Planning to do a fluid exchange on our Fusion which Ford specs as using DOT 4 LV brake fluid. I can get Pentosin DOT 4 LV locally for $15-18 for a liter. I'm not against Motorcraft fluid but it's twice as expensive from a local dealer ($16 for a pint). I did an exchange on my G35 recently and used less than a liter to do that. Did I get 100% of the old fluid out ? Maybe not but others with similar models (or 350Z models) indicated they used between 750ml to under 1000ml so I feel okay with the amount swapped.

Is this Pentosin good stuff ?

On a related topic, anyone use something like this DOT 4 LV in a car that only specs DOT 3 or DOT 4 ? Pentosin, for example, says it's backwards-compatible, even the LV variety.

Pentosin is a quality fluid, believe it is still OE for some European makes. I don't think you would have a problem w/ LV on a relatively modern car. I would not use it on antiques or cars w/ primitive hydraulic systems (see my signature :-)), but you should be OK.

Pentosin is high quality. I would use that product any time if DOT4 LV is required.

Yes Pentosin is very good brake fluid. I flushed and refilled my wife's NB with it and have had 0 issues with it. My wife and daughter are in this car on a daily basis in crazy Mexico City traffic, and brakes get quite a workout here. Pentosin is one of the top 5 fluids I would recommend and use.

There is nothing wrong with the Pentosin LV, and yes it is backwards compatible smile

It's a sin if you skipped over the Pentosin for something else smile ATE SL6(also sold as Bosch ESI) is also good as well. The Germans(BASF and Clariant) are the main producers of DOT 4LV.

DOT 4LV is a almost universal fluid for any glycol-based system, it's backwards compatible with DOT 3/4 but it doesn't meet the wet/dry boiling points of DOT 5.1. However, some brake systems are best served with conventional fluids, if you don't have ABS/ESP it'll be of no benefit.

Or, you can get Ravenol DOT 5.1 on Amazon for under $15 for 1L bottle.... That's what I switched to in both Kias and daughter's Acura.

One benefit of LV brake fluid is it makes gravity bleeding a more realistic option.

I'd say it's perfectly fine, too. I'm using Castrol DOT 4 LMA in my G.

I realize I can mail-order it, but I've never seen Castrol brake fluid around here (in stores). I do like Castrol stuff too....

Just curious, how much fluid do you use when you replace brake fluid ?

For me, I gravity bled when changing calipers. All four wheels, went through no more than two and a half pints. For whatever reason, I can get the Castrol DOT 4 for something like under $5 a pint, jobber price, which is significantly less than DOT 3 from most retailers. I don't see it at most stores, but independent jobbers occasionally have it, since Wakefield (our Castrol) markets aggressively. If Castrol makes something, you can find it on the shelf here somewhere.
