Alan Williams AMSOIL Dealer Tomball TX

Alan Williams — AMSOIL Dealer #1243776 Updated June 2026

20+ years as an authorized AMSOIL Direct Jobber in Tomball, TX. I've watched AMSOIL pricing across every tier since 2004 and break it down honestly here — including the April 2026 price adjustment and what it actually means for your wallet.

AMSOIL pricing confuses a lot of people because there isn't one single price — there are four different price tiers depending on how you buy. This guide breaks down every tier with real 2026 numbers, explains the April 2026 price increase, and shows you exactly how to get AMSOIL at the lowest possible price.

⚠ April 2026 Price Update: AMSOIL implemented a temporary surcharge effective April 8, 2026 due to industry-wide increases in base oil, additives, and packaging costs. Standard synthetic motor oils increased by approximately $1 per quart. This affects all brands — Mobil 1, Castrol, Pennzoil all raised prices simultaneously. The cost-per-mile advantage of AMSOIL's extended drain intervals remains unchanged.

AMSOIL vs Competitors — Price Per Quart (2026)

Here's how AMSOIL Preferred Customer pricing compares to leading synthetic oils at retail after the April 2026 industry-wide increases:

Oil Brand Price Per Quart Drain Interval Cost Per 1,000 Miles Verdict
Conventional 5W-30 ~$5.00 3,000–5,000 mi $2.50–$4.00 Expensive long-term
Mobil 1 5W-30 ~$11.00 7,500–10,000 mi $1.65–$2.20 Good value short-term
Mobil 1 Extended Performance ~$11.50 15,000 mi $1.15/1,000 mi Strong competitor
Pennzoil Platinum ~$10.50 7,500–10,000 mi $1.40–$2.10 Lower drain interval
AMSOIL Signature Series (PC Price) ~$9.75/qt 25,000 mi $0.59/1,000 mi Cheapest Lowest cost per mile
The key insight: AMSOIL costs more per quart but dramatically less per mile of protection. At 25,000 miles per change vs Mobil 1's 15,000 miles, you're paying $0.59 per 1,000 miles with AMSOIL vs $1.15 with Mobil 1 EP — AMSOIL is nearly half the cost per mile.

The April 2026 AMSOIL Price Increase — What You Need to Know

In April 2026, AMSOIL implemented a temporary surcharge across most of its product line. This was not an isolated AMSOIL decision — it is an industry-wide event affecting every lubricant manufacturer in North America.

The root causes were supply chain disruptions affecting lubricant raw materials — base oil prices increased significantly, additives were up at least 15%, and packaging costs rose sharply. Exxon Mobil, Castrol, Shell, and Chevron all announced similar increases simultaneously.

What changed in April 2026
  • Synthetic motor oils — surcharge of approximately $1 per quart in the US
  • Fuel additives and greases — percentage-based increases of up to 16%
  • The surcharge is built into the product price — no separate fee at checkout
  • All other major brands increased by the same amount or more
  • AMSOIL's cost-per-mile advantage is unchanged — the extended drain interval still makes it the most cost-effective option per mile driven

How to Get AMSOIL at the Lowest Price in 2026

The single most effective way to reduce your AMSOIL cost is to join as a Preferred Customer. Here's the math on whether it's worth it:

Preferred Customer payback calculation — 5W-30, 5-quart vehicle
  • Retail price for 5 quarts: ~$70.00
  • Preferred Customer price for 5 quarts: ~$52.50
  • Savings on first order: ~$17.50
  • Annual membership fee: $20.00
  • Net first-order cost: $2.50 more than retail — membership pays for itself on your second order
  • If you change oil once a year at 25,000 miles: saves $17.50/year after year one
  • If you have 2 vehicles: saves $35+/year
  • If you also buy filters, ATF, or other products: savings compound quickly
Bottom line: If you buy AMSOIL more than once a year, the Preferred Customer membership at $20/yr pays for itself immediately. For most drivers it saves $15–50+ per year depending on how many vehicles and products you buy.
Frequently asked questions — AMSOIL pricing
At retail, AMSOIL Signature Series costs approximately $13–14 per quart in 2026 after the April price adjustment. As a Preferred Customer (25% discount), the price drops to approximately $9.75–10.50 per quart depending on the size you buy. Buying a case (4 gallons) gets you the lowest per-quart price at around $9.14/qt as a Preferred Customer.
Yes — for almost everyone. At $20/yr, the membership pays for itself on your second AMSOIL order. On a single 5-quart oil change, Preferred Customer pricing saves approximately $17.50 vs retail. If you have two vehicles or buy any other AMSOIL products (filters, ATF, additives), savings add up quickly. The only case where it might not be worth it: if you only buy AMSOIL once every 2+ years.
AMSOIL implemented a temporary surcharge in April 2026 due to industry-wide supply chain disruptions affecting lubricant raw materials. Base oil prices increased significantly, additives were up at least 15%, and packaging costs rose sharply. Every major lubricant brand — Mobil 1, Castrol, Shell, Pennzoil — raised prices simultaneously by similar amounts. The increase was approximately $1 per quart for standard synthetic motor oils in the US.
Per quart, AMSOIL Preferred Customer pricing (~$9.75) is actually lower than Mobil 1 retail pricing (~$11–12) in 2026. Per mile of protection, AMSOIL is dramatically cheaper — at 25,000 miles per change vs Mobil 1 Extended Performance's 15,000 miles, AMSOIL costs approximately $0.59 per 1,000 miles vs $1.15 for Mobil 1 EP. Over 75,000 miles, AMSOIL Preferred Customers typically spend $90–100 less than Mobil 1 EP buyers on oil alone, not counting fewer filter changes.
The cheapest way to buy AMSOIL is directly through an authorized dealer as a Preferred Customer — this gives you 25% off retail on every order. AMSOIL is not sold at Walmart, AutoZone, or big-box retailers — it's distributed exclusively through authorized dealers to maintain quality control. Through Lube Oil Sales, you can join the Preferred Customer program at amsoil.com/offers/pc (Dealer #1243776) and immediately start saving 25% on every order.
Yes — buying a case (4 gallons / 16 quarts) gives you the lowest per-quart price as a Preferred Customer, approximately $9.14/qt vs $10.50/qt for single quarts. For fleet operators or households with multiple vehicles, buying cases makes the most economic sense. AMSOIL's 25,000-mile drain interval also means a case goes a long way — for a typical 5-quart vehicle, a case covers 3+ oil changes. Contact Alan at 225-441-6397 for fleet and bulk pricing.
