Engine oil Castrol or PENNZOIL

Liqui-Moly is also good, as are Amsoil and Pennzoil Ultra Platinum. I never had good luck with Mobil 1.

I might switch to liquimoly like a lot of ppl do but I’ve always stuck with the Castrol edge 5w-40, changing around 5k

I been using castrol 5w40 since I got the car new at 82 miles no issues. Sent my oil samples to blackstone for analysis and oil is really good even at 10k.

That's what the dealer and I use. Castrol 5W40

A few years ago Castrol decided to dye all their Magnatec oils green... it was pretty dark green as well.

I used to use German Castrol 0w20 in my Volvo and it was green too.

I use 10w40 full synthetic oil, and only the best quality stuff. Valvoline, Castrol, Pennsoil, Mobil1, Idemitsu end the like. Before my rebuild, I was using Idemitsu Rotary blend but switched to Castrol GTX. The GTX semi synthetic blend had a slightly lower oil temp and lasted longer per oil change than the Idemitsu, indicating that it was lubricating better.

I think you will find out Castrol EDGE® Euro Car 5W-40 A3/B4 Full Synthetic is a better all around oil then and oil I’ve owned Volkswagen all my life and that’s all I’ve ever run in my vehicles never had a problem and if you want to run the 10,000 miles between oil changes this oil will handle it

I keep a running supply of pennzoil ultra platinum 5w30 around as 4 of our vehicles use it. I start to worry when I have less than 10 quarts.

Pennzoil because it runs about 20°F colder for me.
