A friend is in the PowerSports rental business and is a Bombardier (CAMAM, SKIDOO) authorized rental dealer. He get dealer prices on parts and lubricants from CanAM, Skidoo etc. Well about 2 yrs ago that stopped as they jacked up his prices so high it made AMSOIL look like discount oil. So he became an AMSOIL dealer (to get the lowest prices) about 2 yrs ago and that's all he buys now, mostly by the drum, up to a doz a year, mostly 2 stroke but the fleet is moving to 4-stroke gradually. After a year of use he sells off the old rides and get all new, part of his deal with SkIdoo and CanAm that he rents current year models, approx. 50, snowmobiles, ATV/UTV and Jetski's. Not only has he saved a lot of $$ on oil, he told me last month he has not lost one engine since he switched to AMSOIL Interceptor. It was not uncommon to have a few engines go down on the snowmobiles as renters can push them to 100 mph on trails. The units get lots of miles. . That's more profits for the comp.
