Castrol CRB NG 15W‑40
Excellent Oxidation and Nitration Protection
Castrol CRB NG 15W‑40 prevents sludge, varnish, plugged filters, and deposits that occur in
natural gas engines as a result of oxidation and nitration.
Outstanding Wear Control
CRB NG 15W‑40 prevents cylinder liner and cam tappet wear by providing excellent
protection against ash deposits over an extended drain interval. CRB NG easily passes the
Cummins C8.3G test at the standard 200 hours, and also passes when extended out to
400 hours.
