Castrol have stopped making Hypoy LS apparently and there's now a product called Castrol SAF-XJ SAE 75w-140 Fully Synthetic Hypoid Gear Oil
First of all, is this a suitable oil for a 1988 +8 differential?
Secondly, noting it's synthetic, will it still need the magic little bottle of Jaguar additive?
What other manufacturers' products are preferred today for this final annual crawl-under Spring rite?
Thanks for all ideas/comments
