I can change the convencional motor oil for sinteric motor oil in many next service

Sure, should pose Zero problems, just use the manufacturer recommended grade of oil.

whats the percentage of synthetic oil in this oil?

We never divulge amounts of components in our products but we would not call a product a synthetic blend without it having a performance benefit as compared to our conventional product.

Generally i use highmileage 5w-30 for my nissan sentra 2007 which has 200k miles, shall i use highmileage 10w-40 now?

Look what Nissan says on weight to use and stick with it. It is designed to use the weight as for the clearances on you motor. Once you used the high mileage continue to use it. The high mileage has stuff in the oil to expand some of the seal and gaskets in your motor. Now if you go back the seals may shrink back and start to leak. Go to youtube and look for the video on different filters and oils. ie fram. I had a someone tell me to get the fram off my 92 ford 5.0 mustang and watching the video on filter I could see why. Oil is important but especially the filter.

Can you use it in a 212 predator

Contact Predator to see if that oil is compatible with your boat.
