I dislike Pennzoil so - noyt for me. personally after killing ALL my engines to early in the past 5 years with this crap US spec oils, I would only run the real stuff imported from Europe: Total(ELF), Motul, Fuchs, Pentosin, Haven't tried Amsoil yet. May give the ATM blue cap Amsoil a try, Better to give my $$ to the good ole USofA other than the EU.

Since you have this thing against what you consider to be fakes, funny that you'd pick blue cap Amsoil...you're meaning the XL series? It's group III and ACEA A1/B1 nothing too special about that.

No, Ist, its the 10W-30 PAO base meat-and-potatoes product. The dealer doesnt sell amsoil anymore so I just put some Valvoline grpIII/IV Synpower 10W-30 in for the meantime. I hear the Amsoil doesnt have API SM/SL certification.
On the grpIII - I just havent had any formula work well for me YET. And I jumped on that ISO syn bandwagon with the Chevron Process when it first came out. Good luck with the P-Platinum its had really good UOAs as has V-Synpower. It's just Mobil-1 that has high iron and Cu consistently and failes to meet its API certs down the road. Funny that Mobil Clean 5000 is a good sleeper Dino oil.

Amsoil does have API certification. Like I said, it's only on their XL series, which is API on every XL grade, and XL is ACEA A1/B1, and like I also said, it's group III. I posted the link from their site where it states they went group III to keep it competitive, pricewise, so they could offer API approved oil to the market. I think I did see a blue topped 10w30, and yes, it wasn't certified, and not group III, good for 25K, guessing A4/B4.

Ahh gotcha on the XL. I wasnt looking at the grpiii so I didnt read into it much. Here is a question I'm not fully clear on: Does Toyota warranty require API cert or is this just a recommendation/guidance? I'm assuming the emission warranty requires the use of low saps so you have to stay with an SL/SM rating. But certification IDK ....

I thought it was pretty much common knowledge for the last 15 years or so that the oil had to be API approved, here in the U.S. ...and that's sort of been the problem at most of the forums I've been at over the last few years, a lot of people want to run the better oils, but they don't always have the API approval stamp on the front label.
