Jgaskell3 0 Posted August 15, 2013 Swapping oil is fine as long as u dont swap from castor to synthetic or vice versa. Thanks Paul The silkolene says castor and synthetic and speedway blue says castor with additives will it be ok to use the silkolene? Cheers John Share this post Link to post Share on other sites
paul90210 40 Posted August 19, 2013 The oil will be either synthetic or castor, not both. Once u find out which one it is u can mix different brands as long as u dont swap between synthetic and castor until u have an engine service Share this post Link to post Share on other sites
