Mobil 1 Question

[scottiemac]

I was in Walmart looking for oil and I found they had 5W40 Mobil 1 but it said on the label that it was for turbocharged diesel engines.

Is this the same as the 5W40 that is on the approved Porsche list?

Thoughts and comments appreciated.

My understanding is it will work fine.

Thanks. Appreciate the help.

You might want to compare the data sheets in the attached zip file from Mobil's website (downloaded May 2008).

You will see that a number of key parameters (total base number, phosphorous (as ZDPP I believe), viscosities) are very similar. I can't say for sure, but someone mentioned that the diesel formulation has significantly more detergents, which could be problematic if your engine is dirty, dislodging all kinds of stuff after the initial switch.

Just out of curiosity. Why are you considering an oil that is not specifically formulated for gasoline engine use? I presume that availability of suitable oils should not be a problem and pricing will not be very far apart either.
