I bought a new 2016 Rogue three weeks ago. I've put 900 miles on it already. I'll do an oil and filter change at 1500-2000 miles. The recommended oil is 0W-20 at 5000 mile intervals but the manual also states 5W-30 conventional may be used and the warranty remains in effect. What I am wondering about is the shortened interval. I had a 2004 Altima with this same 2.5L 4 cyl that recommended 7500 mile intervals with 5W-30 "mineral based oils". Now they recommend a synthetic with a shorter interval in the same motor. Are they finding out this motor is tough on oil or just on the lighter 0W-20 oil. Toyota went from 5000 mile intervals with 5W-20 to 10,000 mile intervals with 0W-20. Also the manual talks about choosing an oil based on outside temperatures. Very vague. Are they saying I can use anything between 0W-20 and 5W-30 including 5W-20 and 0W-30 and anything from full synthetic to blends to conventional? I asked the service rep and he said their $39.95 oil change and tire rotation special is with 5W-30 bulk conventional and that's about all he knew. What I'll do is use 0W-20 at 5000 mile intervals. Oh well, all opinions appreciated.
