Are you AMSOIL?
No. High Desert Synthetics is an Independent AMSOIL Dealer, a locally owned business in Sisters, Oregon. We are not AMSOIL INC. and this is not an official AMSOIL website.
How do I find the right oil for my vehicle?
Use the AMSOIL Product Guide on our Shop page. Enter your year, make and model and it will list recommended products. You can also just call me and we'll look it up together.
How do I order?
Online orders are placed through the official AMSOIL online store using the links on this site, and your order is credited to High Desert Synthetics as your local dealer. If you're in Central Oregon, you can also call or text to check what I have in stock in Sisters.
Why don't you list prices on this site?
AMSOIL policy says only AMSOIL INC. may post AMSOIL product prices online. You'll find current pricing on AMSOIL.com, in the free AMSOIL catalog, or by asking me directly.
What is a Preferred Customer?
It's AMSOIL's membership program for regular users. Wholesale pricing is available only through registration as a Preferred Customer. See the current program details on AMSOIL.com.
Do you work with businesses?
Yes. Shops, fleets, farms, ranches and retailers can open commercial or retail accounts. See Save & Join or give me a call.
Can you help with classic or vintage vehicles?
That's one of my favorite things to talk about. I restore vintage cars, trucks and Jeeps myself. Call me with what you're working on.
