Should I put E5 fuel in my car if I'm not going to use it for six weeks?
Should I add E5 fuel to my 2022 Suzuki Vitara if I'm not going to use it for maybe a month or six weeks? I read somewhere that E5 is more stable but I read somewhere else that it attracts water and will corrode the fuel system.

It is correct that ethanol is hygroscopic in that it attracts water, but as E5 has a lower ethanol content compared to E10 it has a lower propensity to do so. However, as your vehicle is only three years old it is designed to work with fuels containing ethanol, so we would not expect this to cause you any issues.
