Best Gear Oil

[mmt 15]

Hi guys,

What is considered to be the Best gear Oil with a plate diff installed? Race only.

 

Which Oil do you guys use ?

[welshpug 1,661]

standard synchro gearset and you need to use normal 75w80, you can add some redline friction modifier to quieten the plates down, ensure it is not EP type oil.

 

Total have supplied the BV oils to PSA for years, it has been changed recently to a straight 75w formula which is backwards compatible with all BE and MA boxes.

 

if its a dog gearset then go with whatever the diff manufacturer recommends, this tends to be very incompatible with peugeot synchros.

Thanks. Not too worried about plate noise:-)

 

Would a Castrol Syntrans V FE 75W-80 be suitable?

Or Would a Castrol Axle Z Limited Slip 90 be better?

go to your local motorfactor or dealer, get 75w80, will be far cheaper.

I've been using Penrite Pro Gear 75W-90 for a while now. It already has some friction modifier built in and seems to play nice with the synchros. I found that Castrol Syntrax was definitely not compatible with BE1/BE3 synchros.

The syntrax is full synthetic; afaik you should avoid full synthetic.

[welshpug 1,661]

if they do a standard 75w80 then yes...

[welshpug 1,661]

The syntrax is full synthetic; afaik you should avoid full synthetic.

you may be right with that, the comma 75w80 i picked up yesterday for a be4 box in a 407 is mineral to gl4 spec.
