Engine oil Castrol or PETRONAS

Petronas Syntium 5w 30 on a mercedes and audi a6. No complaints at all, and good price

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’m definitely going to keep running Castrol Edge 0W-30 Synthetic European Formula. 10/10. It’s on the thicker 0W-30 side of things, so it really is somewhat of a 0W-35, it hits the spot when it comes to engine lubrication and protection when the engine is either cold or warmed up.

I've been using the original castrol 10-60 oil and then more recently the BMW M TwinPower 10-60 oil for the last 10 years on my e46 M3.

I was running Castrol 0w30 European formula in my 07 323i and the car ticked a lot and made noises I’ve never heard it make previously when running 5w30. So recently I swapped to castrol 5w40 European formula and the car is whisper quite even on cold starts. It just sounds so much healthier.

I'm using Castrol GTX 20W50 because it's the only 20W50 that I can easily find locally. I tried Rotella 15W40 but I found that it gave somewhat low oil pressure on my old engine.
