Fuel Saving Tips
Most vehicle handbooks will list the different engine oil viscosity which are safe to use in your engine at a given temperature. Pay attention to the climate you experience and use the least viscose oil as this will have less friction in your engine. I was using 5w30 as per the handbook in my Toyota, someone suggested I should be using 10w40. I tried this and my MPG went down so I switched back to 5w30. Make sure the grade is appropriate for your engine and climate and only use the least viscose oil that is specified for your engine and climate. Mine is 5w30.
