    Mostly stock for now, I have added a cb radio, various cheap mods and I plan on adding aftermarket wheels and other items in the future.
    Read this thread, and it will give some good suggestions. I think a lot of those guys with LSD's are running dyno oil with the LSD additive.

    EDIT: I'm not sure what brand most of them are suggesting but any name brand dyno oil should be good, but read the thread and it will have some suggestions.

    As long as it's the correct grade (80W-90) the brand shouldn't matter. As for as the LSD additive, I went with Lubegard :

    I currently have Valvoline 80w-90 + Motorcraft LSD additive in my truck. Works fine.

    Before, I had 75w-90 and NAPA LSD additive. I was getting the groans in the morning.

    My local dealership sells Kendall 80w-90 LSD Gear Oil. Only $4.99 per qt.

    I've used Amsoil Severe Gear oil in our corvette LSD rear. Works great.
    It already has the additive in it.

    Just double check it's the proper specs for tacomas. I'll probably use that in mine when its time to change - assuming it meets recommendations (I haven't looked myself).

    If you towing go with some good synthetic. Like Mobil Delvac 75w-90. Make sure you have good amount in Diff as it will need it to keep it cool.

    I highly recommend the Redline gear oil with the additive already in it. After going through many oil changes and additives , this is the only one that has worked for me.

    I dont know how good Amsoil is, I tow it too but I have LSD so it was hard to get oil right. Delvac worked with GM additive and it is used in 18 wheelers so its good assurance that if you tow it can handle towing.

    I just finished replacing my front and rear diff, and my transfer case with royal purple. I was kinda hesitant about spending $20 a quart, but living in Alaska, cheap synthetic is still expensive. Anyways, I test drove it and I will always use Royal Purple. Remember your first ride in a car with brand new tires installed? Less hummin, smoother drive? Its kinda like how I felt when driving with the Royal Purple. also, if you have the TRD Sport, it already has the LSD additive. My truck only has 15k but I felt that my rear diff had water in it after driving through 3ft of water this summer. come to find out, it didn't have any water. I still do not regret changing my fluilds though. Royal Purple has a new fan!

    Just noticed the guy has a 2010 and he has an AUTO LSD and doesn't need any friction modifiers.
