An oil's viscosity is its thickness or ability to flow, and is designated by those numbers and letters often found on container labels. Common viscosities to be found on the self serve rack of ser- vice stations are 5W30, 10W30 and 10W40. The Society of Automotive Engineers (SAE) assign the grades to specific oils, hence the label markings SAE 5W30. For instance a "5" grade oil is very thin, with the fluidity of tap water. A very thick oil, such as "40 or 50" grade has a consistency of warm molasses. Most modern automobile oils are multigrades, literally two oils in one package. The "5W" is 5W30 SAE designation is the oils winter or 0 Celsius viscosity rating. In oth- er words, this oil acts like a thin oil at low temperatures. The "30" des- ignation is the oils high tempera- ture viscosity measured at 100 Cel- sius. An SAE oil and a 5W30 multigrade should have similar thickness at 100 celsius. Modern automobile engines re- quire multigrade oils. At low tem- peratures a thin oil allows the en- gine to crank more easily and is easier to pump from the bottom of the engine. This being most impor- tant with the advancement of over- head cam engines. Many owners would be surprised to find out that most engine wear occurs on the ini- tial start-up. At 20 below zero a heavy oil has the consistency of mud and takes up to 60 seconds to flow through the entire engine. On the other hand, light oil doesn't of- fer the high temperature protection required to sustain severe use. Al Roflings checks the cool- ant strength of a vehicle at Exeter Toyota Ltd. A 50:50 ra- tio of water and antifreeze in your radiator is suggested to prevent your cooling system from freezing. Weather warnings Winter travel by automobile can be serious business. Be prepared. If you do n lot of winter driying in isolated regions, you might consider having a citizen's band radio. *911 is a free call to police and ambulance on your cellular phone and *CAA is a free call for Canadian Automobile Association emergency road service (for CAA members). Heed The Warnings Local weather offices of Environment Canada issue warnings of impending blizzards, heavy snow, freezing rain or drizzle, cold waves and winds. Know The Hazards Blizzard—The most perilous of winter storms combining falling, blowing, drifting snow, winds of 40 km/hour or more, visibility less than 1 kilometre, temperatures less than -10°C; duration, six hours or more. Heavy Snow—Ten centimetres or more in 12 hours, or 15 cm or more in 24 hours. Even less in temperate climates. Freezing rain or drizzle—An ice storm coating roads, trees, overhead wires, etc. with ice. Cold Wave --A rapid fall in temperature in a short period, requiring greater than normal protective measures. Winds—The cause of blizzard conditions, drifting, reduced visibility and wind-chill effects. Therefore the ideal oil would com- bine the flowability properties of a thin oil at cold temperatures and the load-bearing capacities of a thicker oil at high temperatures. In simple terms multigrade oil. Most of us have grown used to filling our engines with 10W30 or 10W40. Now manufacturers and oil companies are recommending 5W30. The reasons the Original Equipment Manufacturers now rec- ommend 5W30 is their desire to re- duce internal engine friction for in- creased fuel mileage. They simply want to use the lighter oil to in- crease their cars Transport Canada fuel consumption figures. Produc- tion costs of 5W30 is higher thus cost of a single litre is higher than than 10W30. Additives called vis- cosity improves are added to 5W30 oil to gain its wide range of thick- ness at various temperatures. These additives tend to break down quick- er adding the importance of regular scheduled oil changes for longer en- gine life. Recent major improve- ments in oils may result in universal use of 5W30, particularly as gov- ernments pressure the auto manu- facturers even better total "fleet" fuel mileage. The "Sarburst" has mysteriously appeared on the container of engine oil. The starburst symbol is the new symbol consumers will look for when they want to purchase engine oils that meet automakers require- ments. To qualify for the "Star - burst" cer- tification mark, an engine oil must meet SH stan- dards, as well as those for Energy Conserving II classification. While the starburst symbol reads "for gasoline engines" a notice printed on the reverse side of the container reveals the oils are also suitable for diesel engines. Autotnakers .contended that the previous.6stem_of oil certification lagged behind advances in vehicle technology and contributed to vehi- cle failure. Oil technology, they be- lieved was not keeping pace with engine technology. The American Automobile Manufacturers Assc. and American Petroleum Institute eventually collaborated and the re- sult is a new engine oil licensing and certification system. Only those oils that comply to this new testing can display the "Starbust" symbol. A word about synthetics or artifi- cial oils Synthetic oils are not re- fined from crude oil, they are spe- cifically engineered for high performance engines. They can give you superior low temp. fluidi- ty, better high temp. protection and a greater resistance to oxidation. Some synthetics contain an addi- tive that actually bonds to engine surfaces, providing an extra layer of protection. That layer is there before you start your erigine,so there is no metal to metal contact even at start-up. Synthetic oils can be mixed with conventional miner- al oils, they are fully compatible and they are recyclable. Synthetic oils can be more expensive because they are engineered to provide su- perior performance and protection compared to mineral oils. Whatev- er your choice, the important thing , to remember is check your owners guide for suggested oil to be used in your vehicle. Many manufactur- ers do not discourage the use of synthetic oils, although they are ad- amant in the scheduled duration of oil changes. Synthetic oil changes can be really expensive when fol- lowing the manu facturers rec- ommended oil change inter- vals.
