AMSOIL Synthetic Oil and Lubricant Dealer

My name is Kevin Eyre, Independent AMSOIL Dealer, T-1 Certified since 2015. Graduating from the University of Arizona, in Agricultural Technology Management, with an emphasis in Turfgrass Management, gave me an interest in equipment maintenance and lubrication. The turfgrass industry is one that relies heavily on its machines, and if they are not properly maintained, repairs and downtime can be costly to turf managers. Looking back I was always intrigued with the maintenance and lubrication of all kinds of equipment, pondering over what brands of oil are the best, and with so many to choose from, I would commonly ask myself if there were performance benefits from one brand to the next. Growing up around heavy equipment, my family owning and operating a bus company, working on several golf courses, and owning a small delivery service, I quickly became to realize the importance of using high quality lubricants. Equipment downtime is the last thing you want in the middle of your busy season. Personally putting AMSOIL synthetic lubricants to the test has been very helpful in witnessing the benefits of AMSOIL products, to include cooler operating temperatures, burning less oil, and overall increased protection under extreme working conditions.
