The authoritive voice of reason thank you!!
Do you agree that 5w-30 is not ideal for an older sti b3 1997? Or do you think it is scaremongering? Just interested to see your opinion.
That said - I fully appreciate all the opinions so far!!

Hi
Some on here will definitely disagree about me being the voice of reason.
Yes, 5w-30 is too thin for that. Generally, I would go for a 10w-40 in a standard/close to standard one, driven sensibly or a 10w-50 if it's heavily modified or tracked a lot. The 10w-50 isn't going to be a problem if it's not heavily modified, but perhaps go for a 10w-40 next time.
Cheers

For comparison
My modded 120k jdm engine ran at 1.5 bar at idle on a 10/40 oil when temp got to 95 or above , a bit low for my liking
Switched the a 10/50 and now runs at 2 bar at 95 oil temp or above .
Just shows the bearings are worn but not surprising really .
