Just got off the phone with Redline, and they recomend their 75-90 NS product, (pt# 58304)with NO friction modifier added.They said the MT 90 is GL-4 and the 75-90 NS is GL-5. He said our toploader calls for GL-5 and would not recommend MT-90.
As far as the rear goes, he said 75-90w (pt# 7904), this is also GL-5 but has friction modifier added.
I personally am not going to use the rear end product because I was told to stay away from synthetics in the rear, i don't know why, but it kind of stuck in my head!!!
As far as the tranny goes, I am undecided what to do, conventional or
synthetic.
If I go with conventional, what weight and what brand would be good?
If I go with the redline, what are your guys thoughts on the recommendations from Redline today?
