I have used Penrite HPR-5 in my Xtrail since new and it has been great. It is reasonably priced at $50 a container and the car now has 100k on the clock and no problems to report.

Had a micra that I serviced on the cheap every 10 000 km. Used a Gulf Westen oil @ $12 for 4 litres on sale at Auto one and had no problems. The bigger issue was with the oil filters. Have tried cheap ones and these are not worth it. The micra would suffer from low oil pressure, sucking in the sides of the filters etc. When using nissan or rycos I have never had a problem.

So any reputable oil at the right viscosity should be fine, just spend some $$$ on a good filter. Not 10 for $15.00 on ebay like I did.
