UK based here I’ve posted here before about Subaru engine oil....well I’ve just had my car serviced at one of the most respected Subaru engine builder/tuner in the UK and he put 10w50 in my Forester XT....the Subaru specialists in the UK here like RCM and Scoobyclinic don’t even sell or recommend lower than 10W50 or 10W40...so If anyone knows a thing or two about Subaru engines is going to be RCM...
Now my dad who is a very respected mechanic (does not live in the UK so he can’t service my car ) is absolutely adamant I need to drop the 10W50 and swap with 5W30/5W40 ASAP...he’s a bit old school stick to the manual kind of guy
Reading on about it at one point subaru factory fill in Japan was 10W50...any advice on this anyone also use 10W50 the specs for the oil are below....and the Subaru manual specs 5w30 up to 20w60 for severe environments/usage whatever that means....
Car is a 2008 EJ20 petrol turbo 230BHP 56k miles...
