Seat Ibiza 6J 1.4 16V Oil

Audi also have "Castrol" moulded into the oil fill cover. It used to be that all Seats had a Repsol sticker under the bonnet.

I'd rather see the oil going a bit blackish rather than it staying golden as that is an indication that the oil has enough detergent in it, staying golden means that it is not picking up or scrubbing up the engine's inner surfaces.

Mine was darkened gold colour when I dropped it out after a good 6 months of thrashing, I thought golden was the sign of no internal problems in the engine.

Some might think that I'm sticking my neck out here, but, as most if not all modern engines are essentially "low friction" engines, that means that blow-passed gases will get into the crankcase areas and they will mess up the engine internals with carbon, acid etc, if you use low detergent oils then the oils will stay clean and the engine's internals get dirtier and dirtier quickly, if on the other hand, like quality engine oils, they are loaded up with detergents, the build up of stuff on the engine internals will be a lot slower and the oil will get black quicker. Some of this "loaded with detergent" is due to same oils being used on DERV engines, but they do keep petrol engines cleaner longer.

The only time that a petrol engine will not make its oil black will be when it is newish.

Actually a lot of synthetic oils don't tend to start life golden "old school" oil colour, it will depend on what modifiers have been added as to what the colour starts off like.
