Been having my turbo rebuilt so car has been off the road for about 3-4weeks.

everything is sorted and back together so took it for its first slow test drive this morning...

what should a 2005 sti8 oil pressure be?

currently warm 90degree on defi gauge, oil pressure it showing 2.5bar. It goes up fine to a nice 6.5 on cruise and on WOT can peak near 8bar.

how low is too low? is around 2-2.5bar bad? cant remember it being as low as this but could just be me being paranoid after putting it all back together again and hoping nothing goes wrong lol

Mines on 3 bar, or a bit below when HOT on tickover, forged engine.

mine is the same as alcazar

also what revs does it idle at? as if it idles at lower reves, then there will be alittle less pressure

mine at around 800 ish revs on idle has around 2.7/2.8 bar when at 90degc
and 920 revs, it sits around the 3 bar mark

edited to say....

my oil is silkolene pro s 10/50

You really should quote the grade of oil when talking oil pressures!

The factory minimum spec is 1bar so you should be set

Need to do an oil change, can't remember off my head what grade in currently in there but probably a 10w40 fully synthetic will replace. Seems fine been sitting around 6-8 bar on warm up and driving then settling around the 2.5-3bar mark fully warm
