Hi everyone,

everytime I start engine after hours of inactivity (cold start), I notice that oil pressure light ('red oil can' on the dashboard - http://tinyurl.com/9zjmwf2 ) stays on for 4-5 seconds. That means motor has not been lubricated for such long time everytime engine is started after period of inactivity. Seems too long for me, as my previous cars Opel Astra, Kia, Mazda, etc. turned off that light almost immediately after engine is started. Motoroil - dexos2: GM 5w30 (previous) and Motul X-clean 8100 (now).

What could be the problem? Someone with Z18XER - how long does your oil pressure light stays on after cold start?

I thought about oil filter loosing oil when shut off for longer time (few hours and more). But then I asked mechanic to change type of filter, when he answered that they only change 'filter paper' itself, not complete housing. There should be nonreturnable valve, but I don't know if it can be changed?

Thanks for help.

Best regards.
