Best Engine oil for Ford Explorer

Had an 02 explorer with the 4.0 that had 286,000 and still running like a champ when I sold it. It was on its second transmission and everything in the vehicle was falling apart but that motor never once had an issue. Regular maintenance and oil changes every 10 to 15k using Castrol GTX fully synthetic

I have a 2007 Explorer with 161,000 miles on it. Just recently switched from Castrol to Valvoline Restore and Protect. I'm not sure why I haven't heard of it sooner, but from what I've heard, it's really good at removing sludge and varnish that forms in high mileage engines.

Petronas is a pure virgin oil.

Great for UAE road and climate.

I personally use Petronas oil or petromin oil.

Great performance and good mileage getting.
