I'd think it would be tough to tell as prob the shape is the same. It's the internal drain which looks different as far as I can tell.
My ecs order containing my parts shipped out today so when I do this repair I will take a pic of old dipstick tube next to the new, to see if there are any visual changes.
In any event like has been mentioned, for long term use in cold weather it's best to avoid short trips and run the engine hotter if can be. I find myself keeping the car in 4th gear on the highway on the drive home from work so she is nice and warm when I get home
Cross your fingers I make it out to work and back ok tomorrow, I had intended to park the X until doing my CCV but the wife has a meeting tomorrow and I have to take my own car to work.
