Having recently purchased a 1981 car with a four-cylinder engine, I read E. F. Lindsley's article "Tough New SF Oils" [PS, April] with special interest. But I was confused by the statement that thinner oils help overcome the two major types of engine friction when it was later said that one of their disadvantages was increased engine wear.

Last year Suzuki delivered an explosive punch to the big-bore performance class with the GS 1100. It immediately became king of the super-bikes. This year Kawasaki landed a hard counterpunch: the GPz 1100. Recently I had a chance to ride it at Riverside Raceway in Riverside, Calif.

E. F. LINDSLEY
Author Lindsley spent 25 years as the national director of technical and field services for a major manufacturer of diesel engines. Late in 1977 Oldsmobile started selling the first diesel automobile ever mass-produced in America. To many eager motorists, buying it seemed a way to enjoy big-car comfort and small-car fuel economy.

This solar power plant using a central tower, in Adrano, Sicily, is the first in the world to feed electricity into a national grid. The one-megawatt plant has a reflector field of 182 heliostats, or sun-following mirrors. They focus sunlight onto a steam generator at the top of the tower.

I recently acquired a 1978 Ranchero 351 two-barrel in good condition at 22,000 miles. But I have had to replace the electronic control module three times. The parts store has replaced the modules without any argument. Could I be getting defective modules, or is there something in the ignition system that's blowing the modules?

This month, we’ve selected four significant new models not previously tested by PS: Audi 4000 5+5, Datsun 810 Maxima, Renault 18i, and Toyota Cressida.

When Klingbeil set out to build his own solar domestic-hot-water heater, he hated to bother with costly freeze-protection equipment or the complexity of an antifreeze-fluid system.

Just a year ago, everyone was agog over the latest marvel in miniaturization: Sony’s Walkman—the first high-fidelity stereo cassette player small enough to fit into your pocket [PS, July ’80]. The Walkman—like its many imitators since—was a "play only” design.

V. ELAINE SMAY
In the mid 1970’s, NASA began taking a fresh look at what seemed like an anachronism—the propeller. Reason: Turboprop planes use a lot less fuel than turbofans (jets). Goal of the program: a turboprop that would fly as fast as a jet (0.7 to 0.85 Mach) at similar altitudes (35,000 feet and above) and carry an equal number of passengers in equal comfort.

After a summer soak, your dip into the pool will be that much more refreshing. And at the end of the season—when it’s too cool for the pool—the tub extends your outdoor fun.

Sun-shading shutters do more than block heat

A. J. HAND
If you buy rolling shutters solely as energy-saving devices, you’re going to be disappointed. Sure these tough, hollow-slatted external blinds do an excellent job of blocking most summer heat. But during winter they don’t perform as well, (rood insulating shades mounted inside your home may give you three times the R-value at half the cost [PS, March].

Does your car idle like a bucking horse? If so, don’t ignore it. Rough idle is a sign that the engine isn’t running as efficiently as it should—which can mean higher fuel costs. One dead cylinder in a four-cylinder engine, for example, causes rough idle and wastes 25 percent of your gas.

The guide bar and chain are the parts that affect performance most—and that can become hazardous if ignored.

Many of our most valued possessions are difficult to safeguard. Cameras, typewriters, china, silver, guns, heirlooms, and furs, for example, are too bulky to hide or to fit into a home safe.

Especially these days, when inflation continues to shrink disposable income, it’s important to make intelligent purchases. And with the cost of furniture at an all-time peak, each piece you buy must be built to last. But how does a shopper identify quality, since much of the industry seems determined to fool him—with plastics masquerading as wood, hardware designed for initial appearance rather than durable function, and corner-cutting rampant everywhere it won’t show?

Merely touching the braking surface of a pad, shoe, drum, or rotor during installation can cause unequal braking later. This is because oil from your fingers is transferred to the parts when you touch them.
