HOUSTON – A thousand trucking companies went out of business in 2008, and fuel costs were a major factor, a lubricant executive said. Replacing 15W-40 with synthetic 5W-40 diesel engine oil can help improve energy efficiency, but it can be a tough sell to fleet owners.
I wouldnt use 5W-anything in my lawn mower, one fleet owner told me, Mark Betner, product manager for heavy duty lubricants with Citgo Petroleum Corp. in Houston, relayed to the National Petrochemical and Refiners Association International Lubricants & Wax Meeting herelast month. Beware of preconceived ideas about 5W oils, he said. Youll encounter many when you try to introduce synthetic 5W-40 engine oils to the heavy duty sector.
