2008.5 MS3 GT
102,XXXmiles
No bolt ons (only mods; suspension, rmm.)

Dry: 175/174/174/170
Wet: 179/181/179/180

I was a happy, happy man today. Having the VVT and timing chain serviced, then tuning to head for 200K. Would love to keep this car for the long-haul. Always regretted selling my '03 SVT Focus, and I won't be making that same mistake again particularly since my motor seems solid.

Also, hello. I think this might be my first post.

2007 MS6 with 111K miles. Engine up to temp/ dry test.

My fairly new compression tester read:

Cyl 1: 180
Cyl 2: 180
Cyl 3: 180
Cyl 4: 180

Autozone rented shoddy compression tester read:

Cyl 1: 165
Cyl 2: 165
Cyl 3: 165
Cyl 4: 165

What would you believe? The autozone comp gauge or mine? Either way, I'm stoked.

Even if you believe both and compute an average, 172PSI across the board is an awesome number for this mileage.

So the usual question: what oil, how often?

Got the car July 2015 at 80K miles from original owner. Older family man that drove it for work and took great care of it. Clearly. I've never launched, drag raced (ok once against a cobra mustang F body and won) or beat on it.

I took it home and put in Rotella T6 5W-30. Changed with same every 3K-4K miles.

Saturday when I did the test I put in Penzoil Platinum Euro 5W-40.

My turbo seals are leaking into the intake and exhaust at the moment. Just bought a 70K mile K04 to replace it with. Can't afford the BNR S4/V2 with supporting mods right now.
