There are pros and cons on driving with a full tank or less than 1.2 tank.
Full tank
- Ensures your fuel tank will not rust
- Your fuel pump has an easier job due to the pressure from the fuel
- Heavier car which translates to a little higher fuel consumption (neg).
1/2 tank or less
- Lighter car since more economical
- Fuel tank may rust, but this is not an issue if you drive daily
- Fuel pump works harder
correct me if i am wrong, but are you talking about a carburetor now?
buddy, fuel tanks now are made of PLASTIC, and fuel pump works at the same rate NO matter what.
and NO, fuller tank doesn't mean higher pressure.
dude, come back to 2010 man, it aint 1980 anymore.
