Debunking Myths: Sythetics Edition

Jennie McRae - Tuesday, October 28, 2014

        Been thinking about converting from a conventional oil to a synthetic? You’re not alone. Ever heard of some possible negatives to making that switch? You’re not alone on that one, either! Some claims you have heard may be warranted, but others are down-right, plain and simple just not true. Let’s debunk some of the myths you might have heard about synthetic oils:

 

Myth #1: Once you switch to a synthetic, you will always have to use one.

 

         Normally, myths are at least rooted in truth—this one, however, is not. Most all synthetic oils use a base oil that is derived from crude oil. (We use the word "most" because Pennzoil is challenging the standards on that one lately… click here for more information!) There are also a variety of synthetic blend oils out there to choose from if that is what suits your needs. Our point is this: you should not be scared to mix synthetic with conventional because it’s already being done by every brand you may have used. As long as the synthetic oil is meeting the OEM requirements set out in your owner’s manual and your seals are in decent shape, you can switch back and forth to your heart’s content.

 

Myth #2: A synthetic oil will cause leaks.

 

         We’re going to give it to you straight: this myth is based in fact. Early synthetics were made from esters which were hard on neoprene seals. However, synthetic oils have come a long way since the 1970’s—of many improvements made to synthetics over the years, a huge one is that they are much easier on seals. And, while synthetic oils will not create any leaks, you can be sure that they will find one. Because synthetics are so streamlined molecularly, they have no mercy for cracked seals. Synthetic oils may even clean gunk and deposits from your engine which is a very good thing—unless those deposits are acting as spackle on some questionable seals.1 If your vehicle has over 75,000 miles, you should be using a high mileage engine oil. 2

 

Myth #3: You should break in a new engine with conventional before you start using a synthetic oil.

 

 

        False. There is no manufacturer, that Central Oil & Supply is aware of, that makes this claim. Corvette, Cadillac, Volkswagen, Hyundai, and many other manufacturers’ cars come from the factory with synthetic oil.3
