Engine oil Castrol or OEM Audi

I've been using Castrol GTX High Mileage for almost 10 years in my 2009. I've always done 10,000 mile changes and I've got 298,000 miles on it. Blackstone tests on my 10,000 mile oil say it should be good for another 2000 miles.

Always used Castrol in my cars when I\u2019ve had the choice and never had a problem.

On my previous car, a VW Golf 7 2.0 TDI I used to change the oil (Castrol 5W30 Long Life) every 12000km.

Had an 02 explorer with the 4.0 that had 286,000 and still running like a champ when I sold it. It was on its second transmission and everything in the vehicle was falling apart but that motor never once had an issue. Regular maintenance and oil changes every 10 to 15k using Castrol GTX fully synthetic

I put some Castrol 0w20, no issues.

Castrol mangnetec gave me good performance but in city conditions it gave inconsistent fuel economies for me and under normal cruising speed 80-90 it performed really good. But for me it felt like reaching higher speeds above 100 felt slower compared to shell. Initial pick up of my car felt higher with this oil.

I have a 2012 civic with 220k miles still use Castrol 0w-20. I've been using it since 500 miles switched to the high mileage stuff around 100k

Castrol Edge is usually cheaper than Mobil 1 and will be as good.

Can use 5w30 or 5w40.

0w40 or 5w40 will give you slightly better engine protection if you drive at high rpms more often.

I wouldn't use anything cheaper or different than those two really. You don't need more expensive oils than those either.

Al producătorului, Mobil1 sau Ravenol în general. E ok și Castrol doar că în experiența mea se înnegrește mai repede și trebuie schimbat mai repede pentru o funcționare lină a motorului.

It\u2019ll be okay. Subaru engines are robust and that mix rate won\u2019t increase the viscosity enough to affect the oil flow rate out to the cams.\nPardon my skepticism regarding Castrol oils though. Haven\u2019t been a fan of them since the GTX days. The additives they\u2019d chuck in their generically sourced base oils glazed bores and gummed lifters.\nCost many a machine shop like ours a fortune in comeback work.
