Millers TRX 75/90 g/box oil

[selfconfessedlunatic]

Hi only reason I'm putting this on here is if anyone is stuck on gearbox oil choice I cannot recommend Millers TRX 75/90 highly enough, I changed all the fluids in our Stag ready for the winter and after pondering what gearbox oil to choose eventually thanks to a comment made by a fellow Stag owner that he supports a british company I chose Millers. Today is the first chance I've had to drive the Stag since and I'm amazed at the difference in the gearbox. The changes are 100% smoother, overdrive better but above all not a sound from the box at all! Hope this helps someone in someway!

Hi Andy,

Thanks for that, it's very helpful to me.

I want to replace my gearbox oil soon and was undecided as to what to use.

I'm a big fan of Millers Classic 20w50 Semi Synthetic which I reckon is even better than VR1 so I'm definitely up for the Millers g'box oil if you've found it good.

Cheers

Any reason for choosing the Millers TRX 75/90 over the Millers Classic EP80W/90 ?

I have also been advised by other Rover gearbox users that the Millers TRX gear oils fixes the poor cold shifting on the LT77 gear box if anybody else is interested.
My set up uses the LT77 so was intrigued to see that the oil works for your Stag boxes too.

Great oil eh? I believe this is what Wards sells (the Classic Sport?). Saying that, there is alot of conjecture as to whether fully synthetics are suitable for older cars if you read many of the current classic publications (Classic Car Monthly for example this month) and through many of the specialists (Classic Oils and Opie Oils).

Hi Chas,

I wouldn't want to use fully synthetic in my Stag but this stuff is specifically semi synthetic. I reckon it gives the best of both worlds to an older engine.

Also, Millers specialise in older cars and they seem to know what they're doing. Btw this semi synthetic has something like 1200 ppm ZDDP

I'd be very interested to hear others thoughts or experiences - good or bad.

Cheers

When I had my MK1 with Rv8 and 5 speed SD1 box, Brighton Stag Specialist told me to use power steering fluid in the gearbox.

I have used TRX in my gearbox for nearly 5 years and I am extremely pleased with it. Smooth changes and little noise, though I can detect a tiny bit of noise starting in 1st at 150,000 miles.

[jleyton]

For those who've used TRX successfully in the gearbox, have you used the fully synthetic or semi synthetic ?

Cheers

Semi synthetic with J Type overdrive in mine.

I agree. It is one reason for why I try and use VR1 or Millers in the Stag whenever possible. I do wonder whether quite a bit of the 'fully synthetics are bad' argument for older cars comes from people having more cash than sense.

I know my last 944 was wrecked allegedly (or at least the garage thought it was partly to blame) by the PO using Mobil 1 0W40 (Not exactly ideal when Porsche specified 20W50 or 15W40 at the time in combination with the PO taking the car to Britanny during the summer months). Again, another friend of mine swore by Mobil1's 0W40 in everything (from Fords which were only really meant to run 5W30 to Golfs which should run 10W40 to 10W60 depending on use).

It seems a number of Fiat 5 pot owners damaged their engines this way too...

Just seen in a local Motor Factors Millers 20/50 for £45.50 per 5lts. don't think they sell much though

[jleyton]

Millers do a discount for Stag owners - ad is in the mag.

I'm very pleased with the price I paid for 10 litres of the 20w/50 Classic sport semi synthetic - only problem was their suppliers don't have a website which is a bit of a pain.
