Engine oil Castrol or OEM Volkswagen

Previous comments about mobil 1 are right it’s best for reliability - castrol are seen as high performance oils

5W-30 Castrol Edge. FPRS uses it and has had very few failures on stock motor cars. I was also running it in my GR86, and Blackstone came back perfect on that car.

Castrol in my daily driver. The daily would have a slight ticking when warming up with other brands, not with Castrol, so I been using it for over 100k with no issues.

Have a look on Amazon they do some good deals on oil, I normally stick it in my basket and wait for it to drop.

My old car was Castrol 5w30 Magnatec, £28.50 for 4l on Amazon £43.99 from euro.

Using Castrol EDGE Euro 5W-40 after watching a EN owner on YouTube suggested it. Car runs great in this 110 plus days in Texas

I did 100k on Castrol gtx in an f4i plus tens of thousands on other bikes using the same oil. I buy it in bulk and it goes in the whole fleet.

In the rare occasions I get it from there, I use Castrol or Mobil One 5W-30 or 40.

Walmart carries jugs of Castrol Edge SPT 0w40 A3/B4 for much less than quarts at AutoZone

Run it in my R, wife's GTI, and even ran it in a WRX I used to have. It's good oil, the analyses I've sent in over the years don't lie!

Castrol Power 1 isn't a bad oil, but I'd say not the best either. I have only used LiquiMoly as an alternative, so far and I rate is better than the Castrol but it did cost almost 2x as much too.

My Mk4 Golf is at 146000. And I've religiously changed oil and filter every 4000. One time I let this synthetic oil go for 9000 miles, it caused pre-ignition and destroyed 2 sparkplugs, needed a tow, and a expensive sparkplug replace at VW.
