Hey guys , I recently got a 14’ is250 with 94k. It says use full synthetic 0W-20. How many quartz would I need & what brand would you guys use in particular thank you!

 

6.5 quarts

Any brand will do. I use Pennzoil.

 

Use whatever is cheapest. I go back and forth between Amazon 0-20 and Castrol 0-20. And this is coming from an oil snob. Apparently Walmart Supertech is just as good too. They fluctuate between $16 and $22 for 5 quarts. But the V6 it seems makes it to where you need to buy two of them then have some left over for the next change.
