bekker 7 Report post Posted March 30, 2007 Penrite. They do both mineral and synthetics. They stack up very well against the likes of Redline, Amsoil etc and are fantastic value for money. BTW, they do a fully synthetic 15w40 engine oil which is very well suited to a lot of BMW's. Cheers Quote Share this post Link to post Share on other sites
