5W30 is what is recommended but if you look in the owners manual you will find info on other oils for very extreme high and low temps. RedLine meets all requirements Nissan calls for for an oil it even has the ester additive that is highly recommended to be used in these engines so no it will not void your warranty. Good choice in oil its what me and a lot of other members have been using for years.
