NEWBIE
 

I'm new here just wanted to say I love the web site and I have used alot of your tips and tricks 04 sv650 in the avatar.

Nice to meet you,

semi

Semi for me too - I think that those that have tried fully synthetic have had few problems.

semi is my choice but at the mo its synthetic

semi as per the SV manual

Semi as per manual & dealer (as it's under warranty).

semi as well

I used to work for a Suzuki dealer and if ever we phoned their technical people for advice on a transmission glitch (Dragging clutch and noisy gear selection being favourite) their first question was always "Has the bike got fully synthetic oil in it?". If the answer was "Yes" their advice was always "Put something else in it" and putting something else (eg. semi-synth) in it always did the trick.
Also, the Castrol rep once told me that the last thing anyone should put in a new engine is fully-synthetic because it is so efficient it will prevent the engine running-in. As Castrol obviously make more profit from their most expensive products, any advice not to buy it must be worth heeding.

whatever the dealer puts in it ere :roll:

Semi too.Better to put a lower spec oil in as long as it is of adequate quality and spend the money you save on changing it more often IMHO.
