Yeah, I think that Nissan 0W20 synthetic oil at 6 qts. for $22.99($3.83 qt.) is a decent price.
Sure, you can get other synthetic oils for le$$ after rebate but, those would be 5 qts(~ $2.50 qt.) and are obviously an even better deal.
My Altima owner's manual calls their oil, Nissan Ester 0W20. So, am I to assume that it is a true ESTER Group V motor oil? Hmmm!
