100,000 miles on a Victory V92C - Performance

"While it's the world's highest mileage for the cruisers since the first Victory V92C production model rolled off the assembly line on July 4, 1998, Werder is an old hand on a bike. He's been riding since he was 16, even traveling more than 10,000 miles by motorcycle on his honeymoon with his wife Christine."

Practice Sled Survives on AMSOIL - Racing

"...I've checked bearing, bushings, gears, chains and all internal engine parts. Other than a little scuffing on the intake side of the piston skirt, nothing wore, no extra play in bearings and everything was within tolerance. I credit this to AMSOIL lubricants. No other products have been used in this sled."

AMSOIL extended drain intervals means fewer oil changes, long term savings and convenience. Even if you drive only 12,000 miles per year, the cost for AMSOIL motor oil is less than you pay for petroleum oil now! And you still get better wear protection, lower engine temperatures, improved fuel efficiency and easier cold-weather starts. All of these benefits add up to reduced operating costs and longer engine life. Change your oil and filter today and in 12 months change the oil and filter again. That's it! What could be more convenient and good for your vehicle, too?
