welshpug 1,626 Posted November 23, 2014 normal 75w80 BV oil. Share this post Link to post Share on other sites
wicked 103 3 Cars Posted November 24, 2014 I added Limited Slip Friction Modifier to the standard 75W80 oil: http://www.redlineoil.com/product.aspx?pid=41&pcid=4 I think it's bit more quiet at cold temps, but could also be that the plates have run in now..

boldy205 74 Posted November 24, 2014 Is it recommended to change the oil at more regular intervals with a plate diff? Share this post Link to post Share on other sites
borufus 17 4 Cars Posted November 25, 2014 I'm reliably informed that if I use anything other than the original oil then the fear change will be stiff especially when cold Share this post Link to post Share on other sites
camgti 56 Posted November 27, 2014 Yep. And if its thicker it makes the syncros work much harder. Stabdard Pug oil is the best. Cam Share this post Link to post Share on other sites
borufus 17 4 Cars Posted November 27, 2014 Think I'll go for the standard oil, thanks everyone! Share this post Link to post Share on other sites
allanallen 528 2 Cars Posted November 27, 2014 (edited) Is it recommended to change the oil at more regular intervals with a plate diff?I'd say yes, particularly if it's a competition car. Mine probably got changed 3 times in 3000 miles for various reasons and it was very s*itty every time. And thinking about it, it's essentially the same as my enduro bikes clutch, ie friction plates running in oil. Gearbox Oil change intervals on my bike are less than 1000miles......

wicked 103 3 Cars Posted November 27, 2014 (edited) Recommendation from KAAZ (my plate diff) How often should I change out my differential oil?It depends, our recommendation for street vehicles rarely driven on tracks should be changed every 3,500 to 5,500 miles or every other motor oil change. Racecars may need more or less oil changes, this is dependent on vehicle usage as well. Some general enthusiast may not know that differential oil can sometimes reach temperatures of 350F/180C at which point most oils will breakdown. Once operating temperatures reach this degree, viscosity levels will lower therefore not providing sufficient lubrication for differential operation. Do not be fooled by others suggesting oil's should not be changed for 20,000 miles...like your engine, differential's produce friction and wear, provide your differential a clean and healthy operational environment.

petert 554 Posted January 10, 2015 After being disappointed with Castrol Syntrax, Redline Shockproof and Mobil1 75W90 with the Tran-X, I decided to try a mineral oil plus Redline friction modifier. After some research I discovered the others were GL-5, which is not good on synchros. I ended up with Castrol VMX-M 75W85 (GL-4) and 2% Redline. I'm very pleased with the results. Silky smooth, slick changes and hopefully no more sludge. Share this post Link to post Share on other sites
wicked 103 3 Cars Posted January 10, 2015 I use Kroon Gearlube RPC + Redline friction modifier; mineral oil.... I was told that you need mineral oil with a plate diff, since synthetic oil will ruin your plates. http://www.kroon-oil.com/en/catalogue/product/335/gearlube-rpc-75w-80w/28/ Share this post Link to post Share on other sites
Biggles 65 Posted January 10, 2015 I run Total BV 75/80 in my BE with a Tranx diff. No issues. It gets changed every 3 or 4 rallies so 150-200 competition miles. Share this post Link to post Share on other sites
Ams 23 1 Cars Posted January 10, 2015 (edited) I use Fuchs Titan Sintofluid SAE 75/80 on a plated LSD for the sake of the aluminium synchros. It's on a road car though so change intervals will be less frequent since the box/LSD has an easier life. Personally If I was to go on track I would change it soon after.

dobboy 231 2 Cars Posted February 2, 2015 I've bought Fuchs Titan Race 75/90 for my VTS box which i think is recommended by Quaife as the box has a Quaife diff. A fellow GTI owner (AMS) mentioned it might not be ideal for the internal gubbins of these boxes. (My thinking was a £40 box v's a £600 diff, i should go with what the diff manufacturer recommended.) Anyone see any problem using 75/90? I don't particularly fancy a heavy gear change (or sending the oil back), would the friction modifier help in any way?

Anthony 1,000 Posted February 2, 2015 A Quaife will be just fine with standard 75W80 oil from Pug. It's plate diffs that have the conflicting requirements, although I always ran standard oil with mine with more regular changes. Share this post Link to post Share on other sites
