The engine redesign in 2002 makes it mandatory for EXPERT testing of any used V8 [even V6] prior to purchase.
Many of the engines suffer from worn/weak/bad ring tension and extra oil consumption.
Failure by previous owners to constantly mantain FULL OIL can lead to even more severe damage that is not recoverable.
RUNNING low ONCE can allow overheats and head gasket damage and WARPED HEADS.If it is winthin 6 years [to the day] or 69,999.9 miles and you can prove with written documentation that every oil change was less than 180 days Nissan will usually replace engine.
Do you have all the documentation?
