    Amsoil MTG or Redline MTL mt 82

    Is there a better one out of the two or are they pretty much both equal?
    Wouldn't amsoil in theory offer more protection than redline 90 vs 80 hot weight? Or am I totally wrong in this regard.

    Living here in NC sometimes we have temps as cold as 20's rarely though.



    This is the correct Amsoil correct? AMSOIL Manual Transmission & Transaxle Gear Lube 75W-90

    This is the correct redline?

    I believe you use the multi-vehicle atf, at least thats for the older cars like mine. Friends tranny was whinning and after swapping to the the amsoil fluid it no longer whines. Good stuff.

    Correct for what vehicle?

    Also are you taking about filling manual transmission or a differential?

    I put Amsoil MTG (your link above is the correct stuff) in my car and noticed a big difference. My trans had a little whine out of the factory and the MTG seemed to quiet it down significantly. It is not totally gone but a noticeable improvement. I live in the high desert of Southern California and morning temps have been in the teens all this week. I've noticed the first 3-5 shifts of the day can be a little tough, but once the trans warms up everything is good to go. If I double clutch the first few shifts or pump the clutch a few times it seems to make those first few shifts a lot smoother. When the weather was in the 30's I didn't notice any degradation in shifting. Your weather in NC sounds similar to what I drive in out here so I would definitely recommend the Amsoil.

    Reserve Amsoil MTG for hot climates.

    Red Line MTL or Amsoil MTF Synchromesh for moderate to cold climates.

    MTG has shown signs of early morning cold notchy even here in Northwest Florida.

    Thing I'm worried about is less protection if I went with redline.

    What do you define as hotter climates?

    I haven't seen many people post about using Amsoil Syncromesh unless I wasn't looking hard enough.

    You must know that Ford dropped the viscous lubricant when the 2011 first rolled out. It was a cheap viscous lubricant, even more viscous than Amsoil MTG. The transmission had the grind of death.

    Ford changed the lubricant to a dual clutch lubricant that is less viscous than ATF. Red Line MTL and Amsoil MTF Synchromesh are BOTH more viscous than the new lubricant Ford uses from the OEM. You would actually be protecting your MT-82 better than the new Ford fill. Amsoil MTF has a far more robust anti-wear additive package than OEM as well.

    Give it a shot, it will shift better warm than OEM stuff. However, during the first 5 minutes of cold start driving, you may notice some notchy.

    Amsoil MTF Synchromesh is doing a great job in all climates.

    Depending on the climate and duration of use, I'd think it would do far better than what the OEM is putting in the MT-82.

    If you would trust the transmission to Ford's spec, you should more than trust it with Amsoil MTF.

    Would you suggest MTF over MTG in Texas heat?

    Winters "dip" to about 40s-50s and summers avg 100-105.

    I live in the Phoenix area and we go from one extreme to the other. It's been down in the teens in the winter and can get to 120 in the summer. I am currently running Amsoil MTF and I seems to take a while to warm up in the winter. I am wondering if I should be running mtg as more of an all around fluid. Let me know what u guys think.

    I would trust Amsoil MTF Syncromesh in all climates. It's more viscous than ATF that's commonly used in Tremec transmissions, and has a very robust additive package.

    I wouldn't be surprised.

    To everyone wondering about MTF vs MTG just simply listen to UB and know what he says is FACT.

    I ran both in my MT-82 and MTF is def the best all around fluid. If you are gonna be in any kind of cold climate simply use MTF.

    If you are only going to see a hot climate then use MTG. MTG is awesome for heat but you will get some grind or notchyness if the tranny gets cold for the first few shifts then its butter Mcbutterson.

    IMO if your car will ever see 50ish degrees or colder use MTF. If not then use MTG.

    FWIW I am using MTF and my car sees days as hot as 115+ degrees. Tranny shifts like butter always.
