Mobil 1 0W-20

@Sportsguy83 - If you can find it, Pennzoil Ultra is supposedly the best stuff out there right now. Of the ones you've posted, I'd search a bit on BITOG and pick the one with the lowest NOACK value.

Off the top of my head, of the ones you listed, I *think* people like the M1 Extended Performance.

Cheers

I've only found Platinum off the shelf, might try other stores to see for Ultra.

Thanks!!

Platinum is still good stuff. The ultra is supposed to be even better. From what I've read most pick PP over M1 standard, M1EP~=PP, and PU better than both.

Sorry, I missed this. I would top it up with some Mobil1 0W-30 Racing oil if you need to add any.

I probably would have picked the Mobil1 ESP 5W-30 based on the HTHS. It has a low TBN though so I wouldn't go any further than 5k miles on it. I would definitely do a uoa (with TBN) on the EP though. It might be fine for your conditions, but anything Resource Conserving is typically know to shear down a grade in Subaru turbos.

Mobil1 5W-30 High Mileage would have been my second pick since it has a higher HTHS than the RC Mobil1 oils or even Mobil1 10W-30 High Mileage as it meets Euro ACEA A3 specs (higher HTHS than M1 5W-30 HM).

Euro Castrol 0W-30 is probably a good bet as well. Yes, the Pennzoil oils are good and PU 5W-30 has been shown to stay in grade in stock, mainly highway driven WRX's over several consecutive uoa's. The PUP 10W-30 has a very low NOACK volatility at 5.7% (lower than Red Line 10W-30). http://www.pennzoil.com/wp-content/u...F-5-en-TDS.pdf

Edit: Scratch the 5k recommendation on M1 5W-30 ESP. Change at 3k running E85 regardless of what oil you run!

Thank you sir!! I am definitely going with a 3K change interval because of E85. I appreciate your thoughts!

Sorry to disagree but the air cooled Porsche motors going 200k miles are running a high Zink oil like Brad Penn. M1 is notorious for leaking in motors 1989 and older.


And for the record, I have been, and continue to be, a Porsche air cooled owner since 1971.

Okay so I see a lot of info and discussion but is this going to blow my engine or not. I have been using it for like 10k miles. Minimal track use all seems fine, so is this a bad oil or what?

Hi. Without reading through 100+ threads above, I will tell you that my friend with a 2013 has tracked a few times (Thunderhill and Laguna Seca) with Toyota's 0w20 oil. He dailys it and a lot of miles. No issues so far.

I personally use Mobil1 0w30 since it's mostly a track car, and not driven much on the streets - heavier oil weight has killed my MPG. I got the car this past Halloween, and only tagged on 6500 miles.

I've done 7-8 track days and some in 100*F heat. Motor's still good. I will suggest 100 octane when you're on the track, just so you don't pull timing.

Feel free to make your own judgement as to if your motor will blow or not.

Hope this helps in anyway. Good luck.
