Engine oil VALVOLINE or PENNZOIL

5W-30 Valvoline SynPower (full synthetic) and Mahle filter since I picked this car up at 89k in '11. Just cleared 175k last week.

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 think what helped as much is the valvoline oil. Valvoline really agrees with my motor. Not sure why I have trouble with some of the other blends, but it's really quiet with the ashland add-pack.

Valvoline VR1 non synthetic. It is one of the ZDDP oils. Reasonably priced and the Z seems to like it.

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

[Valvoline SynPower](http://www.valvoline.com/products/brands/synpower/full-synthetic-motor-oil/5) is what I have run since I purchased my 2012 Subaru Legacy.

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.
