Every 5,000 miles with conventional oil and every 8,000 miles with synthetic.
If you use conventional oil then change the oil/filter every 5,000 miles. If you use Synthetic then change it every 7,000 miles. However if you do lots of stop and start driving of trips less than 5 miles then change at 4,000 Conventional and 6,000 Synthetic.
If you drive under normal conditions, I recommend changing conventional oil/filter every 5,000 miles. Blend every 6,500 miles. Full Synthetic every 8,000 miles.
Around 5,000 miles with conventional oil and 7,500 with synthetic.
Every 5,000 miles with conventional oil, and every 8,000 with synthetic.
if you drive normally, mostly highway, and not in dusty conditions then I would recommend you change it every 7,000 miles. If you drive mostly city then every 5,000 miles. I do not recommend you use a synthetic blend. Either use conventional oil or 100% synthetic. With 100% synthetic you can go 8,000 miles.
Change the oil/filter every 5,000 miles if you use conventional oil, and every 8,000 miles if you use synthetic.
5W30 (for warmer climates you can use 10W30 or even 10W40) conventional oil or synthetic blend (Nissan does not recommend full synthetic). Make sure it is API Certified SM or SN. Change conventional oil every 3750 miles, synthetic blend every 5000 miles. New oil filter with every oil change.
Oil last forever but oil does get dirty. Synthetic oil like conventional oil does get dirty. You can extend your oil changes slightly if you synthetic oil but no more than two or 3000 miles.
If you drive normally and use conventional oil then my recommendation is to change the oil/filter every 5,000 miles. If you use synthetic then change it every 8,000 miles. If you drive in very dusty conditions then change it more often. If you drive mostly highway miles then move to 6,000 miles conventional and 10,000 miles synthetic. Or you can follow the manufactures recommendation listed in your owner's manual which is always best.
What does your owners manual say? I personally change the oil/filter every 5,000 miles if you use conventional oil or every 7,000 miles if you use synthetic. But it is best to follow the recommendation in your owners manual.
Castrol Syntec. I recommend when switching to synthetics from conventional, that you run a synthetic blend for 6,000 miles (two oil changes) then change to full synthetics. If you have no experience with changing oils (especially changing from conventional to synthetics) I do not recommend you attempt this.
