For most people their driving habits will never need an oil as good as red line,some applications can benefit though such as in racing applications and any application where you need the best possible protection.
Rotella is good oil however its a group 3 base stock and has been watered down to qualify for dpf exhaust systems.
Rotella is more stout than most of us will ever need as well however I think red line is the top shelf of oils. Superior base stocks,extremely stout additive package. It's as good as oil gets,and more than 99% of engines will ever need.
And it's expensive. 22 bucks a quart here. I can get a jug of pp or qsud at Walmart on sale for roughly the same price as a single quart of red line.
But if cost wasn't an issue I would use red line products exclusively.
I can't help you on the Amsoil hdd. I have no experience with it.
Thank you for clarifying that to me. I suppose, aside from just wanting a good oil....I am experimenting.
My wife has OEM Nissan conventional oil and is coming up on an oil change. Her engine is noisy. The winter is making the noise worse. I suppose I am wanting to try an oil that is considered the best in quieting engines to see how dramatic of a difference it would make.
Of course, a noisy valvetrain is a mechanical issue but high quality oils have been known to improve such things. Using a slightly thicker oil is known to improve this also.
So, knowing what I've learned from this thread, I'm wondering if Redline has the potential to make her engine quieter and smoother than Rotella T6. LeakySeals said from his experience Rotella T6 was quieter than RedLine. But I wonder if that is engine dependent or not.
On paper Redline looks like complete overkill and should blow the doors off anything. I have a PhD in overkill so that's why its so appealing to me.
Maybe Rotella T6 with Lubro-Moly MO2?!?!?!
