Shell has introduced the first transformer oil in the market that is based on the new Shell GTL (gas-to-liquids) technology. The Shell Diala S4 ZX-I is essentially sulfur-free and, compared to traditional mineral-oil-based products, offers exceptional performance and long-term stability, even under high pressure. Shell Diala S4 ZX-I is manufactured from pure GTL base oil, which is essentially sulfur-free.
