I must say, I pay enough for my hotrods and everyday vehicles that they feel like high dollar aircraft. I'm sure others would agree, which brings me to this point...when my slant 6 is straining at almost 130 mph in the 1/4 mile or the viper is at 170 on the freeway. Why would I take a chance with a product that might fail and send me into the ditch or wall? Oil is the life blood of your engine and spending a bit more for added security is well worth it. Remember now, the coolant only cools 60% of your engine and the rest is up to the oil. Oil is important! I have lots of stories about Amsoil but know one wants to hear about 40,000 mile oil changes and such. And I would get called on expressing my opinions and not facts. Although, I do know the people in the company, how hard they work and how much they believe in their product (and USA made).
Most of the Synthetic oils are good oils and you can't go wrong, I prefer Amsoil because of my history with them. I sell Valvoline dino in my shop for the non believers as well. Later
