bear with me here, sure this has been up soo many times before..
my eyes are bleary with trying to diagnose a problem i'm having so i'm ruling it out with, from what i have researched, to be pretty much the best oil i can stick in the car.. those with a simlar ocd will appreciate where i'm coming from!
just to firm up those that are using redline are using the below:
10w30 for engine
heavy for diff
thanks for any help, this is driving me nuts..!

 

I used 10W30 for the engine for a while. Then it started getting too expensive.

I use Amsoil 10W30 now, which to be fair isn't far off the redline price.

I find my 2000 car runs happiest on 10W30.

 

Gearbox oil - Redline MTL 70W 80 - you need 2 bottles
Differential - Redline Gear Oil 75W 90 - only 1 bottle needed
