Engine oil Castrol or VALVOLINE

No issues at 150k on my 6. I do not worry but do run pea type injector cleaner every 3-5k and use quality oil that helps prevent off gas issues like Mobil 1 and Valvoline

Walmart sells the Castrol full synthetic eurocar recommended by Audi.

Just to let everyone know, VW/Audi recently dumped Castrol and they now roll with Mobil 1.

I run Castrol Edge in mine, the spec exceeds API SN PLUS/SP and ILSAC GF-6, coupled with a genuine hyundai filter

I use Valvoline Restore & Protect, which claims to clean your engine and reduce friction/wear more than any other oil

I use Valvoline Extended Protection Full Synthetic 5W-30.

Very good on engines and your turbo especially (i have a 2014 st3)

I use Castrol as it’s the OEM product and is cheap if you buy direct from Ford.

My more modern VW runs Castrol EDGE OE 5W-40 full synthetic. That's what my VW dealer in Utah fills cars with.

I have a 2011 Escape Hybrid 2.5L with about 175,000 kms. I run Valvoline Advanced 0W-20 full synthetic as recommended by my mechanic. I've found it much better on fuel economy in colder weather than the 5W-20 for multi-seasonal use, especially in colder weather regions (I live in BC, Canada).

Former BMW dealer employees have confirmed that the overpriced BMW oil is literally castrol edge.
