AMSOIL Signature Series Synthetic Motor Oil, our highest level oil, offering motorists maximum protection and performance. Designed for 25,000 miles or 1 year, AMSOIL Signature Series goes above and beyond in meeting and exceeding the highest performance standards. AMSOIL Signature Series Synthetic Oil is offered in 7 Viscosities, Click Here, to see if we have the Viscosity you are looking for.  

Depending on your car, the kind of driver you are, and what type of commute you have, the drain interval chosen by the motorist can vary. If you are in severe service or operate an older vehicle the drain interval can be shortened to 12,500 miles. However, this is still a lot of miles. Do what is best for you. I have put this oil to the test in the 10W-30 viscosity and 5W-30 viscosity in my Jeep Grand Cherokee and have been very impressed with the performance. The most impressive is that the oil doesn't burn off like some other main stream brand synthetic oils I have used. It is recommended to-always check fluid levels regularly and top-off when necessary.

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.
