Phila67 Posted May 9, 2016 Share Posted May 9, 2016 I have a problem with my oil temp and pressure. I keep getting both showing a warning. The fans are working with air conditioning on. Any reason why I would be getting the warnings. Oil checked and fine. It's only just started since the hot weather and particularly when stationary. Once I get moving the warnings disPpeAr Anyone got any ideas Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
martyc Posted May 9, 2016 Share Posted May 9, 2016 Oil getting too hot and pressure too low? Sent from the moon using telepathy Quote Link to comment Share on other sites More sharing options...
Greenmamba Posted May 9, 2016 Share Posted May 9, 2016 Have you checked coolant? Quote Link to comment Share on other sites More sharing options...
Phila67 Posted May 9, 2016 Author Share Posted May 9, 2016 Yeah. Coolant topped up and fine. The only thing I haven't done yet is check if the fans come on when engine running and stationary. If they don't, could this be the issue. How do the fans cool the oil? Quote Link to comment Share on other sites More sharing options...
Scooby1972 Posted May 9, 2016 Share Posted May 9, 2016 Wouldn't of thought fans would affect the oi,l coolant fans on these cycle every few minutes on a scooby when stationery especially in recent weather ,maybe oil grade is to thin or oil needs changing when was it last changed and do you no what grade was fitted,subaru recommend 5/30 grade oil but I was told by a well known subaru specialist it's to thin especially in hot weather ?

Scoobyghost Posted May 9, 2016 Share Posted May 9, 2016 The oil is cooled at the modine by the coolant. If the coolant gets too hot it won't cool efficiently and could end up transferring heat. 1 Quote Link to comment Share on other sites More sharing options...
martyc Posted May 10, 2016 Share Posted May 10, 2016 I found that with 5-30 when hot at idle pressure could drop to 16psi, now I've changed to 5-40 it's more like 23psi. Also if it's aftermarket gauges just double check that the warnings aren't incorrectly set and going off too early.

Phila67 Posted May 10, 2016 Author Share Posted May 10, 2016 Oil is millers 5/40 and full change 3000 miles ago. Gauges are prosport. I'm due to do a full oil change soon. Would it be recommended to change grade? Would there be a way of testing the gauges to see if they are reading incorrectly.

Scooby1972 Posted May 10, 2016 Share Posted May 10, 2016 5/40 is fine for all but the big power scoobys millers is great oil but always use a genuine black oil filter from scoobyparts or icp...as someone else mentioned the gauges might be set to alert to a problem at to low a pressure or temp which has been highlighted by hot weather not sure how you adjust those gauges maybe someone with them could help...have you now checked cooling fans are coming on without air con I, m sure if they weren't car would have seriously overheated in recent hot weather i think it's the gauges need that adjusting presumably you,ve not had any dash light warnings as well...☺ Quote Link to comment Share on other sites More sharing options...
