hi guys micky here have 2008 impreza 2.0L R  it has done 90 odd thousand miles and I change the oil every 5000 miles but after a while it starts putting some reek out the back it doesn't get hammered  is there an oil that I can use as I use 5w30. thanks

I think 5w30 is the right stuff for your car so im sure not that would cause that. Might be burning a bit of oil just check the level often. Check your spark plugs and if your really concerned get a mechanic to check it over. Best of luck bud

5 by 30 seems bit thin,, I use 10 by 40 millers motor sport  oil ,  but guy at rs motor sport where I get service done said ad be better with a thicker oil,  can’t remember what ratio he said though
