believe it or not!

There was a big study done on the regular vs synth oils. There was no wear difference on the engines using synth oil over regular oil. The differences came in when the engines were driven hard, in dusty conditions or steep hills or if oil was changed every 4-6,000 miles. All oil is 20% additives and 80% lubricants. It is the additives that determine quality of oil. The synth oils are a chemicaly derived oil while the others are naturaly derived. If you don't race, and drive you car normaly then the synth oil is a waste of money. If you race or drive in severe conditions than a synth oil MAY help engine wear. BUT, if you change your oil every 3K than there is no BIG difference in engine life. The LONG LIFE OILS have more additives and additional additives to increase seal life.

I have 3 years of data on 5,000 Hp pumps here at work with royal purple vs regular lubes. There is only a slight difference in rpm, amps,vibration, when using the synth after 3 years. but the synth cost 4 times the regular price! Not a bargin!
