Hi Guys.

As far as I'm aware the car was ran with 5/50W oil after discussion with a few guys I opted for 10/50W. Since doing so the car seems to take a few more seconds to start than it normally did.

Could this mean the 10 grade is to thick?

What year Impreza & engine size. I use 10w/60 on my forged cdb & wouldn't use a 5w/50 or the like

Most Subaru specialists would recommend 10/60 or 10/50 either millers, valvoline or the likes. Best speak to oilman @ opie oils.

Had a chat with him that's why I went for the 10W

In that case like I said keep with the 10w/50. Yes it's a slightly thicker oil.
