Freight volume drop presents unique maintenance challenge

June 2, 2020

With rates and freight volumes both currently sitting at historically low levels, nearly 30% of respondents to a CCJ survey that measures the coronavirus’ impact on motor carriers said they have reduced driver count.

With no one sitting behind their steering wheels, many fleets are parking some units until trucking conditions improve. But there’s more to mothballing a unit than simply pulling the air brake and turning off the ignition if the tractor is to return to service in mechanically sound condition.

As long as the cooling system is full and has been well-maintained, it should be fine for long-term storage, said Jami Melani, field engineering/heavy-duty technical services manager for BP/Castrol. However, engine oil will continue to degrade even if the engine isn’t running.
