choosing a Muligrade oil

I have heard that you should use a multigrade oil with the narrowest band of viscosity that is appropriate. Is this so?

Yes, in the winter base your decision on the lowest temperatures that you will encounter and in the summer the highest temperature that you expect. In general the greater the oils viscosity range the more the oil is prone to viscosity and thermal breakdown, do to high polymer content. A 10w-40 and a 15w-30 require a lot of polymers which is what they add to an oil which allows it to get thicker when it gets hotter, but it does not lubricate. Group III and group IV oils use polymers in order to achieve that range of viscosity. Polymers also burn with forms ring sticking deposits and other problems. The more polymers there are the less oil there is in the container to lubricate your engine. Overall it’s best to avoid polymers, and do that by using group V oils.

Fuel injector cleaners and gasoline additives- Save Gasoline!

I have heard that injector cleaning and use of a gasoline additive can help increase fuel mileage, is this so?

Yes, fuel additives help prevent carbon buildup inside the combustion chamber, and on the back face of the valves. These rob the engine of power, which means less gas mileage. So clean the injectors or use a gasoline additive that keeps the injectors clean, will help clean off the carbon and that will improve engine efficiency, which will means better gasoline mileage for you going down the road.

Sport utility vehicles in accidents

I have heard that Sport utility vehicles or Suv’s if driven inappropriately are more likely to rollover or be involved in an accident then passenger cars, therefore it is a myth that large SUV’s are safer then passenger cars. Is this so?

No, This assumption that large SUV’s are safer is based only on rollover statistics which are not enough to make such a blanket statement like that. The crash risk of death injury is the greatest in a passenger car that is involved in a frontal or side impact crash. In frontal crashes more than 6 passenger car drivers die for every driver killed in a van or pickup truck. A 6 to 1 ratio. More than 4 passenger car drivers die for every driver that is killed in an SUV.

Particles in serpentine belts

The buildup of particles of the serpentine belt between the belt ribs is usually caused by inadequate belt tension. Is this so?

Yes, it could be the cause of inadequate belt tension, misaligned pulleys or pulleys that are wobbling, but mostly it is caused by insufficient belt tension.

Henry Ford did not..

I have heard that Henry Ford did not invent the automobile, nor did he invent the assembly line. Is this so?










Yes. The gasoline powered car was invented by two different men in the late 1800's, Gottlieb Daimler and Karl Benz, working independent of one another. In order to fulfill a government contract to make muskets, EliWhitney pioneered the assembly line process 100 years before Ford.
