Hi All, How easy is it to chnage the oil on a 225tt? Bearing in mind I have never attempted anythig like this before! Is there aguide anywhere or any advice greatly appreciated. Are either of these oil's ok to use Mobil 1 (0-40) or Castrol SLX. And where can i get it for the best price for the change (assume i need 5 Ltr's) please? Also mileage is just under 70k at the moment and I belive the cambelt and tensioners will need doing soon (2001 on a Y). What's a guide price to get this done at an independent specialist? many thanks for any help!
