Would recomend using a 15 - 40 or 15 - 50 semi synthetic rather than a 10 - 40 fully synthetic. Using a 10 grade oil is for tuned engines & will need replacing at far shorter intervals than a 15-40.
Also a semi synthetic oil is far kinder to your clutch than a full synthetic, you can get clutch slip on full synthetic but you will not get it on semi- synthetic oil.

The other point being price, one is a lot cheaper than the other, your engine will not bennefit from the over priced fully synthetic, so buying the semi synthetic will leave you with more in your pocket to spend on other things, your pocket, your choice.
