    Redline 20W50 too thick?

    I picked up 4qts of Redline 20W50 on the 75% off rack at AA for $2/qt. I have a 2005 Subaru Legacy GT that I've been using GC in. Can I lighten up 4qts of 20W50 enough with 1qt of 0W20 or should I use 2qts Redline with 3qts of maybe a 5W20? Don't know how thick the Redline 20W50 is.
