My Nissan engines are tough on oil, therefore I have used synthetic lubricants for over 15 years. I have researched many different oils on my VQ35DE. Several years later and allot UOA’s the numbers surprised me. The run of the mill Castrol 5W30 GTX outperformed most of the synthetic lubricants. After my Mobil 0W40 stash is exhausted I will be buying the Castrol 6 gallon oil in the box. Doing the right thing needn’t cost $5+ a quart. Who would have thought that Castrol mineral oil would turn out better UOA's than Mobil Synthetic? I am now a Group 2 Convert.
Feedback would be greatly appreciated!
