This used to be the case, when automatic transmissions were relatively new. But recent advances in the technology (like the continuously variable transmission, which offers an infinite range of gear ratios) eliminates the advantage of manuals, and in some cases puts automatics ahead.
Another expensive mistake. Most vehicles run fine on regular-grade fuel (87 octane). Filling these cars with premium won’t cause damage, but it won’t improve performance, either. Higher-octane fuels are less likely to create pre-ignition problems, so they’re usually used in hotter-running, high-compression engines.
The pounds-per-square-inch figure on the side of the tire is the maximum pressure that the tire can safely hold, not the automaker’s recommended pressure, which provides the best balance of braking, handling, gas mileage, and ride comfort. That figure is usually found on a doorjamb sticker, in the glove box, or on the fuel-filler door. …

Despite what oil companies and quick-lube shops often claim, it’s usually not necessary. Stick to the service intervals in your car’s owner’s manual. Under normal driving conditions, most vehicles are designed to go 7,500 miles or more between oil changes. Changing oil more often doesn’t hurt the engine, but it can cost you a lot …

Photo Credit: wikipedia Engine oil that turns black is actually a sign that the oil is working. Modern engine oils contain detergent-dispersant additives that keep engine internal parts clean by removing carbon deposits and maintaining them in harmless suspension in the oil. It is better to have the carbon deposits in the oil so they …

# 1 Subwoofers have an RMS rating Speakers actually have a very complex thermal compression relationship and certainly can not be quantified by just one or two numbers typically called RMS and Program or Peak. Because voice coils in traditional drivers are inherently resistors, any amount of voltage generates some amount of heat which …
