How many "Bar marks" are on your heat gauge when warm?

[Wildrice]

Mine goes goes up to 4 bar marks & the fan kicks in quite often when I'm stopped at a light. Several vehicle but I thought it was at 2-3 bar marks normally last year. I was in the low 60's degrees temp today thus I'm concerned about the 80 plus temp days ahead hiss Summer. I added approx 10 oz of water although it's difficult to read the cold & hot lines on the radiator reservoir. The coolant looks like plain water to me--past experience --it had a green color. 50% anti freeze cools better than water.
so how many marker bars show on your heat gauge when the F3 engine is warm??

Should be only 1 gauge in the title but titles can't be edited--I guess
