2003 Yamaha R6 synthetic oil or no?

I have a 2003 Yamaha R6 and this is my first bike. I’m wanting to go ahead and change the oil because I’m not sure when the last owner did but didn’t know if it mattered if I used synthetic oil or if I just needed to use regular oil.

It's fine to use. I'd go with 10w40. It's what I always put in my 2006.

I've always used Mobil1 4T 10-40w, but that is up to you. Depending on your climate, you might want different viscosity oil.

mobil 1 isn't actually synthetic unfortunately. that's why it's only $10 and $5 over priced. it's only petroleum that has undergone extra refining. yeah it's technically better than regular oil but it's still not a real synthetic oil and definitely lacks all of the benefits of true synthetics. a true synthetic oil is group 4 and group 5 oils. typically the bottle is typically labeled as 100% synthetic if it's real synthetic. real synthetic oil is polyol ester and polyalphaolefin.

anyway, if you want brands what are true synthetic, Yamalube, Motul, Maxima racing, MPT, redline, Bel-Ray, silkolene, amsoil. and many others. just look on the label. if you see ester on it, it's a good, real synthetic oil.
I'm currently running MPT this summer. tests results are not in but it sounds good on paper. although it seems they didn't fill the bottles completely and I need a 5th bottle to fill a 4qt crankcase.

Re: 2003 Yamaha R6 synthetic oil or no?

I wouldnt put too much stock in "ester" vs mineral for normal operating conditions.
You can change mineral oil pretty frequently vs the ester ones and not sacrifice wear or service life especially on a factory built engine.
Also I will state that the so called synthetic Rotella in the blue bottle... is good enough to finish inside the top 10 at the Daytona 200.

Now if you embark on a superbike type engine build...then yes the esters are dramatically better but require frequent service intervals.
