Shell contest vs Petronas Contest

today will be the beginning of Petronas contest and it will end on 28th March 2010

i am a loyal user of Petronas before the Shell contest start on 30th November 2009

now...i am prepare to switch totally to Shell as it have saved me a lot in term of money and more mileage

Petronas are seen desperate by Shell promotion and they just have to improve a 'LOT' in their Primax95 for me to switch to them again
