Engine oil Castrol or OEM Subaru

Fa20 DIT..Castrol edge Euro..0w 40 winter, 5w40 the rest..111k miles, stock block, E85, 400ish whp, drive like I stole it..I change it every 3k, 4k a few times in a pinch...I also run an IAG street AOS

5w-30 Castrol LongLife in mine in Europe. But often interchangeable, but always depending on what the manual says. Top thing though I’ve found after 120k miles in on a TSI is: keep it near top of dipstick to bypass chain and turbo issues (turbo especially relies on good oil supply). Listen for rattling chain and listen to turbo note, can often hear changes and usually due to lower oil level.

I had a 2009 VW Rabbit, and I'd often buy Castrol Syntec (full synthetic). I haven't seen this 'Euro Car' formula, but it says it's full synthetic, so I think it would be fine.

Castrol a good engine oil, albeit more expensive. Stopped using them when the price went up significantly

Had it on all my bikes great oil. Cheaper alternative will be Castrol power one ultimate.

En VW cuando surgió el problema de consumo de aceite en una partida de los 1.6 MSI (16V), primero habilitaron a que los clientes llevaran el aceite de su preferencia para los services y yo comencé a llevar el Castrol Edge 5W-40 Titanium FST, que sigo utilizando, salvo que el último service (no oficial), le pusieron el Castrol Edge 5W-40 sin el antifricción (bidón negro) y le agregue un Molikote antifricción, por la falta del antifricción en el aceite. Ya va por los 223.000 km sin consumo de aceite, ni pérdida de potencia.

Castrol if you just wanna drive it.

I just buy oil with the certs for my car. VW certs are prominently labeled on oils approved by them. I usually use Castrol or Mobil 1.

I use Castrol EDGE Fully synthetic oil in my 2013 Mazda 3 skyactiv. It does burn a little but I did not have any issues.

Stay away from the stuff that the dealer puts in, the Euro Car formula(5w-30 i believe) that Castrol makes is a Blend, meaning not fully synthetic and it shears and burns really quick.
