Front Diff Issues Using Redline Oil

[JAP-JET]

Hey guys ive been trying to sort out this issue with my 260RS Stagea for a few weeks now thinking it was afm or spark related, but it seems as though when i changed the front diff oil i replaced it with Redline lightweight shockproof oil as what they recomended on their site but it seems as though it caused my diff to bind up for some reason and as i was cruising along it seemed to make the car surge.

I have now replaced it with Castrol SAF-XA and seems to have made it alot better.

Just wondering if this is an issue other ppl have suffered, because i have been pulling my hair out the last 3 weeks trying to figure it out.

You must have LSD in good condition at the front. I have heard it makes LSD operate like they're "tighter", so less friendly but better lock up.

Yeah well it would make my whole car shake under accelaration and ended up causing the 4wd light to come on
