ABOUT AMSOIL
Powering Your Performance
AMSOIL was created to push what’s possible. For nearly 50 years, we have pursued that goal with a relentless passion and allowed it to inform every product, technology, and service we offer.
Full Service Dealer
At SPX SynTech, our journey with AMSOIL began when we started using it in our Harley-Davidson motorcycle. The performance boost, smoother ride, and engine protection we experienced immediately stood out. Impressed by the superior quality, we expanded AMSOIL's use to all our vehicles—from trucks to daily drivers—and noticed consistent reliability and efficiency across the board. The results were undeniable, and our confidence in AMSOIL only grew stronger. We were so impressed with the brand's commitment to performance and innovation that we decided to take the next step and become independent AMSOIL dealers, sharing these benefits with others who value quality.
