Building on the legacy of Castrol® Hypuron™ 15W-40, new Castrol Hypuron Advanced Formula 10W-30 takes extended-drain intervals to a whole-new level of up to 70,000 miles(*) . At the same time, it offers equivalent-or-better engine-wear protection, giving you the kind of performance that Hypuron is famous for. Because it’s a lower-viscosity oil, you can also count on Castrol Hypuron Advanced Formula 10W-30 to provide fuel economy that’s superior to traditional 15W-40 oils.
We call it “extreme” extended drain. And for good reason. While Castrol Hypuron 15W-40 offers impressive performance—often extending drain intervals to more than twice the OEM recommendation, up to 50,000 miles—Castrol Hypuron Advanced Formula 10W-30 goes even further. It can extend your drain intervals an additional 20,000 miles, all the way to 70,000 miles (*). That’s a 40% improvement! Always use Castrol Hypuron Advanced Formula 10W-30 in combination with an oil-analysis program like Castrol’s Labcheck Total Fluid Diagnostics Program.
