Affleck Posted April 26, 2019 Share Posted April 26, 2019 Can anyone explain why the oil level on my Outback has to be checked exactly after five minutes after switching off. I do this every time without really knowing the reason apart from it says so in the handbook! Quote Link to comment Share on other sites More sharing options...
mattiekane Posted April 26, 2019 Share Posted April 26, 2019 I don't know why exactly 5 mins, but you usually wait to allow oil to return to the sump.HthLoud pipes save lives Quote Link to comment Share on other sites More sharing options...
Affleck Posted April 26, 2019 Author Share Posted April 26, 2019 Yes I realize that but it says not to wait any longer than five minutes because you will get a false reading Quote Link to comment Share on other sites More sharing options...
mattiekane Posted April 26, 2019 Share Posted April 26, 2019 Is it the bit that says 'oil level should not be check for at least 5 minutes after shutting engine off, see section 3 of the owners manual for more information.'Loud pipes save lives Quote Link to comment Share on other sites More sharing options...

mattiekane Posted April 26, 2019 Share Posted April 26, 2019 I have no idea of the exact reason they wouldn't want you to check it after 5, it could possibly be todo with heat soak from other engine components at a guess.Sorry I couldn't be of more useLoud pipes save lives Quote Link to comment Share on other sites More sharing options...
Affleck Posted April 26, 2019 Author Share Posted April 26, 2019 Extract from handbook......For diesel engine models make sure to check engine oil level 5 mins after engine stops . Waiting any longer will prevent accurate oil measurement....page 11.20...When I check in accordance with book its ok if I wait say 10 mins the level rises. There must be a reason but I don't know what it is. Quote Link to comment Share on other sites More sharing options...
shms Posted April 30, 2019 Share Posted April 30, 2019 might it be to do with the baffled sump ? 1 Quote Link to comment Share on other sites More sharing options...
Affleck Posted May 1, 2019 Author Share Posted May 1, 2019 I'm not sure what that means. I've asked a Subaru garage here in Spain but they don't seem to know. Quote Link to comment Share on other sites More sharing options...
mattiekane Posted May 1, 2019 Share Posted May 1, 2019 I'm sticking with heat soak into the oil causing it to expand and giving you a false readingLoud pipes save lives Quote Link to comment Share on other sites More sharing options...
