And it's been answered plenty of times before, a search would have answered it quicker

I'm no oil expert , whenever i need any whether its diff,autobox,manual box or engine i simply input my vehicle details on Millers webpage then order the stuff from either Opie or off ebay & get my indy to do the change
Ive no clue what the Comma stuff costs but can't be much of a saving
like you i have no issue with millers or comma, so i am open to all suggestions.

ok im officially pissed off and utterly confused now,
i am going to change the gearbox and diff oils on mine and tugs zed, both 2005/6, both 6 speed manuals
i have spoken to both millers and opie now, opie says 75/80 in both gearboxs as 75/90 will be too thick and make for a stiff gearbox shift , while millers agree 75/90 should go in both cars diffs, millers say only my 3.0 needs the 75/80 and tugs 2.0 should have the 75/90 in front and back. wtf.... :cry:

i think im leaning towards millers 75/80 trx synth for the gearbox and millers trx synth 75/90 for the diffs - your thoughts ?

I just copied these Castrol info sheets through the Opies website. They are what I put in my gearbox and diff back in April '17. Never had a stiff gearchange or anything seize up or leak etc etc :thumbsup:

we are in the process of doing the gearboxes and back axles of out 2&3ltr e85's
having done mine i was shocked to find i had clean red fluid in the gearbox, seemingly newish but not in my 12 month ownership, any ideas what it was ? anyway, i put the 75/80 i had bought.
moving onto tugs car we were surprised to find no drain hole on his back axle.

it seems the humble e85 2.0 back axle dont have a drain plug just fill hole, unabashed we simply sucked it out with my pump, £8.22 off ebay and 2 meters of hose from B&Q, cut about 15" of hose which went into the bottle of oil, the other length of pipe went under the car and into the fill holes and that pushed it into the gearbox/back axle, simply reversing the drill allowed me to suck out the old stuff from tugs back axle., and then after doing both cars we went down the boozer ... stinking of transmission fluid .. so we were happy bunnies, the boozr was a bit full, so we had to park next to these..
