Engine oil Mobil or Castrol

I use 5w-20 full synthetic from Mobil One. I change it every 5k miles, no more, and never have any issues with it.

Preferred Castrol edge 0w-20 during the warranty period and 5w-30 after the warranty period. The engine is quieter with 5w-30.

The ss will have Castrol that they use for big bikes it’s better than prolube and Motul 7100 in my experience.

I prefer Mobil 1 oil, some people will swear by the or that brand. I just wouldn’t buy store brand stuff myself.

I just use Castrol magnatec 10w40 here in the Netherlands in my m20.

I am running 0W-30 (already passed my powertrain warranty). Engine sounds quieter and better (ie less trashy).

Mobil Super 5w30 Sintético; pelo pouco que vi pelo buraco da tampa de óleo, **a p a r e n t e m e n t e** o motor do meu carro quase não tem verniz encrostado

The closest I found was Castrol? Long life 507 which was £40 for 5L from Amazon, but I had to buy the stuff direct from VW as was pushed for time for my oil change (with a friend).

Currently using Castrol Edge 5w-40 fully synthetic, previously was using Estremo Heatpro 5w-40 FS, differences is so minimal to the point where you just neglect and forget about it....

Smoothness the same, silky smooth.

Car feels slightly like just slightly lighter on pickup with Castrol.

I hated the castrol, I could tell the engine was louder with it compared to Pennzoil.
