I use Mobil 1. change it every 5000km... im sure changing the
oil makes a difference.. it's like the oil tends to harden as
time goes by... it revs more freely... I change my oil filter with
this.. takes 15 minutes...
benm,
It's easy.. all u need is a jack.. a size 14 socket.. the tool to
remove the oil filter.. and a drip tray.. and u'r away...
