You'see'a lot more in an engine oil when you made the oil in the f irst place.

Reliability in oil analysis, plus proper follow-up in the field, can help you save thousands of dollars in less downtime.

That's exactly what you can get from Mobil EM/PA (Engine Maintenance through Progressive Analysis).

Since we made the oil formulations and additive packages in the first place, we can best tell whether something's gone wrong. Not knowing the oil com- ponents and additives can cause misinterpretation of an oil analysis report—and this can mean false alarms.

We're also different because we double-check the used oil you send us with an unused sample of the same oil formulation. This means greater accuracy in reporting any alarming changes in the oil.. .or in your engine.

And, if our labs do spot a problem, we don't leave you out there alone with it. Your Mobil representative will come right to your job site to work with you to solve it.

If we can't save you money, we don't deserve your business.
