Ok sorry for the newb question, but I am coming from a BMW where there isn't even a temperature gauge anymore - the tachometer redline changes dynamically on the BMW depending on oil pressure and temperature.
Leading evidence: 'Run 5w-50' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace dynamically' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Ok sorry for the newb question, but I am coming from a BMW where there isn't even a temperature gauge anymore - the tachometer redline changes dynamically on the BMW depending on oil pressure and temperature.
Are there any guidelines on engine RPM depending on oil pressure and engine temp?
Thanks
Manual says don't go over 4k rpm until temp is at around 180. But that's coolant temp. Oil temp may take a little longer which is more important. I usually wait about 15 min of driving to insure this.
I've got the same "problem". Just take it out for a longer drive on the weekend where you can run the engine up and down and take a long route home from work every so often.
You'll have to change the oil more frequently though, say 5000 miles as a minimum.
Plus Juan. Short trips where the oil does not reach operating temps may increase engine oil consumption.
Regarding oil pressure, the rule of thumb I've heard is 10psi for every 1000rpm (up to a point) when the oil is at operating temp.

Ok this is what I've observed.
When I first start the car the engine temp is at the left most position and the oil pressure gauge is at 5.
After driving 15 mins or so the engine temp is at around 180 and the oil pressure gauge is at 3 or so at idle.
That's the only time I feel comfy going above 3K RPM.
First, is this normal behaviour (the oil and temp gauge correlation) and if so am I being too conservative?
2-3 bar at idle once the engine warms up is normal. So is 4-5 bar idle at cold.
Getting 2-3 bar at idle is a good indication that the oil is warmed up and not just the coolant.
It takes awhile to get 9 qts of oil warm, so be gentle on it until it does get warm.
