PETRONAS' superior quality group III base oil is marketed under the ETRO brand name. The combination of over 130 VI and low Noack makes ETRO one of the highest quality group III base oils in the market. Given that ETRO is produced exclusively from PETRONAS crude, both feedstock supply and product consistency are assured. Moreover, sales and delivery to worldwide destinations are streamlined by direct distribution through the end-to-end supply chain network of PETRONAS Base Oil (M) Sdn Bhd while PETRONAS Marketing Netherlands B.V. was established especially to cater for the European market. This, combined with the company's industry-leading technical and logistics capabilities further assures a reliable supply source. PRODUCT DESCRIPTION ETRO 4 and ETRO 6 are very high quality Group III base oils manufactured from a proprietary wax isomerisation process and hydrofinished to a colourless liquid. These base oils are highly isoparaffinic and exhibit high viscosity index values, as well as superior low temperature performance. Both have excellent viscosity-volatility relationship.
