Mixing Oil

[ludey dudey]

Probably a stupid question so take it easy on me...

i believe i currently have some random 5w30 in my 2005 wrx ppp however on advice from oilman ive ordered some 5w40 to top it up from time to time - my question is: can i use the new stuff as a top up keeping the current oil in, it was changed only 10-12 weeks back at the garage & seems overboard to dump the lot.

 

cheers

Should be fine if only topping up
