That is the same oil as Pennzoil Platinum Euro 5w-40 in the American market.... check out the doc posted in post #4..... with the only difference that the names have never been changed
Has anyone been able to compare the PDS (product data sheet) between the older and newer recommendations? I'm curious what the changes were. I'll post on bobistheoilguy.com and see what they say....
Anyway, I think we're overthinking it. The foaming I had was caused by overfilling a tad. I removed close to a quart, let the engine run, and kept checking level as it warmed up. Engine cold, first pic with low level; engine hot around 150F second pic. Image Unavailable, Please Login Image Unavailable, Please Login
My dealer told me that the recommended Pennzoil is not available. Instead they use Liqui Moly Top Tec 4110 5W-40 from Germany.
I notice the Shell Ferrari spec oil always has a BMW LL-01 approval. I would believe that would be one additional guide beyond the 5w-40 viscosity specification when selecting something other than the OEM recommendation. One of the specs of LL-01 is a minimum HTHS of 3.5 or greater (high temperature/high sheer). Most LL-01 oils will be between 3.6 and 3.8.
I have a 612 and just got her back from a Major service at the dealer (SF Grand Est) in Mulhouse…they are using q8 Excel 5w-40 for oil changes now.
I’ve tried quite a few different oils in my Testarossa and now F430. I found that pennzoil 5-w40, with the horse, foamed a lot in both cars. Especially in the F430 as the previous owner had really overfilled it. Oil laying everywhere in the intake track. That’s another story about differed maintenance.☹️ I use Mobil 1. 0w40 with the FS on the label. Both cars have substantially less mechanical noise at startup and when idling fully up to operating temperature. To me less noise means less metal to metal contact. The oil also appears clean , clear on the dipstick between annual changes. I find this to be a good source https://540ratblog.wordpress.com/2013/06/20/motor-oil-wear-test-ranking/ no affiliation , it’s a very long read Barry
I am staying away from Mobil 1 since I saw that bad Blackstone analysis ... a lot of metal wear. ...startup noise is probably due to being thinner and getting into the nuts and bolts earlier/easier which is very good... . It does not say anything about how well it does under sustained stress, like track days Also, I read up on bobistheoilguy; good oils supposed to have detergents in them; which means they will clean the engine, so they will become black or dark colored soon in life. My Redline oil is dark like honey now after only 800 miles, which I am happy with. It means it's cleaning the engine bits. I think we're overthinking it, any of the current modern oils should be good as long as change intervals are not too long... (and you don't use Mobil 1 - running for cover now)
