Wix announces its Ecolast oil filter that is says can reduce oil drain intervals. The filter’s cellulose/polyester media is impregnated with magnesium oxide to reduce acids and maintain TBN.
According to Wix, by maintaing TBN levels the additive package in the oil is kept fresh and oil drain intervals can be extended.
The filter, currently in limited production, has seen two million test miles. It can be used for EGR or SCR engines with CJ4 oils. When switching to Ecolast filters, an oil analysis is needed to determine the new optimum oil drain interval.
