    i have a v6 2wd double cab tacoma 2006...door jam A04C..so i take it I have the LSD,,,also sticker says use LSD oil. So will the Royal Purple synthetic..be all in need, or do I still need a little additive???

    Since this is 2wd.. I can assume I only have to change a Rear LSD...?? I shouldnt have a front one right, thats only for 4 x 4 s ?

    No, there's nothing in front of a 2WD to put gear oil in.

    If you have LSD, you must use LSD additive or use a gear oil that already comes with it. (It will be labeled for LSD)

    If you don't, you'll end up tearing up the tires, differential, and maybe breaking axles, depending on how you drive.

    I'm not familiar with Royal Purple oils... Make sure the oil specifically states that it has FRICTION MODIFIER included in the oil. If it doesn't say that - then it doesn't have it. You'll have to put additive in the oil.

    I know Amsoil makes a 75W-90 Severe Gear oil that has the friction modifiers already in it.

    You are correct...a 2WD will not have a front differential.

    Read the manual, run whats recommended. You can run the priciest syn you want, but I'd search and see why non-syn is safe bet. Reg oil for LSD applications, no modifier needed, $10 for 3Qt, no issues. Its what your truck came with.

    I tend to agree that synthetic isn't warranted. I use syn oils because of good cold weather performance, and because they don't go stale due to contamination by combustion byproducts. Gear oil doesn't suffer that. It doesn't wear out quickly either, unlike engine oil.

    But those additives do wear out (the gears actually chop up the long molecules) so I think the best bet is to run regular gear oil with LSD additive, and change the gear oil more frequently than scheduled, or at least add some more additive between changes.

    But you don't want to over-fill the differential (it'll start to leak) so you need to let some oil out. At that point you'd might as well just change it.

    Does the manual say that you don't need friction modifier with regular oils?
