There is alot that can go wrong by letting a vehicle sit for along time.
1. Fuel turns to varnish and gums up everything includeing the injectors. ( Drain and clean tank, drain fuel lines and change filter. Run a cleaner wiyh clean fuel through entire system. This also can cause varnish was out that has adhered to the lines. Hopefully it will flush trough.)
2. Oil will also varnish out and stick lifters and not open valves properly as well as stick valves open.
All these things lead to bad performance and economy. You should be getting 12 to 15 MPG.
