Official AMSOIL programPreferred Customer program
Buy at wholesale, not retail
The Preferred Customer program is AMSOIL's wholesale pricing membership for people who buy lubricants regularly rather than once. If you maintain a boat, a truck and a couple of small engines, the math is straightforward — the membership typically pays for itself on the first real order.

What you get
Membership benefits, as AMSOIL publishes them
Save up to 25% on every order
Wholesale pricing applies to the entire catalog, every time you order — not a one-time coupon and not a limited product list.
Free shipping over $100
Oil is heavy and shipping is a real cost. One combined seasonal order for the boat and the truck usually clears the threshold on its own.
$5 back per $100 spent
Earn a coupon for every hundred dollars you spend, applied to future orders.
Free renewal at $500
Spend five hundred dollars in a membership year and your renewal is complimentary, so the membership effectively becomes self-sustaining.
Birthday coupon
AMSOIL sends a coupon on your birthday. Small, but it is there.
Members-only promotions
Exclusive offers run throughout the year for Preferred Customers only.
How it works
Four steps, about five minutes
01
Register on AMSOIL.com
Use the link on this page so the account is associated with Gulf Synthetics USA. It takes a couple of minutes and you choose the $10 trial or the $20 annual term.
02
Prices drop immediately
Wholesale pricing is live on your account as soon as registration completes. You can place the first order in the same session.
03
AMSOIL ships direct to you
Orders are fulfilled and shipped by AMSOIL INC., not by a dealer's garage inventory. Warranty and returns run through AMSOIL directly.
04
Ask me anything, anytime
You still have a person to call. Product questions, application checks, drain intervals — 512-554-6817.
Which one am I?
Preferred Customer or Dealer?
Both get wholesale pricing. The difference is whether you want to resell and earn commissions, or simply buy for yourself at a better price.
Preferred Customer
You buy for your own boat, vehicles and equipment. No business obligations, no sales requirement, no reporting. Just wholesale pricing and free shipping thresholds. This is the right choice for most people who land on this page.
Independent Dealer
You want to sell AMSOIL — to marinas, shops, fleets or retail customers — and earn commissions on those sales. It is a business registration rather than a discount program.
