A quick question for the aftermarket turbos among us - what oil are you now using, and how's your oil pressure at full operating temp?

I'm using the Castrol oil for 'hot 4's and turbos' - comes in a gold coloured container. I just noticed the other day that my pressure at idle once warm is a bit lower (about the 1 mark) than it used to be pre-turbo (just less than 2) - it is fine at startup, so the oil is thinning a bit when warm (obviously). Pressure when driving is normal - just under 4.

What are others using/getting?

I have Havoline Semi Synth 15/50 from Big W
I get just on or over 2 on idle (depends if AC is on or not) when hot.

It is a lot quieter that it was before (read lifter noise, it sounded like it had a diesel factory option on mine ).

I was using Magnatec 10/40 before (pre turbo).

I'm very happy with the Havoline, but it is only freshly changed.

PS: It was under $30 too

Mobil 1 - 5w-50

Just below 2 when on idle, around 6 at higher revs before completely warmed up and closer to 4 once warmed up.

Not burning any oil and it seems to be staying pretty clean between changes. I try and buy the oil when super cheap is having a sale.

Motul Turbo-Light (which they don't make anymore... )

I have the same characteristics as you UA.

Boags

Likewise, im using Motul Turbo light and getting similar results. When warmed up it idles in the 1's (slightly lower than pre turbo) and is up around 4 in general driving.

I've been using turbolight cause I had a stash of it, butfound low pressure at low RPM/idle too.

I have moved the shell synthetic stuff (cant remeber name) and all is well, just below 2 once warm.

Shell Helix Ultra. Cold the pressure is at 4kg/cm2, and warm it's at 1.9-2.5.

Yeah I think that's the stuff I'm using now.
