DOT 3 or DOT 4 it doesn't actually matter if it has DOT 3 in you can us DOT 4 what ever the case if you can use the next one or two up the only difference is when you get to DOT 4 or 5 is a higher boiling point
The difference between 7 and 3 is 4.
-1
At the earliest convenous you should bleed out the dot 3 and change it out with dot 4. More than likely the dot 3 will be fine but the difference is the dot 4 has a higher boiling point for extreme conditions. So while the dot 3 is in the system no racing or towing and the system will be just fine. If you boil the dot3 fluid in your system the brakes will become very soft or squishy.
Dot 3 or Dot 4Dot 3 or Dot 4
is super dot 4 ,compatable with dot 3 and dot 4 break fluide.
Dot 3 or Dot 4Dot 3 or Dot 4
You can use DOT 4 in place of DOT 3 but don't use DOT 3 in place of DOT 4. DOT 4 has a higher boiling point than DOT 3. DOT 4 is in there for a reason.
It's ok , dot 4 is an improvement formula from dot 3.
