Poor gas Mileage
Even after I put some 285/75/16 tires on my 2000 Z71 I swear I was getting 15-16 mpg. That had to be 7+ years ago. Recently I've been getting 12 mpg even after I changed the fuel filter, spark plugs & wires, and air filter. No SES light, adaptation values: short term B1=1.56, short term B2=.78...- ChunHimself
