Automotive Lubricant

Tighter emissions

engines and changing
engine designs

higher quality engine oil performance category: API CI-4,
to meet increased engine oil performance requirements.
Mobil Delvac MX 15W-40 exceeds the requirements of
API CI-4 offering higher levels of engine protection to help
minimize maintenance costs and extend engine life.

challenge on diesel engine lubrication. You have come to
expect that from the worlds leader in advanced lubrication
technology.
