Thanks Chris C, sounds like that might be worth a look.

Hi Paul, hope you're keeping well!  Gauge still works, but accuracy is another thing.  I asked Caterham and they said as long as you have pressure showing and performance is fine that's okay?! Seems like a mechanical approach might be best for piece of mind - or i'll just stop worrying about it and carry on!

Interesting, thanks.  Seems you are right about gauge accuracy based on others experience.

I race a 310R, which started life in the 2014 Caterham Academy and worked up to 310R spec from 2017 onwards. I have always changed oil very frequently using 5W30.  These days, while oil pressure at cold is 4+ bar, once she is hot and at racing revs it is about 2.5-3.0 bar.  Performance remains good, but i am concerned about how much lower to let the pressure go before taking action.  I am assuming it is a matter of bearing wear after 6 years hard racing?  Is it time for a refresh and if so what to do?  I'm not sure a new engine would be affordable.

Any thoughts gratefully received!
