Owner reviews for engine oil

Takumi "High Quality" 10w40 full synth, I live in Australia so reasonably hot summers and winters only ever around 10C coldest. Oil pressures spot on for the spec around 72psi at 3000rpm

I run [Liqui Moly Leichtlauf 5w40] in my car. Even though it's a 2015, it has a motor out of a 2019.

Ran Rotella T6 5w-40 in my stage 2+ (and beaten to hell) WRX right up to 120k miles when I sold it.

It's perfectly fine for the WRX, and it's what I use in mine, as well as its two previous owners. My car's maintenance records include two reports from Blackstone Labs detailing their examination of the Rotella T6 5W-40 oil and according to those the engine has worn very well on that oil

I personally swapped from 5w-30 in my OBXT to T6 5w-40 and have noticed a decrease in oil consumption (newish engine with 28k so that also helps).

For Motul you want xcess not X-clean. X-clean is only for things with direct injection. I would do xcess or t6, ether work in 5w-40. I do both of them with my stage 2.6 IAG block as they recommend. Mostly Motul, but the last change I did was t6 since I could not get motul locally or in a reasonable amount of time.

I’ve heard a lot of people and shops use motul.

I use and recommend Liqui Moly 5w40 leichtlauf. It's LL01 approved and is really good quality.

I use Castrol GTX 20W-50, same as what the manual calls for. I know the oils changed since then but the previous owner didn't care for the car properly so I feel like the detergents are necessary.

I run Valvoline VR-1 20w50 in my '74. It is straight Dino oil but it has a higher amount of zinc in it which solid lifter cars like ours love.
