Nobody seems to carry this in the local stores anymore. According to my very good friend, mechanic, and road racer, he likes this the absolute best and has been using it for years in all his two and four wheeled vehicles and those of his kids and their friends. We used up the rest of his bleeding the brakes on my truck and ran out. So I owed him one but gave him two for the trouble. He’s happy so I’m happy.

There isn't much cost difference between Castrol brake fluid and say, NAPA, so I use Castrol. Independent parts suppliers recommended this product line to me. I understand all manufactures are to conform to specs but I prefer buying Castrol. Can't hurt/ might help?

This is a great little bottle to keep in the trunk of your car. It's important that you bleed your brake and replace the brake fluid every time you get your brakes changed. You don't really need all that much. When it comes to brake you want to make you have the good stuff. Also, keep in mind that this is dot 4. You might when to check only to see if your car used dot 3, 4, or even 5.

Great price and size, like to keep these around for various jobs without leaving a half opened bottle too long. Good size for intermittent use, if you are doing a brake flush get a bigger size. Good quality from a brand i trust.I did have an issue with one bottle leaking during shipment, Amazon was quick to correct.

Works fine. A nice halfway viscosity for use in both Dot3 and Dot4 systems. I suspect most daily drivers will convert well and you'll only have to keep up with one fluid. Ratings will change if troubles arise from its use but have this in my Motorcycle and soon my car.Price was good but then jumped. Buyingbin bulk and doing several vehicles may be the way to go.

I am sure the brake fluid is adequate quality. Convenient, it got here in one day and I don't have to go to the auto store, currently self-isolating as much as possible. The container leaked though, probably just as it arrived as it was only enough to wet one corner of the box. There is a foil seal under the cap. Cap was slightly loose and the foil seal had detached about a third. 1 bottle, not wrapped, in the box with a couple air bags. Some anti-seize paste arrived in another box at the same time. It was packaged the same except the bottle was in a baggie. No big loss, less that an ounce I think but, could have been a mess if it leaked in transit.
