Question Reguarding Synthetic Motor Oil

[Honda4trax250x]

I have never ran synthetic before, but the truck I just bought has been running on synthetic since day one. I gotta change my oil tomorrow and was wondering, with synthetic do I drain and replace all oil as usual or just replace what was in the filter with a quart?

Thanks.

replace it all and a new filter:p

can you go back to regular after synthetic? im about to get a HC2 in my 450r but am running synthetic now and I dont think i can break it in with synethic. can I switch back to regular honda oil for a few hours during the break in?

I've heard that you can switch back, as long as you are not going back and forth all the time. Break in with regular oil and not synthetic.

Thats just what I've been told, I've never had to break in though, and I run synthetic in my 400ex but regular in the 4x4.

i would stay with synthetic. i like it better.
