What's your climate like? I'm in Brisbane, Australia and we've had a very hot and humid summer. After seeing the results my tuner has recommended going up to HPR10 10w -50.

This is what so conflicting about so many opinions and UOA reports, even to the ones deemed "normal" something sinister was lurking. I think I'm just going to put this to bed and enjoy the car, it's running flawlessly so I may very well be worrying about nothing.

The previous owner was using Castrol Edge 5w 30 and I switched to Penrite 5w 40 as soon as I got it. Yeah it's a Japanese import with a full service history.

Yes, first in this car and first UOA. No cooler or adapter change recently either.

74000kms.

All duly noted. It spools fine and no funky noises but I'll keep all that in mind. I'll continue with the testing on a 6 month basis and hopefully things improve.

And yes it's tuned conservatively with no knocking that's apparent.

Yeah there's not much I can do in the meantime. It'll be a stressful 6 months till the next change.

I'm hoping someone could shed some light on this being my first UOA on my 2007 Subaru Forester STi with 74000kms on it. There was 4000kms on this particular interval and it also had 2 separate dyno sessions. I'm hoping this isn't the beginning of the end. Cheers
