davej Posted July 3, 2013 Report Share Posted July 3, 2013 Hi does anyone know if it would be ok to top up my gearbox oil with 75w-90 Semi synthetic GL 5. I have a sdi -1.7 and have just changed the gearshift oil seal. Thanks dave Quote Link to comment Share on other sites More sharing options...
sixteenvalve1400 Posted July 3, 2013 Report Share Posted July 3, 2013 We used 75-90 synthetic gear oil in our Lupo I was told it is ok to use. synthetic, semi synthetic or mineral oils as long as they are not mixed together in use. Quote Link to comment Share on other sites More sharing options...
