I haven't dealt with Castrol for a few years now, but I think they now have RX Super, a RX Super plus. RX is CI-4 and plus is CI-4 plus. I think. without jumping on their website.

Yeah so there is rx super which I bought with ci comes in white bucket. Then RX diesel black bucket n RX super super I think, which I think is like modern diesels
Yeah seems like so many these days, looks like I’ll be running Castrol forever 👌 decently priced too
Yeah definately is, I paid around $90 for 20L.
I very well could be wrong.
I thought RX was mineral and RX Super was semi-synthetic like Delo 400.
I personally run Delo 400 last few services ... But it's getting hard to find so may have to go with Rx super .

Nah still mineral Eric, same as Delo400. Just a mineral oil, Nothing wrong with that though... Where I used to work in Campbellfield mate I think they sell the Premium variant for around $110. If your keen let me know and I'll set it up. I may even get some for myself too but oil changes are few and far between these these.
