Engine oil PENNZOIL or Mannol

Use Penzoil Ultra Plat. Can probably stretch it to 5k miles with no issues.

I switched to 5w30 Pennzoil Ultra Platinum a long time ago on my 2.0T. 140k miles and running strong. FK8 CTR Turbo added around 133k, too. FBO PRL mods!

As an additional word of advice. Do not use Mannol 5w30 C3 oil when doing oil changes. Use a high quality oil- castrol,shells, millers.. these cars are very sensitive to oil

I run Pennzoil or Motul depending on if I grab filters locally (Walmart for Pennz) or buy an oil change kit online (most use Motul). I would have no quarrels running Toyota's oil (Mobil 1), Subaru's Oil (Idemitsu), Valvoline, or any of the other reputable brands in my car

have run penzz plat 5-30 for the entire life of the car almost, recently switched to the high mileage version as im pushing almost 150k miles on it.

i use pennzoil plat every 3k seems to be fine for the past 57k miles

I go every 5k using Pennzoil Platinum 5w-30, though it's just a stock engine/tune and more than half are highway miles

The engine itself runs great with the 48K I put on it in the past 2.5 years with biannual oil changes (Pennzoil Ultra Platinum). Averaging 27 MPGs on 91 Octane hwy miles, 24-25 mpg in the city.

Mannol is a legit brand. Although not as critically acclaimed like Liquimoly, Rowe, Fuchs, Addinol, or Ravenol. Probably on par with Voltronic.

I know I was using penzoil back when I had a 90 325i, locked my engine up solid, mechanic said it had too much paraffin so yeah it matters personally I only use Mobil 1 synthetics
