OHV Oil question
i've been running 10w-30 in my truck for a long time, and its always burnt up a little bit of oil here and there, just kinda happens with the high mileage. but on my last oil change, i put in 10w-40, just to change things up, and i havent had to add any more for 2,000 miles. i know the manual recommends 10w-30, especially with the heat and all, but the 10w-40 shouldnt hurt right? it doesnt seem to burn off as quick either. kinda a noob question, but couldnt find anything in the search.
