I need to bleed my system. Think I got a little moisture in it from detailing under the hood.

I know I need to use a DOT 3 rated fluid. Dot 4 could also be used as it is just a higher temp rating. Does anyone have any recommendations on fluid brands? I was looking at either the Valvoline Syntec or the Castrol LMA. I saw some Castrol SRF, but it was VERY expensive.

Thanks,

John
