I wouldnt say that you never have to do it again......it just changes your normal intervals. Like when Im due my first oil change in about 600 miles, I am switching to AMSOIL Pure Synthetic. It was $60 for oil and filter, but its guaranteed for 25,000 miles. Personally Im not gonna go that long on the first one......maybe 15,000 then cut the filter open to have a look inside my engine. And if all is well, I will go 25,000 the next time.
Synthetic lubricants are signigicantly more expensive, but they offer FAR BETTER wear protection on your critical engine and transmission parts. Any time you reduce friction and wear, you are opening that engine up to more power. If you change oil, transmission and rear end fluid to FULLY Synthetic, I wouldnt be at all suprised to see horsepower gains. Less Friction = MORE POWER.
One thing to note also. Oils have been altered significantly in recent years. Used to, oil companies put Zinc Additives in their oil to act as a high pressure lubricant. But the government has stepped in recently and forced oil companies to cut back on Zinc. With this cut back, using conventional oils arent as good for your vehicle as they used to be. This can be very noticeable on engines with flat tappet cams and lifters. Many times they are damaged in the break in process simply because of the oil. However, fully synthetic oils such as AMSOIL are exempt from the above government standard because they are rated for higher mileages. I forgot the exact mileage amount, but if it is rated for a certain mileage, companies are still allowed to use the Zinc additives for wear protection. Another oil that is exempt would be Diesel oil, such as Shell Rotella. That is why synthetics such as AMSOIL are rated for gasoline or diesel engines.
I hope this all makes sense. If any of you are interested here is the website that I purchase my AMSOIL products from
