Gas here in Canada is now $1.07Cdn ($0.92US) per litre, diesel is $0.92Cdn/litre. MIght as well explore the concept.
Last summer, drove around Western England (Exeter to Tintagel to Torquay) in a 2005 SAAB 95 Diesel, same tankage as here (48litres) but
1000 kilometers (600 miles to the tank) as opposed to the 500 kilometers if I'm lucky with the V40.
Same size engine, FOUR adults in the SAAB.
