Clive Posted September 26, 2012 Share Posted September 26, 2012 Halfords definitely keep it, as do wilkinsons I believe and most car spares places.You want either EP90 or 80/90 (80 would do at a pinch) BUT it MUST be GL4 specification (not GL5) Quote Link to comment Share on other sites More sharing options...
Hogie Posted September 26, 2012 Share Posted September 26, 2012 Is EP oil really required as the gears in a gearbox (as opposed to a dfiff) are not EP types.Don;t know anything about Spitfires and what TRiumph suggest but surely a normal gear oil is what should be used.I shall now duck below the parapet.Roger Quote Link to comment Share on other sites More sharing options...
Clive Posted September 26, 2012 Share Posted September 26, 2012 Tis what triumph specified. That is good enough for me :) Quote Link to comment Share on other sites More sharing options...

dazasdolly Posted September 26, 2012 Share Posted September 26, 2012 I just replaced my gearbox fluid with what Clive has said ;) Quote Link to comment Share on other sites More sharing options...
Hogie Posted September 26, 2012 Share Posted September 26, 2012 Hi Folks, enough said, go by the book. A small benefit of the thicker oil is it doesn't escape so readily.Roger Quote Link to comment Share on other sites More sharing options...

Dextron or similar will leak...well everywere on a 60's gearbox. Quote Link to comment Share on other sites More sharing options...

Dextron or similar will leak...well everywere on a 60's gearbox.Normal gear oil - non EP. Gearbox gears are designed not to act in an EP mode - the lobes roll over each other as opposed to sliding.You could still use an 80 or 90 grade but without the EP additives. Just my view.I know in the early days that EP was frowned on if there was an O/D fitted to the G/B - some concern that the EP additives break down and bung up the O/D oilways.More modern EP's are more stable. However having said all that you could probably run most Triumph stuff on cooking fat and get away with it.Roger Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 27, 2012 Share Posted September 27, 2012 the gearbox on the small chassis cars was a development from the likes of the standard 8, its the weakest link in the end of design life and fatigue failures on our cars, reduce the oil specification at your peril Pete Quote Link to comment Share on other sites More sharing options...
