We Tested 87, 91 & 93 Octane In The Same Subaru — One Clear Winner!

We tested 87, 91, and 93 octane fuel in the same Subaru. Same car. Same driver. Same routes. Same conditions. Three different fuels over three months of controlled testing, and there was one clear winner. Not the fuel Subaru marketing suggests. Not the fuel your dealer recommends. Not necessarily the most expensive option. The actual winner surprised us. And the results have real financial implications for every Subaru owner—whether you drive a naturally aspirated Crosstrek or a turbocharged WRX. We didn't just measure fuel economy. We measured everything. Power output. Engine knock events. Fuel economy. Real-world cost per mile. Long-term engine health indicators. After three months and over 9,000 miles of testing, we have definitive answers. In this video, I'm revealing every result, every data point, and the exact fuel recommendation for every Subaru model currently on the road. Whether you've been running premium thinking you're protecting your engine, or running regular to save money, you need to see these results before your next fill-up. ► SUBSCRIBE:    / @everythingsubaru   #SubaruMaintenance #SubaruMechanic #SubaruCare #SubaruOwners Ready to get the most out of your Subaru?
