NHTSA widens GM L87 engine probe as 0W-40 recall fix runs into tight Group III base-oil supply
More than a fix for GM owners, the L87 recall is now a supply problem for anyone who sells motor oil. NHTSA is examining hundreds of engine failures tied to GM's 2025 recall remedy, and that remedy leans on 0W-40 at a moment when Group III base oil is already under cost and supply pressure, according to Thomas F. Glenn of Petroleum Trends International, writing in JobbersWorld.
The 0W-40 squeeze
Work through what the remedy actually asks for. GM's fix pushes affected trucks and SUVs toward a 0W-40 full-synthetic spec, and full synthetics in that grade lean hard on Group III base stock. That base stock was tight before NHTSA opened a wider probe. Add a recall population in the hundreds of thousands and you pull extra 0W-40 demand into a market that can't easily add barrels.
For a jobber moving branded and private-label lubes, that could mean thinner allocation on premium synthetics and firmer pricing on the exact grade dealers and quick-lubes will be asking for. Watch your major supplier's fill rates on 0W-40 first. If the probe widens the recall or changes the spec, the demand pull changes with it.
Hormuz and the crude you buy
The other pressure on rack pricing is coming through crude. India's crude import bill has climbed since the Iran war choked Middle Eastern supply, and the mechanics matter for US buyers because they move the same benchmarks. Freight rates on the key Ras Tanura route out of Saudi Arabia have quadrupled, and insurance on a single Strait of Hormuz voyage is at record highs.
That is landed cost, not just flat price. When it costs four times as much to move a Saudi cargo and the insurance on it jumps, the delivered barrel gets more expensive on top of a higher benchmark. US refiners don't lift much Gulf crude directly, but the benchmark move and the freight signal feed into what shows up at the rack here. Crude could ease if the strait stays open and freight settles.
Tanzania LNG
Equinor says the $42-billion Tanzania LNG project looks more attractive now that the Middle East conflict has crippled LNG flows through Hormuz. "You don't want to wait too long to put new LNG volumes on the market, so maybe now is a good time to get on with it," Equinor's Philippe Mathieu said Tuesday. The project has sat mostly stalled this decade, with Equinor and Shell still negotiating with Tanzania. It is years from moving any molecules and changes nothing for a US marketer this quarter.
What to watch
Whether NHTSA widens the L87 recall and holds the 0W-40 spec, how fast your supplier's synthetic allocation tightens, and whether Hormuz freight and insurance start to ease.
