For those that buy synthetic oil for their vehicles, usually consider pricing in their purchases along with quality. AMSOIL has a full line of premium synthetic lubricants. With the Preferred Customer program you can save on all your purchases. I have had several readers of BITOG contact me about prices and when I explain about the PC prices they are very suprised and will generally purchase products more readily for other applications because of the performance/costs benifites. Check out the product line. If you have been considering changing over to a premium quality synthetic but were afraid of the percieved high costs, we may just be able to help you. Contact any one of the AMSOIL sponsors on the board here. One thing to consider is if you have an older vehicle with lots of miles/KM and it's on it's last legs....this isn't a miracle in a bottle. It won't prolong the life of that vehicle. Mechanically sound vehicles is what we work with.
