Reviews of Castrol engine oil

castrol 5w40 is what vw puts in the new passat. just did my 5k oil change the other day. i used a original vw oil filter also.

All oil changes on this car have been done with Castrol Syntec 10W30 Full Synthetic and an OEM Mazda Filter.

From what I can find, Castrol makes a 0W30 longlife oil which can be used in VW engines which have sensors which support the longlife service regime. According to this regime, oil change intervals can range from 9,000 miles or 12 months to as long as 30,000 miles or 24 months - IF the sensors will allow such an extended interval.

In the early years only VW dealers carry Castrol Syntec 5w-40 oil which is where I am always getting from.

I used some castrol 5w50 at my last race. Oil temps saw like 270F.

As much as I love to use Mobil One, I am going to stick with Castrol because VW dealership won't give me any credit for the Castrol in exchange for the Mobil one.

I had to top off once and used Castrol Syntec, which is about $3.50 where I live.

My favorite is simply Castrol drive hard. I run it in all my engines except the VR.

The oil used by VW is made by Castrol. Of course, you can't buy it in any store.
