Hi, the oil pressure switch normally switches off the oil warning light at 6psi
In an ideal world the oil pressure should a minimum of 14psi at idle when hot?
And a minimum of 40psi under load, on boost, greater than 2000 rpm
10psi is getting a bit on the low side, what do you get at 4000 rpm

Cheers

Steve.

Ps ADSRST how is the engine going
