Engine oil PENNZOIL or IDEMITSU

Idemitsu is the only premix and engine oil I’ll use ... you can order it for a good price from TREx performance out of NJ and he will ship

Pennzoil Ultra Platinum every 3k miles religiously.

The project farm video convinced me to use Pennzoil Ultra Platinum. It’s about 98% of the performance of Amsoil for much less money.

From what I've read online, Pennzoil Platinum 5w30 is a solid option that you can find at most retailers.

The oil was Idemitsu Synthetic 0W-20 with 12.5k miles on it. Once again, trace metals and flashpoint were within normal range. I also ordered a TBN to measure the amount of additive left and that showed there was still plenty of active additive remaining.

In terms of oiling, get a sohn adapter so your apex seals aren't being lubricated with crankcase oil, and instead are injected with rotary-specific oil, like idemitsu.

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.

I’m using Pennzoil Euro 5W40.
