Word on the street is that Castrol has reformulated its Syntec Blend (synthetic blend) motor oil to meet Dexos specifications. If true, this would mark the first instance of a branded motor oil meeting GM’s stringent specs without resorting to a full-synthetic product. Initial reports are that the new product will not significantly differ in price from current Syntec Blend products, which would be great news for lube operators trying hard to meet GM standards while encountering significant resistance from customers not willing to pay for a full synthetic oil change.
We’ve also heard that Shell’s Pennzoil and Quaker State brands are set to launch their own synthetic-blend Dexos products, which would be even more good news for lube operators.
UPDATE: As you might notice from the comments section, Valvoline, too, has a synthetic-blend product that meets Dexos standards. Even better!
