Oil: Penzoil Platinum Euro L 5W30
Engine: Ford 3.7 liter V6 Duratec
Miles: 4942
Vehicle: 2019 Lincoln MKT Livery (similar engine in Ford Taurus and Explorer)
I have come to the conclusion the type of oil placed in this particular engine will probably not yield significant changes. The most significant conclusion is using 5W40 in this engine does make it quieter and more refined but thats it!
The Penzoil Euro L is a thick 5W30...maybe it should be labeled as a 5W40.
The absolute best results came from a batch of Amsoil Signature 5W30 but when compared to the other oils there wasnt a significant difference.
Lastly, my testing should not be taken as it doesnt matter what oil you use with an engine. Its just that it doesnt seem to make much difference with this engine...Ford 3.7 liter Duratec V6. I did find there was a difference with the Ecoboost engine line, but with this engine not much different.
I will no longer be testing oil frequently with this engine. I will test on every 3rd oil change.
