There motor oil isnt terrible, spend the extra $1 and get Prestone or Valvoline.

Supertech is probably made by one of the major suppliers, and because every DOT3 brake fluid must meet the same standards their isn't going to be a big different between them, I'd trust it.

Use it, its fine. Brake fluid is brake fluid, they're all synthetic and meet the requirements listed on the bottle. Hard to tell the difference.

Check To See That The Oil Jugs You Buy Have The Exact Amount Of Oil In Them And Have An Inner Seal Under The Cap. I Use Mobil 1 And Fram Ultra Filters

The best DOT 3 fluid is DOT 4 fluid.

Genuine GM fluid, as it has a special long life additive unique to GM.

Note that there is no published recommendation on most GM cars or trucks for brake fluid flush. That's a clue.

I hear Motorcraft's DOT 3 fluid has the highest boiling point of any non racing .3 fluid,
500° IIRC.

You are correct. I sell a lot of it to road racers who use it just for that reason.

Well...the DOT brake fluid specs are minimums. Some brands exceed the minimums. The Ford brake fluid has a higher dry boiling point, so it is great for racers who change their brake fluid often. It has a mediocre wet boiling point. It is no benefit for those of us who change the fluid every two years or longer or never. DOT4 fluid is a slightly different chemical composition (that's how they get the higher wet boiling point) and might be incompatible with the elastomers in some brake systems. I suspect that DOT4 caused the seals on my Toyota master cylinder to fail before its time.

Wearever is BOGO at Advance right now. Just get that, fluid is fluid as far as the average car is concerned. I got 4 quarts last month on that BOGO deal and thoroughly flushed my Explorer's system.

+1. Why buy dot 3 when dot 4 is only slightly more and has a higher wet boiling point?
