What Happens When You Don't Change Your Oil Part 2
This is part 2 of what happens when you do not change your oil. This car is only 3 years old and has 135k miles on it.
Oil change scams: Hidden camera investigation on what really happens to your car (CBC Marketplace)
CBC Marketplace finds aggressive upselling and services paid for but not performedTo read the full story: http://www.cbc.ca/1.2418675. Originally broadcast Nov 8, 2013. When you trust someone else to take care of your car, can you trust that they're not taking you for a ride? Our undercover investigation reveals ripoffs at a popular oil change chain. We're going in for the advertised $19.99 oil change, but you won't believe the charges we end up with. And did they even do the work? We go up on the hoist to show you what’s really going down at these oil change shops.

Engine Running NO OIL - NO SUMP - Seized Soild on Camera
Messing with a Mitsubishi Lancer There are loads of videos where people run an engine at full rev with no oil in it, and the engine seizes. Running it a medium rev, I wanted to see how long it would run with no lubrication, and I was surprised. However if the car was driving and the engine was under load, it would be dead in minutes!
Is Synthetic Motor Oil Better For Your Car?
Is synthetic motor oil better than conventional 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.
