My car basically hits 180, sits there for a while, then goes to 190, then to 200... maybe 205 and then back to 200ish.
in about what time? and running freeway? or traffic? at what speeds? outside temps?
205 is fine.....but you didnt tell under which conditions... it may vary , if going 80 and then to a traffic light ,or slow traffic for awhile after ran for 30 minutes...even up to 220 at that would be ok, then down to 205 driving again....assuming hot weather too... 205 in cold weather may not be too good.
