I cant find Mobil 1 15W50 anywhere other than 10$ single qt bottles. I need 10 Qts for a porsche boxter. The only (reasonably priced) 15w50 was napa synthetic at < $6 per qt. Problem is my porsche guy will only use mobil 1. No walmart around me has it. Neither advance or autozone
Is 15W50 going the way of PU???

Not sure what's going on with M1 15w-50 availability, but isn't M1 0w-40 a better oil for the Boxster anyway?
I usually get it at NAPA.
Sounds like it's time to switch to something more readily available.
+1 on checking if the M1 0w40 is compatible, especially since its not being used on the Autobahn if its in Florida.
5w40 is a better choice or even 0w40.

Every WM here has a full stock of the 5 quart 15W50 jugs. I wish WM would carry Syntec 5W50. See if you can do a site to store order.

Syntec 5w-50 has been my first go to 50weight.

I thought it took 0w40, which should be easier to find, along with meeting Porsche's A40 standard required for the Boxster, which Napa/Synpower 15w50 doesn't meet, and neither does M1 15w50.
Valvoline does have Synpower MST 5w40(but unfortunately no Napa-branded equivalent) which is also approved against A40.

I like this one much better than the M1. Looks better on paper too.

Enter you zip and see if any of the stores near you carry it.

I just looked at my local walmart - they had M1 15w-50 jugs in stock. But again, it is the M1 0w-40 that carries the official Porsche approval, and not the 15w-50.
If you're looking for 15w-50 and can't find it I suggest either a 15w40 hdeo or a 20w-50 motorcycle oil.
M1 15w-50 on paper is seriously neutered compared to their v-twin oil,and the viscosity difference is on the front end which shouldn't make much difference unless you're driving it in the winter.
And the v-twin stuff is more shear resistant too,however I'd make a decision based on where and how it's driven,taking into account max oil temps and pressures and the minimums of both then go from there.
If m1 0w-40 is allowed I'd use it without question but I'd also consider ambient temps at start up and if it's warm enough I'd seriously consider rotella 15w40 conventional. It's cheap and can take some serious heat and abuse. It also retains its viscosity well which is important if the engine is of the air cooled variety.
And it's cheap enough that you're never trying to extend any intervals trying to get your money's worth out of it.
Just a thought.

If you really need some Mobil 1 15w50 PM , I have about a case I don't need anymore and will sell it cheap!
Why a 15w50?? It calls for 5w40. And can obviously run 0w40...

Probably because someone (likely another car forum) has the car's owner convinced that M1 15W-50 is the "best" oil for his engine and running anything else will destroy it.
