Hi, this is my first post. I have tried to search this site for an answer to my problem however could not find an exact answer.
I have a 2WD, 2012 Hilux with 35,000 kms on the clock. I have only just purchased the vehicle. It has full servicing history, however Penrite 5w40 semi synthetic diesel oil has been used rather than the Toyota/castrol stuff. I recently gave it an oil change, including a genuine Toyota oil filter. I asked the Toyota service department about the Penrite oil and they were happy that it exceeds requirements. Interestingly when I was asking about oil, the service manager said they use castrol magnatec. I noticed that this oil is not the recommended weight as per the hilux manual. The service manager said they use it because they can spread it across a large range of vehicles. Fair enough.
Anyway, my question relates to cold starting. I noticed, as per usual first start after the oil filter was replaced oil pressure took around 3 seconds to build. I have since noticed that it takes around 2-3 seconds for the oil pressure light to extinguish every time after cold engine starting. Is this normal? It seems like the filter drains after shutdown. I suppose it would as its upside down. I have read that there is suppose to be an anti drain valve in the filter. Is this true?
Not a massive fan of the engine running with no oil pressure. I do not rev the car when cold and the oil light remains off after initially extinguishing.
Thanks in advance,
Linton
