I've been losing sleep over my hot idle oil pressure. Just about 1 bar. It's been doing my head in :roll: even though I'm not getting any low pressure warnings.
And then today, looking up the last service (done by previous owner) I just about made out a scrawl of 5W30 on the mechanics notes. On a 3.4 with 107k miles. :wack:
The service was done only a few months ago but this oil needs to come out pronto!
I'm juggling between 5W40 or going the whole hog , Millers CFS 10W50.
Thoughts?
Also, any guesses as to the sort of hot idle oil pressure increases I'd expect using the above oils?
