Topping off power steering fluid ok to mix?

Hey guys,

I was checking the fluid levels to make sure all is good and I noticed that the power steering fluid level is right at the minimum cold level. The truck hasn’t been on for a few hours. The truck is a 2018 and has 89k on it and the power steering fluid looked clear and clean(light yellow) so I’m guessing the previous owner had it changed not too long ago.

I have no idea what fluid is on there and I can’t find the info anywhere so I was wandering if it’s ok if I buy any compatible fluid and just top it off a little?. Not sure if it’s ok to mix different fluids?. I know Toyota sells a compatible ATF. Shall I use that or something else. Any recommendations?. Any help would be appreciated!.

 

When it comes to fluids and many parts, like sensors, PVC valves and other important parts. I only use factory OEM supplied. It may cost more but you can feel confident about it's computability.

That said there are a couple of fluids I don't buy from the dealer, motor oil and differential lubricants. I do believe when the time comes I will use OEM for the transfer case.

 

Don't mix fluid types. The fluid amount is still within spec, I wouldn't touch it. Just keep an eye on it over the next few weeks to make sure it's not leaking and call it good.

 

Odd that it looks clear/yellowish as it should be pink. Are you the original owner? Does somebody make an ATF that's not pink?

 

My OEM power steering fluid was clear/yellowish at 20K miles when I bought my 2005 Tundra used . . . ?

 

I am the second owner. I’m guessing it’s the Toyota OEM fluid. As far as I know it’s yellowish/clear. I don’t mind changing it. I’m just confused as what to put in there.

 

I just changed the transfer case last week with OEM Toyota 75w transfer case fluid. Sure it was expensive but when it has to be changed every 60k miles, it’s not a big deal.

 

I did not know that. Thanks!

 

The above was sourced from my owners manual for my now antique 2005 Tundra.
I believe Toyota uses a specific fluid in the PS reservoir of new vehicles and some PS fluid coming from the auto parts store is clear in color as well.
In the olden days it was OK to use ATF to service your power steering unit.
I like to use a turkey baster to remove the fluid from the reservoir and service with fresh ATF.
I've had issues with old fluid being run too long in other Toyota products and this is merely cheap insurance against a repeat.
Of course, your vehicle is much newer than mine so your mileage may vary.
Maybe check your owners manual for more specific specifications.
