well...if i were to throw my 2 cents into the pot
I would have to agree with Ashman.
There's been ALOT of discussion about synthetic vs. non-synthetic oil. From what iI have been told and from what I have read in other sources, the quality of the oil is not as important as the frequency and the regularity of the oil changes. If you change your oil religiously every 3000 km, you don't need to pay the extra for synthetic oil.
If you're onre of those people that leaves the oil change for about 5,000km or more, then you may want to consider it. Although I don't know what good it will do at THAT interval *L*
