a98pmalcolm 0 Posted October 29, 2007 Hay people. Just had my engine rebuilt by The Engine Shop. Its G60 engine Bored to a 1.9 and in the leaflet with the engine it only says to use NON Synthetic Oil for the running in period but it didnt say what grade. So what do u guys think? Thanks Paul Quote Share this post Link to post Share on other sites
Lizard Racing 0 Posted October 29, 2007 Basic 10W40 mineral oil, I use Castrol GTX. If you can get hold of it Millers do a running in oil. Quote Share this post Link to post Share on other sites
