Good. The bottle was enough to bleed my brake ...
Good. The bottle was enough to bleed my brake system completely of the old fluid. Everything is working perfect.

Great brake fluid and does what it should
This is DOT 3 and for those of you that may be wondering ***all dot 3 brake fluid is synthetic*** so yes it works fine with what you have. I used mine in a newer truck and a classic car. Prestone is my favorite because it stays cleaner longer in my usage. I have used other brands that cause components to fail sooner so whatever these guys are making they are doing it right.

Clear is better than dark brown.
I’ve always checked the brake fluid level whenever the hood is up on my 1990 Chevy truck and that’s about all the attention it’s gotten. I recently replaced drums, rotors and pads on all wheels and the stopping didn’t improve all that much. I finally popped the cap on the reservoir and the fluid looked like diarrhea. I purchased it in 1998 and have done a lot of maintenance on it, including a new engine last summer, but I’m embarrassed to say that I’ve pretty much ignored the brake fluid. I purchased a Lisle 19200 Brake Bleeding Kit and a few quarts of synthetic Dot-3 brake fluid (enough to do my 1999 Expedition) and started the bleeding process one wheel at a time until all I saw was clear fluid. It was a day job because those 17-year old fittings needed some coaxing and replacing. I needed a backup quart so I purchased one at the auto parts store for 5-bucks but I made that 40-mile drive for other things but you can’t beat the convenience of ordering here while your vehicle is disabled and waiting for a part… or more fluid.

Great For DIY Auto Repair
After who knows how many years of use since the last brake fluid change, our '96 Camry was in desperate need. Rather than spend the ridiculous amount of money at a dealership, we did it ourselves. It was relatively easy to do, someone with limited mechanical ability and some tools could probably do it with a YouTube tutorial. There was no real difference in the way that the brakes felt, but at least we know that we won't die now. The Camry required 2 bottles to flush the old fluid, but it would have been nice to have 3 on hand.

Great product - one bottle should flush one vehicle's brake system
Flushed the vehicles brakes (didn't realize you are supposed to do this every 2 years!). One 32 oz bottle seems to be the right amount to do one vehicle. I did 3 vehicles with 3 bottles and all of them used about 31-31.9 oz. each to flush the brake system completely.

Good for most econo cars.
Most common brake fluid for passenger cars. if you have a racing car, and often stomp the pedal to the metal, or run a mobile home or RV, perhaps go with dot 5.1 fluid. Or if you just ride it sporty, DOT 4 might also work for you. But other than that, DOT 3.1 is more than enough to do the job for economy cars and commuters.

Don't drink it.
It's Brake Fluid. What can I say. My car was using more brake fluid then gas. I had the fill the master cylinder daily. Got all the brake lines replaced.

What's hot... what's Not
I was a brake and front end mechanic for a number of years. I've always use DOT 3 fluid on most applications. I realize DOT 4 had a much higher boiling point, but I've never had a boil over problem or brake failure as a consequence. I feel if your fluid is getting that hot, you are either over working your brakes, they are insufficient or becoming defective. I have seen where fluid has spewed from a weep hole in the reservoir, which actually served as a braking system indication of a problem. I suppose you could just up it to DOT 4, or see what's cooking.

Good value for brake fluid
Prestone DOT 3 brake fluid 32 Oz. is a good value for your money. It easily topped off the brake fluid in my 1996 Toyota Tacoma pickup truck, and solved the sensitive brake fluid level switch which had illuminated the brake warning light even though the levels were above "min" This is a common problem in Tacoma pickups.

Good stuff
Great brake fluid. Brake fluid does expire. So if you can buy smaller containers so they stay sealed if you don't need it all. Don't mix Dot 3 and Dot 5 so double check you car's break fluid. As always wear gloves this is not good stuff to get on your skin.
