We've been doing it for years in many industries.

We tell customers if an engine's rings are sloppy, if beari ngs or liners are wear- ing, if there is fuel dilution, etc. And with- out even seeing the engine!

How do we do it? EM/PA-Engine

Maintenance through Progressive

Analysis.

And now EM/PA can be yours.

You send us samples of oil, and we put them through our unique, auto- mated and computerized system. Don't confuse this with regular oil analysis.

Mobil has developed a system of en- gine analysis so different, it's patented.

EM/PAgives you a cumulative report on each engine's condition. It notes the changes sincethelastanalysisand eval- uates them. When trouble is serious, we contact you by telephone or telegram.

Otherwise, we mail you a report.

EM/PA helps you maintain your en- gines at peak performance levels. It prevents engines from being taken out of service on "false alarms" and reduces maintenance costs by letting you schedule downtime in advance.

And for all this, EM/PA costs you nothing.

If you are a U. S. com mercial operator engaged in Great Lakes, rivers or coastal trade and want more informa- tion on how EM/PA can work for you, sendthe coupon.
