10w30 will work fine. The benefit is improved mpg and better cold starts than 15w40. My owners manual says you can use 10w30 from 0-100 degrees. It was actually developed for the trucking industry so I wouldn't worry about pulling loads.

My current fill is Delo 10w30 and so far, the hot oil pressure has been the same as 15w40...

If your not pulling a load at all ever I cant see a problem with 10w30. I run full synthetic esso 0w40 year round, pulling a load or empty.
Like I posted earlier, the 10w30 was developed for the trucking industry and we all know they "never pull a load"...

:rolleyes:
