When to use Winter tires and when to use All-season tires?

Winter tires are tires that you would use during winter conditions and all-season tires are also called 3-season tires. All-season tires are ideal for Spring, Summer, and Fall. You should use winter tires during harsh winter conditions with lots of snow, freezing rain and ice as these tires are designed to perform in these harsh conditions. All-season tires should be used when the temperature is above 7-degree celsius and during warm, dry and wet conditions.



What is a Spark Plug? What does it do?

A spark plug is a device that delivers electric current from the ignition system to the combustion chamber. A spark from a spark plug is used to ignite the compressed air-fuel mixture in the combustion chamber. Initially, in the combustion chamber, the piston moves down to create a vacuum as to draw in the air-fuel mixture, the piston then moves up to compress this air-fuel mixture and the at the very last second a spark from the spark plug ignites this air-fuel mixture sending the piston down to the power cycle, the piston then moves up to get rid of the exhaust in the upward exhaust cycle.

Understanding Engine Oil? What does 10W-30 mean?

10W-30, Represents two SAE numbers, 10W and 30.

10W represents the first SAE number and is associated with the SAE number for cold temperatures. An SAE number is a measurement of the viscosity or thickness of oil. Why is this number important? This number is important because in cold temperatures you need the viscosity to be thinner as oil is usually thicker when cold and therefore will not be able to properly lubricate the engine and its components. The lower the first SAE number, the thinner or more viscous the oil will be at lower temperatures or during startups.

30 represents the second SAE number and is associated with the engine running temperature or at 100-degree celsius. Why is this number important? This number is important because when the engine is running, the oil is hot and therefore already thin or viscous and therefore if this number were to be any lower, say like 20, then the oil will be too thin and will not be able to effectively lubricate the engine and its components.

What is the Difference Between A Gas Engine and A Diesel Engine?

Both Diesel and Gas Engines have the intake, compression, power and exhaust stroke cycle, where they differ in is the fuel type. Gasoline evaporates quickly in air and mixes well with compressed air and therefore can be easily ignited by a spark from a spark plug. Diesel fuel, on the other hand, is engineered to ignite at a high cylinder pressure without the need of spark plugs.
