since we're not perfect, doesn't it make sense to use a motor oil that's got your back?
What about price? Petroleum based oil may appear to win out on this point, but let's consider all the facts. Although synthetic oil costs more, it lasts longer, protects your vehicle engine better and increases fuel economy. You'll likely save money in the long run. If you're serious about making your vehicle last longer, consider using synthetic motor oil.
