The 508 spec gets you better mpg and less dirty emissions. Gotta look at the bottle carefully. Mobil ESPX2 0w20 has that spec.

Pros: better mpg, less emissions

Vehicle: Volkswagen Jetta

I use PUP 0w20 in mine. Lots of tests and UOA show that Pennzoil Ultra Platinum is the best non-boutique oil you can buy. But honestly any top shelf oil will work. 5k km intervals are more important than brand with a turbo engine.

Pros: best non-boutique oil

Vehicle: Toyota

Mileage: 5000 km
