Hello Everyone, I am a newbie with an 2004 C4S. I've been trying to read up on the different types of oils used in 996's. I've read so many different views on what to use ( M1 0w-40, Castrol 5w-40, Motul 5w-40, M1 15w-50, M1 Delvac 5w-40 etc.) I have always said that the "Proof is in the Pudding". Who has the highest milage 996 with original engine and what kind of oil are you using?

 

porsche 996 3,4 1999 96000miles,Elf 5W40 is super.

I used castrol and damaged the engine

 

Sold my car with 157,000 miles. Only used Mobil1 0-40

 

Interesting about castrol. There are some on the web that said castrol witj the higher zinc content would actually be better. Thank you for sharing sir.

 

157k? Did you do the ims upgrade or was it the original? Im impressed. Thank you.

 

Some people have said that using a thicker viscosity oil is better for the ims. I believe that even LN Engineering was referring to 5w-40.

 

Yes, LN does like the 5W-40. Plus, they specifically mention to use the oils with higher concentrations of Zinc and Phos. Sounds like a few have had exceptional luck with the Mobil too / the proof is there. I'm curious if the high mileage porsche had a new IMS bearing too. If not, wow...good job.

 

97,000 on a 2000 cab. mobil 1, not sure on viscosity as it only gets changed every 15,000 when i get it serviced at the local indy.

 

Did you do your IMS on your car? That is great...keep up the good work. At those miles I'd 1/2 th miles between your changes at least. Just my .02 as you're doing great on the miles.

 

Where's the popcorn icon when you need it.

 

117k Mobil 1 0w-40..... No issues

 

My perception from all my reading is that Mobil 1 0-40 is FAR FROM IDEAL for our cars. Seems like the opposite. It has some good and actual results. Anecdotal?? I was actually a little worried because I used Mobil 1 when I did my IMS Guardian because I had 10 qts in my shop. Now, I won't worry (as much). Ha

 

Original engine with no IMS upgrade. No problems using Mobil1 0-40. at least for me.

 

I'm very impressed with Mr. Joel Pirela's results with M1 0w-40!!!! Keep it coming folks.

 

I am impressed. Thank u sir.
