Synthetic in Portal boxes?
Posted: Tue Apr 03, 2018 4:33 pm
I'v been scrubbing this site and am finding very different opinions about oil that goes in the portal boxes.
Some say use whatever you got, some say stay away from synthetic, some say they use synthetic and its great. Some even say the Synthetic makes seals leak is an old myth from the early days of synthetic.
But most of these posts are form a while ago.
I think theres a consensus that Redline MT-90 is great for the tranny and that the HD Shockproof oil is great for the diffs and transfer case- but not on the portal boxes.
Has anyone run Redline shockproof HD in portal boxes for an extended amount of time with success? It sounds like the right oil for the job- but does it leak?
I don't have heavy tools at my disposal, so I'm trying everything I can to not have to do heavy rebuilding projects.
Any thoughts?
