ripped_fear Posted March 22, 2012 Share Posted March 22, 2012 (edited) Hi all I'm treating my NA to allot of bits currently, and have now decided to do a gearbox oil change. My NA unfortunately has a W58 gear box and according to the oil guide, the recommended oil to use is 75w/90 with a recommended brand of Motul Gear300. I have been on to the trusty opieoil.co.uk web site as they are very help ful, and they have a variety of different ones to choose from for example 80w/90 Now the oil guide was made in 2006 and I know that better brands come about, so looking for some advise. Basically I want the best oil I can, as after some advise on engine oil last year I got pointed in a direction of a particular brand and consistency and the engine seemed to run even better than before. (Not sure if that was just in my head) So what oil is the best for the 5 speed, brand and consistency information appreciated and also what quantity is needed as this information is missing from the FAQ. Also should add the car is only used for road use and I'm hoping to get a couple of track events in this year. Thanks in advance Jake Edited March 22, 2012 by ripped_fear (see edit history) Quote Link to comment Share on other sites More sharing options...

Ricardod Posted March 22, 2012 Share Posted March 22, 2012 i heard people swear on royal purple gear oil on supraforums. redline gearoil works great too. I used kendal in my NA-T W58 powered, worked great and well known in scooby world! Quote Link to comment Share on other sites More sharing options...

TheTurtleshead Posted March 22, 2012 Share Posted March 22, 2012 Anything 75w/90 in a W58 If you want expensive but quality, millers/valvoline or Motul. If you want cheap buy anything Quote Link to comment Share on other sites More sharing options...

Parry_10 Posted March 23, 2012 Share Posted March 23, 2012 2.6 litres iirc, yes very easy job. Easier if you have something to pump the oil into the box though. Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted March 23, 2012 Share Posted March 23, 2012 (edited) Might as well do diff oil while your at it just get 4 litres of oil that will be enough will be same oil as long as your running the standard manual open diff, make sure you undo the filler plugs before the drain plugs though Edited March 23, 2012 by Parry_10 (see edit history) Quote Link to comment Share on other sites More sharing options...
