It says for older engines but is it suitable for diesels rather than just petrols - also apparently it's low detergent if that's a good thing or not? We don't use oil at all - rarely top up a drop in a season and have very good compression and oil pressure. So I'm wary of using an oil designed for engines that do have those problems. Or am I over thinking this? Again![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
