Prior to 2016 Nissan recommended 5w-30 for the VK56VD 5.6l V8 used in Nissan's and Infinity's. In 2018 Nissan changed the recommended viscosity to 0w-20SN for all VK56VD 5.6l V8's. I just purchased a new Titan XD with this engine that will be a long term truck for me. The use case of this engine in the Titan XD is different than say in the Armada - as it's my work truck that will see towing and heavy pay-load duties, compared to the use of it in the family SUV. Since this engine is direct injected (possible deposits?) and may generally be tough on oil (a lot of gears and it's camshafts are driven by two chains, one for each head plus the timing chain that transmits the rotational movement from crankshaft to the both intake and exhaust camshafts) I was wondering what folks thoughts would be on the best brand and formula of an API certified (the truck has a 5 year /100k mile warranty) oil to use ?
