Full disclosure: I’m an independent AMSOIL dealer. I sell this stuff. I’m also paying the same increases you are, and every number below is sourced so you can check it yourself.
TL;DR: Motor oil prices are up an average of 24.2% since February 2026 — 87 of 97 products surveyed higher, none lower, some five-quart synthetics over 50%. The record oil company profits in the headlines are not the reason. Crude prices already came back down after the June ceasefire and your oil still got more expensive, because the actual problem is a physical shortage of Group III base oil. The practical response is fewer oil changes per year, not cheaper oil.
The Explanation Everyone’s Reaching For
You’ve seen the headlines. Eight major oil companies cleared roughly $93 billion combined in Q2 2026. ExxonMobil posted $14.5 billion. The conclusion writes itself: oil companies got greedy, so your oil costs more.
Those profit numbers are real. They’re just not the reason.
Pull up Exxon’s own Q2 filing and look at where the money came from. Total earnings: $14.525 billion. Upstream — pulling crude out of the ground — accounted for $7.927 billion of it. Specialty Products, the segment where lubricants and base oils actually live, earned $956 million. That’s under 7% of the total, and it’s the smallest segment they’ve got.
The windfall is in extraction, during a quarter when crude spiked past $100 a barrel. It is not in blending motor oil.
The Fact That Actually Settles It
Here’s the part nobody arguing about profits has accounted for.
Crude already came back down. Your oil didn’t.
Brent rose more than 50% during the conflict. Then the framework agreement came together in June, the Strait of Hormuz reopened, and the price collapsed — $17 a barrel over four trading sessions, landing at $78.24 by June 17. That put crude roughly 7% above where it sat before the war started.
If your oil bill were being driven by crude prices or by oil company margins, July should have been cheaper. Instead Group III base oil kept climbing right through July, and retail shelf prices went up with it.
That’s the tell. When the input that supposedly caused the problem goes away and the problem doesn’t, you were looking at the wrong input.
The second tell: this hit every brand at once. Pennzoil Ultra Platinum 0W-20 went from $26.50 to $39.97 — up 50.8%. Valvoline Extended Protection is up 24.2%. Across a matched-SKU survey of 97 products, 87 went up and not one came down. When the entire shelf moves together, that’s a raw material working through the system. A pricing decision looks like one company moving. This was all of them.
What’s Actually Broken
The problem is Group III base oil — the feedstock behind virtually every full synthetic sold in North America.
Missile and drone attacks hit refining and energy infrastructure across the Middle East, including Adnoc and Bapco. Premium base oil imports from Bahrain, Qatar and the UAE into Asia, Europe and the US fell from more than 185,000 metric tonnes in March to under 50,000 in May — roughly a 70% loss of supply in the exact grades high-performance synthetics are built from.
Prices did what prices do when 70% of supply disappears. Group III 4 cSt — the base stock in most 0W-20 and 5W-30 — went from around $3–4 per gallon in January to north of $13 by July. Spot availability is essentially gone and what’s left is being sold on allocation.
And it didn’t stop when the shooting did. On July 15, Penthol — the exclusive U.S. distributor of ADNOC’s Group III+ base oil — declared force majeure, citing transportation difficulties, unplanned outages, equipment failures and war-related events. Supply from ADNOC stopped. Penthol’s own language was that the duration is unknown.
The Independent Lubricant Manufacturers Association has an active supply crisis bulletin out over it. JobbersWorld, covering the market on July 29, stated plainly that pricing right now is driven by supply availability rather than day-to-day movements in crude.
This isn’t a price problem. It’s a molecules problem. Damaged plants and interrupted shipping don’t care what a barrel costs.
Where AMSOIL Landed
I’ll be straight about my own house, since I’m the one writing this.
AMSOIL issued a surcharge notice on April 8 citing raw material costs and the Middle East conflict, which at that point included the closure of the Strait of Hormuz. It worked out to roughly $1 per quart on synthetic motor oils and up to 16% on fuel additives and greases. Filters were exempt. They built it into the product price rather than tacking a fee onto checkout, and stated it as a temporary measure tied to raw material costs — to be adjusted or removed when supply stabilizes. I wrote more about why AMSOIL prices went up and why it isn’t just AMSOIL back in July.
You can decide for yourself whether that’s good enough. What I’d point out is that they said what happened, what it cost, which products weren’t affected, and under what conditions it comes back off. Not every brand did that.
What This Actually Means For You
Here’s where most of the advice going around is bad.
The instinct when oil gets expensive is to buy cheaper oil. That gets the math backwards, because you don’t buy oil by the quart. You buy it by the year.
Per-quart price went up. Fine. The number that determines what you actually spend is quarts per year, and that’s set by how many times you change it. A vehicle getting three or four changes a year buys three or four times the oil of one running a full synthetic on an extended interval.
AMSOIL Signature Series is rated up to 25,000 miles or one year in normal service. Most of my customers do one change a year instead of three or four. When the per-unit price climbs, that gap gets wider, not narrower. The more expensive oil gets, the more the interval matters.
The catch, and it’s a real one: this only works if the oil is right for the application and the interval is appropriate for how you actually drive. Severe service — towing, short trips, dusty conditions, a lot of idling — is a different interval than normal service. And I’m not going to tell you to run something your manufacturer doesn’t call for. Start with what the OEM specifies, then find the best product inside that spec.
Application matters. That’s not a slogan, it’s the entire difference between saving money and creating an expensive problem.
The Short Version
Prices are up because a war took roughly 70% of the premium base oil supply off the market and the damage outlasted the ceasefire — not because someone decided to squeeze you. Crude already came back down and it didn’t help. It’s hitting every brand on the shelf. Infrastructure damage suggests this doesn’t fully clear before the second half of 2027.
The lever you actually control is how often you’re buying oil at all.
If you want to know what your specific rig should be running and what interval makes sense for how you drive it, text SPEC to (651) 300-2010 and I’ll tell you straight — including if the answer is that what you’ve got is already fine.
