Oil gets thinner at high temperatures, so the lower pressure is normal. 1/2 bar sounds a bit kind of low, i don`t know the factory specs though.

The gage is from a 996 and the sending unit is also. The sending unit is new. Both are made by VDO. I think the gage and sending unit are a match.

I find that the 03 boxster oil pressure is indeed between 5 bars cold and 1 bar hot at idle.

This seemingly low oil pressure at idle is acknowledged in the forum and most recommend the oil pressure relief spring and cylinder be upgraded.

Thanks for all the responses. Will let you all know if the upgrade works.
