D2o—Lancaster Farming, Saturday, October 27,1984 By: Mark Elliot Engine Division AlUfl-Chalmen Corporation MILWAUKEE, Wise. - Today’s high-output turbocharged diesel engines require proper care of their lubrication system if they are to deliver years of satisfactory performance. Let’s examine the functions and importance of today’s motor oil. What is the purpose of a motor oil? If you answered “to lubricate” you are only partially correct. Motor oils have four major func tions: 1. Clean - The motor oil must keep internal engine parts free from carbon and varnish that may excellerate wear due to increased friction or heat. 2. Cool - Motor oil acts as coolant for all parts that it comes in con tact with. Motor oil normally runs around 210*F. This cooling action helps control expansion of engine parts. 3. Lubricate - Yes, the motor oil must also act as a high quality lubricant. 4. Seal - In addition to the three items above, the motor oil helps seal seals by allowing the seals to retain a certain quantity of oil that keeps remaining oil from leaking out. Today’s motor oils are available in various grades and viscosities. Take, for example, the two cans of oil shown in “Oil Can 1” and “Oil Can 2.” Let’s break down the terms on oil can No. 1. Item S.A.E. 30 A.P.I. CD Description Society of Automotive Engineers; Viscosity of thickness at 212®F.; American Petroleum Cut Energy Costs 75%—Uses the drying power of fan forced air. No gas to buy. And the only electricity used powers the computer con trolled fan system. Reduced Shrinkage—Stmnk loss is cut up to 50% through natural moisture removal without high temperature heat. Better Grain Quality—With no high temperature heat to crack and damage grain, more starch, sugar, valuable nutnents and profit are retained.

Viscosity at 212*F computer from the 212° scale Viscosity at 212°F computer from the 212° scale. Now let’s compare the two motor oils. Do we know what the viscosity of oil No. 1 is at 0°? Not really. In the case of oil No. 2 we know that at 0° the oil flows or acts as a 15W and at 212° it acts as a 40 grade. We must remember that the W scale or the first designation of the multi-vis oil is taken at 0° while the second rating is derived at 212°F. Many people think that a multi vis oil such as a 15W-40 actually gets thicker as it heats up. Not true. The oil will become less viscous or thins out as temperature rises. All multi-vis ratings have done for us allowing a measurement of the motor oil both when it is cold for cold drinking and starting capabilities and warm Slash drying costs as much as 75% with the AeroDry" System 6® COOL CLEAN SEAL Item 15W 40 Description /e, r '-o\ ( 30 / OIL CAN NO 1 OIL CAN NO 2 for the needed protection when the engine is operating under full load. A.S.A.E. 30 oil simply tells us that oil will act as a 30 grade at 212*. We really don’t know for sure what its viscosity is at o°. Allis-Chalmers recommends both the S.A.E. 30 or a 15W-40 CD rated motor oil depending on the climate. All new engines shipped from the factory have a 15W-40 CD motor oil fill. See chart for recommended oil for your par ticular climate. The last and probably most important item in guaranteeing a long-lived engine is proper oil and filter change intervals. AUis- Chalmers recommends that the engine oil and lube oil filters should be replaced every 100 hours. This holds true on all engines that do not use a by-pass oil filtration system. ’♦*9 RED ROSE lUILDING SUPPLY CO V\ • Prices Subject To Change Without Notice • Delivery Available At Extra Charge Treated Timbers 4x6 6x6 Complete Line of Cannonball Sliding Door Systems! *lO *159“ PRE-HUNG SERVICE DOORS Turn Upside down, Turn Inside Out, All Out Of The Same 80x...

ANNAPOLIS A potentially important insect affecting corn has been detected for the first time in Maryland in 1984. The western com rootworm (WCR), a one-inch “beetle”, was recovered in specialized traps and represents a new State record for this pest. A network of traps baited with WCR female sex attractant was set up and maintained through a cooperative program involving the University of Maryland, Maryland Department of Agriculture, and USDA, APHIS. More than 100 traps were placed within 16 counties. WCR adults were recovered in the following counties; Allegany, Anne Arundel, Baltimore, Carroll, Frederick, Garrett, Harford, Howard, Kent, Montgomery, Prince Georges, Queen Anne and Washington.

In addition over half of the corn crop is treated with in secticides to control this pest. Damage on com by WCR is similar to that of other rootworms. The immature stages feed on com moots causing “goosenecking”, lodging and stressed plants. In recent years this pest has been expanding its eastern range; moving into Ohio and Penn sylvania. Its impact on Maryland com production is, at present, unclear. WCR has shown in creasing resistance to soild in secticides in the Midwest. Rainfall and soil surface texture influence its numbers within an area. There are indications that WCR may pose a more serious risk in the heavier soils in Maryland. Detection surveys will be continued Statewide in 1985. DISTRIBUTOR For former Kaiser weatherstrong roofing and siding now rolled by McElroy Metal Mill.
