[Skunkworks] <OT>Survey on engine oil vs fuel consumption

Hey members, I have a theory that engine oil (brand and viscosity) affects the sort of fuel consumption one gets, therefore, to get some numbers behind this theory, I have created a simple, 5 question survey. http://goo.gl/forms/GYCuXy2VPt I hereby kindly request you all to take a minute or two to answer those questions. Results are and will be freely accessible. Thanks!
