Engine oil PENNZOIL or Motorex

Pennzoil Ultra Platinum has been doing well in my UOAs.

Motorex 60:1 piston and rings go 180 hours with out issue, could go longer but i change it every winter, powervalve has yet to need to be seriously cleaned in 3 pistons.

I went with the motorex recommended oil. Worked great.

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.

I use Castrol or Pennzoil most of the time (N/A engine or I'd use Rotella) haven't had any issues with it.

I have been driving for upwards of 50 years and have always had good luck with Pennzoil products. Pennzoil makes a 5W-40 full synthetic Platinum Euro which meets the VW 502 spec and has gotten good reviews from GTI owners.

I'm running Pennzoil Ultra Euro L 5w30. It's a low saps oil that's vw 504/507 approved. However, because of the high sulphur in US fuels, you can't run this oil longer than 5k miles. A low saps/low volatility oil will greatly reduce intake valve deposits proven by lubrizol.

I use pennzoil euro spec, I only go through about a quart between 5k oil changes.
