Koçak Speedol, Turkish lubricant and grease manufacturer makes a mark with the first domestic turbodiesel engine oil approved by TEI, Speedol Aero Ultra Diesel S170. With its competent R&D team, accredited laboratory, and high-tech machine park, the company strengthens the local defence and aviation industry by domestic production of the major import item.
Türkiye continues to make domestic and international investments in aviation and defence, and this leap is reflected throughout the industry. While the airplanes, helicopters, and unmanned aerial vehicle projects of Turkish Aerospace Industries (TUSAŞ) are a source of pride for Türkiye, they also present companies from various industries with chances for growth and development.
One of the best examples of this development is Koçak Speedol, Turkish lubricant and grease manufacturer. Adding value to the lubricant sector through its competent R&D team, accredited laboratory, and high-tech machine park, Koçak Speedol creates a difference in the defence and aviation industries.
The company produces Speedol Aero Ultra Diesel S170, the first domestic turbodiesel engine oil approved by TEI (TUSAŞ Engine Industries, INC). The product which fulfills the engine oil needs of TUSAŞ ANKA, the unmanned aerial vehicle (UAV) developed in accordance with the needs of the Turkish Armed Forces, meets the demand in the major import item through domestic production. Products under the Speedol brand are listed first among engine and transmission oils in the Aircraft Maintenance Manual (AMM) of the turbodiesel engine.
Approved Product
Speedol Aero Ultra Diesel S170 became the first TEI-approved turbodiesel engine oil. TRtest also certified that the product meets ACEA, SAE, and ASTM standards in accordance with TEI-PD170 engine specifications. Thus, the synthetic aviation oil Speedol Aero Ultra Diesel S170 became the first domestic and national engine oil in its category to be awarded the TRtest Product Conformity Certificate.
