KL "If it weren't for Mobil we would have lost three engines the first half of this year"

Roy Gaston takes an oil sample for EM/PA analysis aboard the McAllister vessel Marjorie B

The port engineer who said that is Tony Oven of McAllister

Brothers, Inc., which runs a fleet of 46 tugs in and around

New York harbor, Puerto Rico and the Gulf. Those three engines are 2000-horsepower. 16-cylinder power plants that take 30 to 40 thousand dollars to overhaul, a lot more to replace.

Mobil used EM/PA—its computerized program—to chemically analyze samples of oil from McAllister engines.

Finding a fuel oil dilution of seven per cent in one engine,

Mobil diagnosed the cause as a leaky fuel jumper line, and saved the engine from a possible breakdown that could have cost ten days' downtime and probably close to $70,000.

In a second vessel. EM/PA spotted a high chromium count that meant leaky liner seals. On a third, high iron traces revealed broken harmonic balancer springs.

Says Tony Oven: EM/PA has reduced breakdown by 60 to 70 per cent. And we save on oil because we change it only when EM/PA tells us:

Says Mobil: Ask your Mobil man about EM/PA to keep fromgoing overboard on engine breakdowns and repairs.
