That’s about $12~$15 a litre compared to ZF $26 per litre. As high as $60 @ litre at some places!!!!If you don’t have access to the Castrol Lubrication/Application Guide then you should find one at your local car parts shop like AutoBarn etc. Must be the latest edition!!!Enjoy Link to comment Share on other sites More sharing options...

I run @ 350rwks so its working its ring off.I know at my rwkws it wont do 15,000 ..no way infact 5,000 at that hp might just make it if I drive hard. so the Castrol Reps recomendations is probably close.

Problem is the hard cover won't close hahahahahhahaGetting the 8 litres out especially the converter is a worry and I hate mixing oils so I might do one change to Z and then do a 100k's and do it again. Mmmmm Still way cheaper than 1 oil change with ZF oil. Link to comment Share on other sites More sharing options...
