Power Steering Fluid Types
Power steering fluid types explained: ATF, dedicated fluid, synthetic formulas and Honda and Ford specs, with three bottles compared for the fluid change.
On this page
Power steering fluid types come down to a short question with a long answer: what does your car actually want in the reservoir. Some systems run on automatic transmission fluid, some need a dedicated power steering fluid, and some makers name a formula of their own. The listings in this guide show all three kinds, so match the bottle to the manual before you pour.

Power steering fluid types: what sets them apart
The first split is between automatic transmission fluid and a dedicated power steering fluid. Some steering systems are built to run on ATF, and some need a fluid made for steering alone. The Bar’s Leaks listing in this guide covers both sides: it states compatibility with all types of power steering fluid or ATF, including petroleum, mineral oil and synthetic formulas. That breadth makes it a topping-off and repair product rather than a fluid for a full fill, since it is an additive meant to work with whatever fluid is already in the system.
The second split is between a maker-specific synthetic formula and a general fluid. The Lubegard listing is a complete synthetic power steering fluid, made for Honda and Acura power steering systems, including 2007 and up vehicles that require a fully synthetic formula. It also lists suitability for 2012 and up Ford Super Duty vehicles that take Ford High Temperature Power Steering Fluid, Motorcraft XL-22. The Johnsen’s listing is a general power steering fluid and conditioner in a 1-gallon size, with no maker fitment stated beyond the name, and its base type is not stated. In plain terms, a power steering fluid works as a hydraulic fluid: it carries pressure through the steering system, which is why matching the maker’s formula matters more than matching a brand.
| Type | What the listing says | Example in this guide |
|---|---|---|
| ATF in a steering system | Some systems run on ATF; check the manual | Bar’s Leaks works with all types of power steering fluid or ATF |
| Dedicated power steering fluid | Fluid and conditioner made for steering systems | Johnsen’s 4611, 1 gallon |
| Synthetic power steering fluid | Fully synthetic formula for named systems | Lubegard 24201, 1 gallon |
| Maker-specific formula | Honda and Acura, plus named Ford systems | Lubegard for Honda and Acura 2007 and up, and Ford Super Duty 2012 and up |
The listings leave gaps worth noting. The Johnsen’s listing states no vehicle fitment, so it suits an owner whose manual names a general power steering fluid rather than a maker formula. The Lubegard listing states no weight or dimensions, and none of the three listings states a warranty term. The Bar’s Leaks spec table lists an item weight of 1.2 pounds without saying whether that figure is per bottle or for the pack of 4 bottles of 16.9 oz each. Our can you use transmission fluid for power steering guide covers the ATF question in more detail.
What the owner’s manual decides
The manual is the authority on power steering fluid types for your car. It names the fluid the system was built for, and the bottle you buy should name the same type or the same maker formula. A Honda or Acura owner whose manual calls for a fully synthetic formula has a direct match in the Lubegard listing, which names Honda and Acura systems including 2007 and up vehicles. A Ford Super Duty owner whose manual names Ford High Temperature Power Steering Fluid has the same match in the same listing, which names 2012 and up Super Duty vehicles and Motorcraft XL-22.
If the manual names a general power steering fluid with no maker formula, the Johnsen’s listing fits that slot: a 1-gallon fluid and conditioner with no maker fitment stated. If the fluid is low and the system needs a top-off, the Bar’s Leaks listing fits that job: it is made to top off the existing fluid when low, or to add a bottle when changing fluid. Do not pour a bottle into the reservoir on the strength of the brand alone; the manual’s fluid type comes first, and the bottle’s stated fitment comes second.
The gear for the job
The bottles below cover the three kinds above: a repair additive for topping off, a synthetic fluid for named Honda, Acura and Ford systems, and a general fluid and conditioner in a 1-gallon bottle.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
How to choose the right bottle
Start with the manual, then the bottle. Read the fluid type the manual names, then read the bottle for the same type, the same maker formula, or a stated compatibility with all types. The Lubegard bottle names Honda and Acura and the Ford Super Duty spec, so it answers the maker question directly. The Johnsen’s bottle names no maker, so it answers the general-fluid question. The Bar’s Leaks bottle names every type, so it answers the top-off question, and its dual cavity bottle and pack of 4 make it a shelf item for repeat use rather than a single fill.
Size is the last check. The Lubegard and Johnsen’s bottles are both 1 gallon, and the Bar’s Leaks bottles are 16.9 oz each in a pack of 4, which suits topping off. Check the manual for how much fluid the system takes before buying. A bottle that names the wrong fluid is the wrong bottle at any size, so fitment first, size second, and the manual before both.
FAQ: garage tools
Is power steering fluid the same as transmission fluid?
Not always. Some steering systems run on ATF and some need a dedicated power steering fluid, so the manual decides. The Bar’s Leaks listing in this guide states compatibility with all types of power steering fluid or ATF, including petroleum, mineral oil and synthetic formulas.
What power steering fluid does a Honda or Acura need?
The Lubegard listing names a complete synthetic power steering fluid for Honda and Acura power steering systems, including 2007 and up vehicles that require a fully synthetic formula. Check the manual for your year and model before buying.
Can I use any power steering fluid in a Ford Super Duty?
No. The Lubegard listing states suitability for 2012 and up Ford Super Duty vehicles that take Ford High Temperature Power Steering Fluid, Motorcraft XL-22. If your manual names that fluid, the listing matches; if it names another, match that one instead.
What does a power steering repair additive do?
The Bar’s Leaks listing describes a dual cavity bottle with additives for common power steering fluid problems: it lists noise reduction, smoother hard steering, leak stopping and rack and pinion reconditioning. It is made to top off the existing fluid when low, or to add a bottle when changing fluid.
How much fluid is in a bottle of Johnsen’s power steering fluid?
The Johnsen’s 4611 listing states a 1-gallon size, with an item weight of 7.73 pounds and dimensions of 10.0 inches by 7.0 inches by 4.1 inches. The listing calls it a high quality power steering fluid and conditioner.
