The biggest problem when picking a lubricant seems to be how do you tell just how well it works. I spent some time racing and building my own motors, this gave me the oppertunity to use different oils and measure the wear to internal components.The results were very interesting. In my opinion synthetics are the best in reducing if not eliminating friction wear and heat.Heat being probaly the worst thing to all component life spans. There are many different types of synthetics ,full polymer-resin being the best. I am holding back giving any set brand names.Beaware there are dfferences.Alot of people do mention price,but then how much does a motor or transmission cost in comparison. I have used synthetics for over ten years with excelent results in all types of aplications, if it takes lube I have put synthetics in it.I even had a old timer (65 years) in the Automatic Transmission rebuild world talk me into trying Synth motor oil in one of my automatics,three years later every thing is working great.Try small experiments at first untill you feel confident.
