One of the main reasons lube oils have to be changed is that their additive packages become depleted over time. The new Donaldson Endurance Plus truck filters use a built-in additive replenishment container, which reintroduces a concentrated blend of additives to the oil. The spin-on filters, when used in conjunction with oil sampling and analysis, have the potential to significantly extend oil drain intervals and reduce maintenance costs and downtime according to the company.
