Thailand’s PTT Oil and Retail (PTT) was the country’s largest lube supplier in September for a seventh straight month.

The company’s rising share of lube demand in the first nine months of the year also cushioned the impact of a sharp slowdown in the country’s total consumption during most of that period.

Thailand’s lube consumption of 40,000 kilolitres (35,400 tonnes) in September rose from year-earlier levels for the first time in seven months.

PTT accounted for a 35% share of the total volume. The share rebounded from less 29% in July and in August amid a pick-up in sales of industrial oils.

Shell Company of Thailand was the country’s second-largest supplier in September even as its 20% share of lube demand fell from 25% in August.

PSP Specialties, Thailand’s largest independent lubricants manufacturer, was the third-largest supplier in September with a share of around 18% of the total.

Its share of consumption had held above 20% of the total in each of the previous five months to August.
