I dont know about you, but I get a lot of emails from various organizations. A lot of it is not useful and comes from folks who dont take no for an answer. However, there are some real nuggets in the mix. One that I particularly like is Fleet Owner. Its a great source of information and subjects that are pertinent to our industry. Most recently, I read an article by Aaron Marsh on oil and additives. He really brings some good insights into the way progress occurs in the trucking industry and, by extension, the oil business.
In his article, Marsh raises questions about oil change intervals and viscosity grades. As I think about it, the recent changes in drain interval recommendations should be a major plus for heavy-duty trucking. The truth is that while every heavy-duty engine builder recommends oil change intervals of at least 50,000 miles, most truckers, especially those with small fleets and owner-operators, change oil at much shorter intervals. Engines that should have oil changes at about 30,000 to 50,000 miles are routinely being changed at 12,000 to 25,000 miles. Why is that?
