...have a 1987 Toyota 4x4 truck. The axles and transfer box takes, 75W-90 GL5 (approx. 6 qts total).
I plan on using RedLine MT90 for the gear box. I cant afford to used redline throughout...
I don't understand. MT-90 is around $18/qt. Amsoil is around $14/qt.
I don't know the exact capacities of your front and rear diff and the transfer case.
I'll just use 4 for diffs and 2 for transfer. It may be more for the diffs. IDK.
4 X $18 = $72 for RL in gear boxes (5 qts =$90)
4 x $14 = $56 for Amsoil in gear boxes (5 qts = $70)
You'd have $16 savings in using Amsoil in the gear boxes.
Add that "free" bottle of Amsoil Severe to your transfer case
and you only need to add one more bottle of Amsoil for $14.
Well, actually on $12 more because you saved $16.
I'm not supporting either brand of fluid. 6 qts of RL at $108.
6 qts of Amsoil at $84. If my money is really down to where
I can use 4 qts of RL and then need to choose a cheaper
product for the other 2 in the transfer case I am really in trouble.
I probably wouldn't be changing any gear fluids.
Am I missing something? Aren't we talking about saving $10 if we
choose a cheaper transfer case fluid? Are you sure you can't afford it?
Aren't we are talking about $14 more if you go with Amsoil all the way??
I'm just asking. No ill will. Are you sure you have thought this through?
Maybe I stayed up to late last night and it's me that ain't thinking clearly?
$10 over 50,000 miles?
