Premium unleaded or E10 for Prius? in Prius Club Posted February 1, 2020 On 4/16/2015 at 11:26 AM, Hybrid freak said: I use E10 -95 from 7-11 and E10 -94 from Speedway . E 10 from United is also good. Do not use Wollies because I shop at the German Supermarket. Get 3.7 L/100 over a full tank on my PriusC and just a shade under 4L/100 on my old Prius. Had the HV Battery on the old Prius serviced. Made a big difference Hi Jurgen, at what stage did the Prius's (Prii?) batteries need servicing or replacing (which?) and how much did it cost?
