Back to the TSB EG018-06: So, if your oil filler cap or manual requests 5W-20 as a recommended grade, you can use ILSCA-GF4 instead of the API SL/GF3 in the manual. I cant see any other way to interpret this TSB.

Yeah, my cap says 5w-30 and I don't know why I'd ever want to switch to 5w-20 eventho' the TSB says it's okay. The 5w-30 is in the owner's manual and appears to be the superior grade, at least where Pennzoil Platinum is concerned:

5w-30 (ACEA A5/B5)
5w-20 (ACEA A1/B1) ...maybe because 5w-20 has a higher "piss" content?
