    I put Amsoil in my 2014 F-150 with the 8.8 rear end. So far so good. Would use Redline or Royal Purple with confidence as well. Even the Supertech oil from Walmart would get the job done especially if you’re just daily driving but it’s nice to have that comfort of using a premium product.

    I just bought a two-gallon jug of SAE 80W-90 today. I also looked at some additives but I couldn't decide. Thanks for the tip on the friction mod product.

      If your 80W90 has an API GL5 rating It already has an extreme pressure additive.. If you have a limited slip differential differential or some other rear axle with multiple disc clutches or one clutch it will require an additive suitable for for the type differential you have

    I just changed my front and rear differentials fluids. I have a 2010 GMC Sierra with the LC9 and the Eaton G80 rear differential. I was amazed at how clean my read differential was. It has 146k miles on it and the fluid was dark, but the right consistency and the G80 was spotless. No signs of wear at all. Even the magnet had barely anything on it. I replaced the front and rear Diffs with Amsoil severe gear oil 75w90 full synthetic. I could swear they are making a tad bit of noise. They were dead silent before I changed the gear oil. Now I am concerned I should switch it out with the recommended GM lubricants although GM discontinued the original and the two revision lubes for the front differential. 😅

    I use Lucas, but then I wanna try some different so I switched to Amsoil 100% synthetic gear oil ran it for one year now and so far so good✌️

    Here's the short version for free. Use a brand name synthetic. Be ware of old pinion seals. use the correct weight. Use a "modifer additive" for clutches if u have them in the center section. This allows u to not worry about looking for the "LS" listing on the bottle(limmited slip).

    Did you say if you're using a "sure grip" gear oil you need the additive? Could you clarify that. Also, just watched a test of gear oils and Lucas failed, didn't meet industry standards, neither did Mobil 1. Is that a 1970 Cuda? Sweet ride for sure.

    • @backyardhotrods9885
      @backyardhotrods9885  Год назад

      Yes definitely need an additive. I’m using a Ford one Dr. Diff sells. Wow surprised to hear Lucas didn’t test well.

      Thanks for watching and commenting! I have never used Mystik I would say the most important thing is to use the recommended weight

    How do you drain the old gear oil?

    • @backyardhotrods9885
      @backyardhotrods9885  6 месяцев назад +1

      most rear axles you need to unbolt and remove the center section to get the old oil out. I drilled and tapped my mopar 8.75 rear axle and installed a small drain plug to make it easier to service

  • @RetroCaptain

    Non Synthetic is the stinky version. Old Synthetic won't smell as much.
    Its the additive you're smelling to diminish GL5 from GL4.
    Nothing about how old it is.
    If it's 90w GL4 it won't smell like GL5 90w .
    Cannot swap them around.
    They're separate purposes.
    GL4 for 3 speed transmission etc 4 whatever and GL5 for the axle only whether its a sedan coupe pickup or full floating pusher axle on a transport tractor. The clear window cups to oil the outside axle bearings

    Great video, but stay away from amsoil. Too much variance with the oil quality and viscosity.
