Oil / LubricantsWritten by Kevin Schappell
I receive a lot of questions regarding oil and least understood part is number system used to rate oils. Oil weight, or viscosity, refers to how thick or thin oil is. The temperature requirements set for oil, by Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high). Oils meeting SAE's low temperature requirements have a "W" after viscosity rating (example: 10W), and oils that meet high ratings have no letter (example SAE 30). Oil is rated for viscosity by heating it to a specified temperature, and then allowing it to flow out of a specifically sized hole. Its viscosity rating is determined by length of time it takes to flow out of hole. If it flows quickly, it gets a low rating. If it flows slowly, it gets a high rating.
Take Care of Your BodyWritten by Kevin Schappell
The winter months can be tough on your body... your car body that is. Salt and chemicals used in colder climates can wreak havoc on your cars precious sheet metal. By doing a few simple things this winter, you can keep your car's body looking it's best. Put a good heavy coat of wax on your car before winter storms hit. This heavy coat will protect your paint from corrosive salt and cold temperatures. ·Wash underside of your car often during winter months. Salt and chemicals will collect under vehicle and slowly start eating away at your car. ·Skip undercoating unless you are buying a new car. Applying undercoating after a car has been on road for a year or two is pointless. The metal has already started to rust and there is bound to be water stuck in places it does not belong. Once you undercoat, you trap that water or rust and allow it to destroy your car.
