Engine oil PENNZOIL or Eneos

Eneos 5w-30 full synth for my 06 WRX. It has a high zinc content.

I have exclusively used Eneos 0w-20 in this car - the non-Sustina version. This past oil change, I started using Eneos Racing Street 0w-20 as they're phasing out the OG 0w-20.

Both have worked very similarly for me. No issues with anything other than E85 dilution when I'm running it.

I run Eneos 0w-20. Lots of people love Mobil1, if only because it is often on sale at WallyWorld.

Even though Amsoil produced the lowest wear numbers I'm using ultra platinum since I find that is what my car runs best on, engine is quieter than with amsoil or Mobil and velvety smooth.

In our 2003 1.8T Passat, we use; Pennzoil Platinum Full Synthetic High Mileage 5w-30. Changed every 4000 miles. Because we made the change early, we have not had and engine oil sludge problem. The Passat now has 205k miles.

Pennzoil Ultra Platinum is a crowd favorite and what I've been running in mine.

Eneos 5w-20 in my 2008 2.3 liter Mazda3. It's a Japanese-branded synthetic oil that you can get from Napa Auto. I've found that with Eneos, my Mz3 stops consuming any oil (in both my 2007 and 2008 2.3's).

I’m using Pennzoil Euro 5W40.

Eneos 0-20.

Pennzoil Ultra Platinum has been doing well in my UOAs.
