tuko Posted January 16, 2015 Share Posted January 16, 2015 In both our our 300Tdi's I run only 15w/40 mineral oil, changing it once a year. Quote Link to comment Share on other sites More sharing options...
teabag Posted January 16, 2015 Share Posted January 16, 2015 What oil does "everyone" use ? All the info on grades and spec is in the disco owners handbook and it's all multi grade, it's up to you to choose. Quote Link to comment Share on other sites More sharing options...
Boydie Posted January 16, 2015 Share Posted January 16, 2015 For what it's worth, using a fully or part synthetic in a diesel engine is an exercise in extravagance - just use a good mineral oil (Caltex, Mobil, et al) and change it every 10,000 kilometres along with fuel and oil filter.
