Engine oil PENNZOIL or OEM Mazda

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.

Remember that the rotary engine burns oil by design and does not particularly like eating synthetics. Expect to use old fashioned dino juice and change your oil every 3000 miles.

I’m using Pennzoil Euro 5W40.

Although this is exact replacent, mazda OE still uses Mazda branded GF-5 which is exactly the same oil but branded Mazda....

Love these high molly low viscosity oils. Absolutely the best out there

Pennzoil Ultra Platinum has been doing well in my UOAs.

I've switched to Pennzoil Platinum Pure Plus. It's cheap, it's easy to find, and it's got those nice lubricating additives that our hot-running FA20 motors and Garrett turbos like.

FA20s show regular positive results with Pennzoil Platinum PurePlus.

I run Pennzoil Platinum in mine (same engine) which is another popular oil. 5w-30 btw.
