With today's fuel prices, a nationwide focus has shifted to vehicles that can squeeze more miles out of a tank of gasoline.

And as American automakers push to produce cars and trucks sporting better gas mileage and fewer emissions, one local manufacturing company has created a fuel-saving converter that has proved it can produce better mileage while also helping improve air quality.

At Blumenthal Cos., a 59-year-old Oklahoma City company that remanufactures engines, a tested converter that boosts fuel savings came about almost by accident as the company grappled with extending the transmission lifespan on fleet trucks used by some of its customers.

Robert Yarbrough, senior general manager of Blumenthal's engines and automatics division, and employee Richard Walker were the chief designers who collaborated on the idea three years ago for a converter that would keep heavy-duty truck running longer.

"At UPS, they were burning up transmissions at 40,000 miles, and the first converter we designed prolonged that to 120,000 miles,” Yarbrough said.

Test results show big savings
From that initial discovery of fuel savings for big, half-ton trucks, next came designs that also would improve the performance of smaller, everyday vehicles.

The company acquired a patent for its power lock converter system a year ago and since then has put it through tests on different cars and trucks to gauge actual savings. What they found was an increase in mileage from 24 percent to 59 percent depending on a vehicle's make and model.

Trucks have been the focus, Yarbrough said, "because there are so many more, and they are the biggest gas guzzlers.”

The company invested $30,000 for the converter's patent and almost $275,000 just for converters for Ford engines. Its research determines that, so far, the converter can be installed in General Motors vehicles, Ford and Chrysler sport utility vehicles and rear-wheel drive cars, and Dodge diesel trucks.

At $695 installed, the converter's price "will pay for itself within six months in fuel savings,” Yarbrough said.

Although Blumenthal just now is starting to market the converter, the company already is targeting cities and law enforcement agencies as potential customers. The converter is installed in two cars at both the Stillwater and Duncan police departments, as well as two cars used by the Oklahoma Highway Patrol.

What's next for Blumenthal?
All the converter's parts are made in Oklahoma, Blumenthal marketing director Harry Brown said, but the company wants to take the product beyond state lines.

"We're trying to get companies like Napa Ford to pick this up to get the converter into the automotive aftermarket,” Yarbrough said, and the company is in discussion with Ford Motor Co. and Mopar, the parts division of Chrysler Corp. "The more we sell, the more we can put into research and development.”

As the company works to bring heavy-duty engine applications to more car brands, it is also involved in research into other areas, including hydrogen fuel alternatives.

How does one obtain this converter?
Thanks;

Bryan, The converter minizes the slippage designed into the automatic transmission. The OE design may have 16% slippage, with our converter it changes that slippage to 7-9% and engsges the 'lock-up' in the converter quicker. The gas savings are recognized due to this quicker lock-up and less slippage. If you have questions please feel free to email me at hbrown@blumenthalmfg.com and get a plant tour, the public - our customers - are always welcome to come see us. We appreciate you for responding to the article. Harry Brown, III
