Hi there I too have a zd30 (2010 Mod) in a 2007 patrol (auto) the motor has only 30,000 Ks on it, But I cant keep fuel in it ? It runs great but at 5 Ks/Lt ,(14 mpg ) driven real quietly , It costs a lot to go any where , I took the MAF sensor out it seems to be new , Any clues what check next PLEASE ?
