Or do they use the regular 0W-40 formulation? I've read conflicting information and instead of just taking the dealer's word for it, I prefer to "trust but verify." Does anybody know for sure?
There's not indeed. But worse, there's no 'European Formula' anymore. Mobil changed the formulation, but the aholes left the name, only adding a sneaky miniature 'FS' nearby. According to BITOG, it's crap. That's why I wouldn't go 10K miles on that. I'm probably going to change it to something better next time... but plan to do some research if Mobil1 0/40 Extended Performance is any better. That one only costs like $3 more per jug than the regular one. I wouldn't extend the interval, but would like to get rid of the 'rapid ticking' typical of Porsche flat-6s, if possible.I do not believe there is a non-European formula for 0-40 weight.
No 981 comes with extra oil. If yours did, it was either the previous owner (if used), or dealer did it as a tacked-on extra (Suncoast sells those Porsche bags. I have one). Porsche recommends Mobil1, but it's just a marketing scheme. Each dealer does the same crap, as noted above, and mostly buy from bulk (55-gal drums with no labels), which I don't trust, for several reasons. Much better to buy a jug or bottles yourself (so you know exactly what's going in there), and let it drain the 2+ hours that it takes to go from stream to rapid dripping.what is brand in the oil reserve bottle in your frunk? My Cayman came with Mobil 1 0w-40 Euro Formula
Hey, I paid cash too (6 figures), and no free oil. Ha ha. That's the 'crappy' oil, by the way (look for the 'FS'). Oh, and I put mine inside one of the cubbies until the first oil change, when I took it out, due to no oil consumption. That way, it didn't take space in the already limited frunk.no extra charge from my dealer, maybe because I paid cash
I doubt they use Mobil 1 solely. But they probably do use one listed on the Porsche Tech Bulletin that meets their A40 standard. I used to buy Mobil1 from the dealer parts dept while picking up a filter. He would try to be very competitive.Or do they use the regular 0W-40 formulation?
