Hi Guys
Obviously covered this topic to death in my engine build thread, and as it turns out I have really good operating pressures as you would hope on a fresh engine.
And yes, I am paranoid about this now! So, as you know, it's been sub-zero of late. I have noticed on a frozen (literally) cold start up, my oil pressure light stays on for 3 or 4 seconds as the pressure builds, and it probably takes about 10 seconds to hit 4.5 bar, this is without revving it at all. A couple of taps on the throttle at this point and it quickly sees 5 bar idle, then everything is perfect after that once initial pressure is built up. Starting it when it's heated up, it only takes about 2 seconds to hit 5 bar.
I am using 10w/50 fully synth Total Quartz Racing oil. The oil is at max on the dipstick. I am using the correct Mann oil filter with 2 non-return valves in it. Is this oil maybe slightly too thick now for a fresh engine, is it the freezing temps, or a combination of both? Or is it quite normal in sub-zero temps? Or am I chasing an issue?
Thanks in advance as ever
Stuart
