Review on 🔧 Mobil 1 Advanced 15W-50 Full Synthetic Motor Oil - 5 Quart for Optimal Engine Performance by Joel Gardner

Although this is a so called European formula I started using it on my 2014 Infiniti Q60S and older Nissan 350Z which had around 130,000 miles on the odometer. The oil pressure is higher when the engine is fully warmed up and also slightly lower than 10W30 when the engine is cold. The engine also seems to be quieter. I don't really know the life limits of an oil as I don't subscribe to long drain intervals of 7500 miles or more. Z says to switch to 3600 and Infiniti says no more than 5,000. 3,000 to 3.5,000 km and use Mobil 1 filters. Let's face it, no matter what oil you use, it still contains combustion byproducts that turn into both sludge and soot over long intervals. The Nissan V6 is unforgiving of mud or varnish build up and using this oil as I have done in a 350Z at 130k miles when I removed the valve covers to replace the gaskets everything underneath was a lustrous silver without the usual brown color of the paint. I find this oil stays cleaner for me than other brands of oil when I change it. In addition, the engines are quieter.
