cooperman Posted June 9, 2011 Report Share Posted June 9, 2011 i think you need 5w30 for the gen 7 definately fully synthetic. and yes the castrol is good stuff. andy Link to comment Share on other sites More sharing options...

planc Posted June 9, 2011 Report Share Posted June 9, 2011 A bit late but 5w30 semi is best recomendation for the 140. Link to comment Share on other sites More sharing options...
