Question:

Dear Kevin,

My name is Dan. I am an amsoil dealer. I was at a county fair and a guy came up to me, must have thought I needed an education. He said that oil gets thicker in viscosity, When it gets hot, because the molecular makeup. WHAT is this guy saying? He said that is why multi- viscosity oil has two numbers. I was told by another, that the viscosity rating is based on the gaps in the engine crank bearings. This came about by racers having there engine tested by engine manufactures. Can you shed some light on this for me. Personally I think their full of it.

The first guy is right ! Your engine needs the thinner oil when it’s cold and the thicker oil when it’s hot. They do have additives that make the oil thicker as the engine heats up.

Most people have heard of synthetic oil for your engine, but did you know that you can get synthetic oil for your transmission, and rear axle? The guys at Royal Purple http://www.royalpurple.com/ have a full line of lubricants for your car. The main advantage of using synthetics in all your moving parts, is the reduced friction. You can free up horsepower and save money with increased gas mileage. I changed all the fluids in my Dodge Stealth and noticed an instant improvement, plus I knew my car was being protected from friction with the best lubricants available.

I have been running synthetic oil for a few years in my cars and love it. The longer oil change intervals and better lubrication are the major advantages. I have a good series of articles on the site which help you learn about synthetic oil. There are many myths out there about synthetic oil and you should be aware of the truth. I will only run synthetic in my performance cars, and usually use Mobil 1 or Amsoil. Royal Purple has a good line of products also.
