I have new 07' CBR and have just got past break in period. Might be dumb question but should I switch to full synthetic oil or not......does it really make all that big of difference? and if it does, what?

 

It's personal preference... Some people will say full synthetic others are against it. Personally since its such a high performance engine i use full synthetic. In any case, whatever you decide to use stick with it. Dont run a full synthetic then change later on.

 

It doesn't make a lick of difference one way or another. You'll end up chainging the oil at 2500 miles anyway. Synthetic will just hold together better than convential. that's the only difference. any talk about smoother shifting operation is just bogus feedback. I went from GN4 to Amsoil MCF, stored it, switched back to GN4 and haven't felt a difference yet.

Also, you can switch back and forth between conventional and synthetic all you want. there is no rule on oil anymore.
