Hello.
I am asking because I been lurking on here, reading about the sulfate ash, NOACK, calcium, and phosphorous etc.. But there no mention of the numbers for Mobil 1 EP and Pennzoil Platinum.
Reason why I didn't include Pennzoil Ultra because I can't get at Walmart for cheap.
As for specs, which oil, Mobil 1 EP vs PP, would be better for GDI engines?
Not looking to make an oil catch can either.
