Engine oil Castrol or PENNZOIL

I have a 2010 Jetta TDI cup edition with the CJAA engine and the factory spec listed in the manual is 5W-40… On top of that the oil cap alone has Castrol on it\nSo Castrol 5W-40…. End of story…. I apologize if I sound condescending as I do not mean to and also recognize you may have purchased your vehicle second hand and it may have not come with a manual… But if the top of your 710 aka oil cap says Castrol on it and you truly have a CJAA engine then I guarantee you that Castrol 5W-40 is the proper oil regardless of location or climate Ps…. Anyone who claims to use or recommend anything else has also probably had massive engine problems or engine repairs an question why they had those issues Follow factory spec and maintenance recommendations…. I’m pushing 280k on my CJAA engine without a single issue

Done 2 oil changes so far and car has not used a drop of oil and I drive it pretty hard.

I’ve used Castrol and Castrol High Mileage on my Mk6. At just over 143K miles, I’ve had no engine issues at all.

Been running Castrol in my VWs for 20 years. Never had any issues.

Castrol euro has been good to me for the last 120k miles.

Great oil, I go with the Ultra Platinum. So far it's been the absolute quietest (based on subjective valvetrain sound) and smoothest driving oil I ever used. I tried OEM, Valvoline, Castrol. Nothing was as smooth as the Pennzoil even after a few thousand miles. I still change it every 5k for peace of mind.

I swear by penz ultra platinum/euro platinum in my cars. Really good anti wear additive package in that stuff.

em troca do óleo eu sempre usei 5w30 da Castrol, ate agora com 227.000kms com o mesmo motor só misturei 2 oub3 vezes no deposito da gasolina. Sempre foi o meu carro e nunca me deixou na estrada

I have used Castrol and it seems fine.

I know I was using penzoil back when I had a 90 325i, locked my engine up solid, mechanic said it had too much paraffin so yeah it matters personally I only use Mobil 1 synthetics
