I would like to know, which oil/grade is recommended by vauxhall for the VXT......How many litres will I need. I have seached but found so much conficting information on what people use. All I want to know is what vauxhall recommend and then I can choose from that. I guess there will be some oils which are great but I see alot of it is down to personal preference. So if anyone knows of good/bad ones that will help aswell. Any Help is great

do NOT and I really mean DO NOT use Silkolen/Fuchs Syn 5 75W90 Fully synth.... its ok when hot and in summer, but in the winter it makes the box an utter slag to live with. I've had "frozen box" (oohhh errrrr) 4 times already this month lol. I am considering either a straight 75W fully synth (more a motorcycle oil) or a MTF (such as redlines MTF, or AMSoil, or Royal Purple). From reading US threads on the matter they are all going back to Dexron III, which is odd as its a very old "design" of oil now a days

[M3VXT]

I have been looking at using REDLINE D4 seems to fit the bill well. I have used syn5 in the past I agree it's a bit of a "tight box" when cold lol

[Duncan VXR]

I have the Silkolen studd in and not had any issues with the box, minus 4 a few times and lives outside in the cold The worst I have experianced is a bit stiff to get into reverse once when car was frozen solid but 2nd attemp fine???? Maybe teh M32 box does not suffer from the same issues as much?

[M3VXT]

Yeah not saying it wasn't usable just a bit tight first thing in the cold mornings.

Anyone got an opinion on this redline stuff below. Meets dexron III spec

REDLINE ATF D4

I'm having a chat with a transmission engineer tomorrow to seek his learned opinion

[M3VXT]

Well I have had a closer look the amsoil MTL looks like that could be a good one and comes recommend by a few other on here. Does turn out to be one of the more expensive £35 for 2.8ish litres, but not intending on changing it for a while, only drained it as I changed the clutch and flywheel. It would be good to hear what the transmission blokey says!!!

I have got the Amsol gear lube long life supplied by CMS and it has been fine and this year seems a little less tight that the standard stuff. Cheers Oakmere

[davep24]

GM discontinued the dexron III stuff and replaced it with part number 93165290, cost £4.04 plus vat per litre. Used it for nearly a year now a had no problems

Possibly relevent?:

I put in Amsoil. then run hot, then flushed and refilled with Amsoil to correct level, to be asured it was free from original oil.

The car had done 1Ok and by 16K the mainshaft/layshaft bearings were shot and second gear syncro/bulk ring damaged causing poor and then almost impossible selection of second gear at any temperature.

Result being gearbox overhauled...

Coincidence?

Unfortunately, after changing to this oil, a friend of mine who is a manual/auto gearbox repair specialist advised me he would have left the standard stuff in!

He then lead on to say the fully synthetic oil doesn't give as much protection.

Interesting you mention Dexron III, as he is now using this in his E46 M3 instead of the standard fully synthetic oil.

IMO after advice and the damage to my gearbox I would not use fully synthentic oil and stick with GM standard or a Dexron III equivilent.

Food for thought...
