1993 Honda Accord Brake Fluid Type. What type of brake fluid is good for my 1993 Honda Accord - DOT 3 Synthetic or Mineral.

Mineral and vegetable oil brake fluids became obsolete many years ago apart from a very few exceptions and these were replaced by a universal glycol based type which is virtually the only type available from the majority of retailers.

Early glycol fluids had a relatively low boiling point and have been replaced by types with higher boiling points so currently there is generally two types available - in Europe these are DOT 4 and Dot 5.
DOT 4 is suitable for all clutch and brake systems (apart from a few exceptions) of low and medium performance vehicles and DOT 5 for the braking systems of high performance vehicles. Most people most of the time find DOT 4 a better all-round fluid and because the information surrounding DOT 5 (and 5.1) tends to be vague and suggests at least some are silicone based which can be harmful to some hydraulic seals.

The main problem with glycol based fluids is many braking hydraulic systems are vented to atmosphere and the fluid is hygroscopic and absorbs atmospheric moisture which lowers the boiling point. This is why a brake fluid change is part of the modern service and maintenance schedule.

I can't remember the last time I saw a reservoir cap that didn't say right on it what type fluid to use. If yours is unreadable, you can use DOT 3, 4, or 5.1 Most US made cars were using DOT 4 by 2006, VW was probably ahead of the curve. The primary difference between 3, 4, and 5.1 is boiling point. I would probably use DOT 4, because you don't want lower boiling point fluid than was intended for the vehicle design. If you add 4 to existing 3 you raise overall boiling point (good), where if you add 3 to existing 4 you lower it (bad).

DO NOT USE DOT 5 because it is silicone based and will not mix with glycol based 3, 4, and 5.1.

oil is API 5w/20 Honda recommends using all there fluids as they are supposed to be subpurb. to the others alot of this info is on the inside of your hood....auto tranny fluid Honda ATF Z1 or equivalent DOT 3 brake fluid....Unleaded gas 86 or higher octane.....Honda Allseason Anti freeze/coolant Type 2 ......50 50 mixture2.4 liter holds 4.4 quarts of motor oil....tranny fluid 3.0 quarts 4cyl

Any DOT 3 brake fluid, avaible in most retail giants and auto parts stores.

Hope helps with this (remember rated this help) Good luck.

You can use either DOT 3 or DOT 4 brake fluid.

Both are compatible but the DOT 4 fluid has the higher boiling point and is the better fluid to use.

(You cannot use the DOT 5 silicone fluid in your vehicle).

dot 3 is good.

Brake and clutch fluid use the same DOT 3 synthetic brake fluid.
