Having taken possession of my Kluger Grande 2WD back in Feb 2009 I have consistently done 14.5L - 15L / 100KM on regular unleaded - which is quite high compared to Toyota's 11L/100KM rating. I then discovered this website and have read up on some of the things people have tried to get their fuel consumption down. I have since switched from regular unleaded to V-POWER and have seen NO affect. I will next try BP 95 and/or 98 and replacing the engine oil with Mobil 1 0W-40 oil as "Rice racing" had done / suggested. Does anyone strongly believe that replacing the oil will bring down the fuel consumption significantly - I ask because I am reluctant to do it becuase of the complexity in doing it yourself and quite costly to get the dealer to do it. Also, FYI my wife is the one who has been driving and clocking 14.5L - 15L / 100KM - mostly city driving. Can anyone provide suggestions as to how I can improve fuel consumption. Thanks in advance.
