Dot 3 brake fluid autozone1/10/2024 ![]() ![]() It's also priced competitively for non-high performance brake fluid. It lasts 50 percent longer than traditional DOT 4 fluids and 10 percent longer than standard DOT 5.1 fluids. Compared to traditional DOT 3 fluid, this Bosch fluid lasts 100 percent longer. The “ESI” in the name stands for extended service interval, and that is the next key advantage of this fluid. That ability to use this fluid in so many different vehicles with different DOT grade requirements makes it a great choice for most drivers. In most cases, brake fluids only apply to one of the DOT grades, but this fluid from Bosch applies to the vast majority of modern vehicles. If your vehicle uses DOT 3, DOT 4, or DOT 5.1 brake fluid, the Bosch ESI6 brake fluid will work for you. If you have never purchased brake fluid, we’ve picked the best options and explained the pros and cons for you below.įor more information on the best brake fluids, refer to our table of contents. What factors should you consider when buying brake fluid? Do you need the pricier fluid or will the less expensive fluid work for your vehicle? If you want to replace your brake fluid on a budget, you can buy brake fluid for just about any vehicle online, but there are many to consider. One way to buy new brake fluid for your vehicle is to go to the dealership and purchase it from the manufacturer, but that isn’t always the most cost effective or convenient method. ![]() This process is accelerated if you are particularly demanding of your brakes, but even if you always drive your vehicle gently, the brake fluid does need to be replaced occasionally. However, it gets dirty from normal use and does break down over time, reducing the performance of your braking system. This is especially true with high performance vehicles or hard-working vehicles that put tremendous amounts of stress on their braking systems.īrake fluid is used in your car as part of a hydraulic system, not primarily as a lubricant, so it does not get dirty as quickly as motor oil or transmission fluid. Even though it is not changed on a regular monthly or mileage interval, it does need to be changed every two years. It’s generally not changed in short, frequent intervals like motor oil, although automakers do recommend changing it from time to time. Not a huge distance, but it really makes it my least visited parts store.Even drivers who take good care of their vehicles often forget about the brake fluid. The closest Autozone is about 20 miles away. The closest parts stores to me are Oreiley's, NAPA, and advance. If it somehow worked as a dot 4 + and dot 4 LV, that would be insane! I'll have to remember to check if I ever stop at Autozone. Now I wonder what the viscosity actually comes out to. If it is true, it would probably be excellent for applications requiring super dot 4/dot4+ or whatever they want to call it. The Valvoline dot 3/4 does have a lower boiling point than the Autozone fluid (according to their website). ![]() I think the Valvoline Dot 3/4 has a lower boiling temp. Pentosin is about $14, but it looks like Castrol Dot 3/4 might also meet that spec and if that Autozone brake fluid is real, it would also seem like it'd work and it'd be much cheaper, it should really be labeled a Dot 3/4. They do call for a 2 year brake bleed as standard maintenance. In that case, it's a 509 boiling temp with a 319 wet boiling temp. Mercedes has some weird spec that calls for Dot 4 plus, not sure what the exact boiling point numbers should be, but people are using Pentosin Super Dot 4 which they claim meets the spec. However, I wont spend $15 a quart for brake fluid when I've never had problems with the $7 a quart stuff Plus I really like metal cans for brake fluid. Also took a look at that Bosch brake fluid. If not, that's a terrific price for that level of boiling protection. Looking back at the autozone website, their 32oz of Autozone fluid has the same specs as the 12oz bottle. Claims 480F dry and 311F wet boiling points for only a little more than a 32oz bottle of standard DOT3. It's like $6 or $7 for a 32 oz bottle at Meijer. For a little added protection during spirited driving, I use Valvoline DOT3/4. Most standard DOT3 will work just fine for 99% of people. Regardless, unless you're tracking the car, using super high boiling point brake fluids is kinda pointless. I would need to go there and double check the bottle itself, sometimes they mix up stuff on the website. The bottles don't look entirely the same, and I doubt the Autozone "DOT3" actually has those specs. ![]()
