Differential Fluid

2018 Tundra Crewmax 4x4. Has anyone ever looked up the differential fluid requirements for our trucks. I ask because I was looking for a suitable replacement for Toyotas 75w85. I have some Redline in the diffs currently. I came across Chevrons 75w85 for use in Daimler Chrysler and Freightliners. It has a service life of or upto 500k miles OTH and 300k miles for off highway use. I also know I’m talking to different types of vehicles axles but couldn’t you simply let the fluid go longer anyways? So I have to ask myself what is up with the 30k mile change interval? Manual says 60k but dealer says 30k. So much damn money and time wasted. I do my own service anyways but I just wonder about it.

If this topic is anything like the engine oil threads, it's on you to sift through the nonsense.

 

If a moderator could delete the post please. I just read the mile long post about it in the maintenance section.

 

Red Line is a top level fluid. I'm running it and plan to for 100,000 miles minimum. I think you've already got the best Jeffroski.

 

But those of us that need a 75W for the transfer case (2013 and up) are still going to have to go OEM or Ravenol? I didn't see anything from Red line for 75W.

 

What is wrong with OEM?

 

As far as i know just $$$$$ expensive. I used Ravenol when i changed mine at 30K.

 

The OEM fluid is engineered specifically for Toyota. Amsoil makes the best oil. I would stick to OEM.

 

I just did mine. Went with Redline due to this video.

Also, if you are in the Dallas area, I'll loan you the pump shown in the video as well.
