Regular Oil vs Synthetic Oil -EricTheCarGuy

Visit me at: Lately I've been seeing a lot of posts over at the forum talking about switching to synthetic oil with less than ideal results. Instead of typing out the same answer over and over I thought I would make this short video to help explain my experiences with synthetic oil. I'm not saying synthetic oil is bad, in fact it has it's place but my opinion is that place is not in your 15 year old Toyota or Chevy. The reasons as explained in the video are that synthetic has different flow characteristics and can actually cause your engine to leak oil and run noisy. It's perfectly OK to run conventional oil of the correct viscosity and change it on a regular basis. You don't need to spend the extra money on synthetic oil if your owners manual does not call for it. I look forward to your comments on this.

Is Synthetic Motor Oil Better For Your Car?
Is synthetic motor oil better than conventional oil? Synthetic Motor Oil Myths - Thank you to Pennzoil for bringing me out to the 2016 Canadian GP and sponsoring this video!

A greater viscosity means more resistance to flow, or a thicker oil. A lower viscosity means a thinner oil. Before understanding the benefits of synthetic motor oils, like this Pennzoil Platinum derived from natural gas, we first need to understand the rating system used for motor oils. You’ll often hear 5W-30, or 0W-20 as ratings used in cars today. These are multi-grade viscosity oils, meaning their viscosity grade changes with temperature. The first number, followed by a W, is the cold rating (W stands for Winter), and this means the oil behaves like an SAE 5 grade motor oil (using 5W-30 as the example) while cold, but at operating temperature, at about 100 degrees C, it operates like an SAE 30 grade motor oil. Now 30 is higher than 5, so initially it may seem that the oil would get thicker at higher temperatures, which is obviously not the case. A straight SAE 30 grade oil will be thicker at lower temperatures, as will a 5 grade oil. Even though a 30 weight oil is thicker than a 5 weight oil, at 100C the 30 weight will be thinner than a cold 5 grade oil. Low viscosity at low temperatures is important, because this is where a significant amount of engine wear occurs, so it’s critical to maximize oil flow to protect the engine. At colder temperatures, thinner oils will flow better and thus offer better protection. For a conventional oil, for example while creating a 5W-30 oil, you’ll start with a base oil similar to an SAE grade 5 motor oil, and include additives to alter the viscosity rating. To improve low temperature flow, pour point depressants (PPDs) are added. To increase the viscosity at high temperatures, viscosity index improvers (VIIs) are added. VI improvers are polymers which expand in heat, making it more difficult for flow, thus increasing the viscosity. Synthetic oils, however, can have base oils which are already formulated as a multi-grade oil, meaning you don’t necessarily need additives, or as much additives, to alter the viscosity at different temperatures. The major benefit here is that additives tend to break down over time, so synthetic oils will maintain their original viscosity properties much better throughout the engine oil drain interval versus conventional oils. (Diagram illustrating viscosity vs temperature) If you were to plot two 5W-30 motor oils, one conventional and one synthetic, at the beginning of the oil change interval, they would have similar viscosity properties. At the end of the interval, however, the synthetic would act nearly identical to the original oil, while the conventional oil would be thicker at low temps, and thinner at high temps. Now does this mean that with synthetic motor oils you can extend your engine oil drain interval? No! It just means your engine is better protected throughout the engine oil drain interval. There are still additives (anti-wear, dispersants, anti-foam, detergents, rust inhibitors, corrosion inhibitors) which wear out over time, so you should always change at whatever interval your owners manual suggests.

Re: Regular Oil vs Synthetic Oil -EricTheCarGuy
Visit me at: I knew the original video would spark discussion and apparently it's caused quite a stir over at iATN. I also felt that some of what I said in the last video needed clarification. For those reasons I've made this Re: video. I'm not going to claim to be an expert on oil, I'm just speaking from personal experience. I still don't think I'm done with this topic and I invite any 'experts' who wish to express their opinions on this topic to join me in the next video(s).
