It is specifically developed for applications in long haul trucks, b double road trains, and other severe duty operational environments. This formulation ensures optimal performance and protection under demanding conditions.\n\nThis lubricant is approved against Volvo's stringent Heavy Duty Manual Transmission specification 97319. This approval enables extended oil drain intervals, up to 400,000 kilometers (248,000 miles), in severe duty manual and automated manual (i-Shift) transmission applications. It also demonstrates proven synchronizer performance, facilitating easier gear changes, quieter transmission operation, and a reduction in driver fatigue. Furthermore, its excellent low-temperature fluidity ensures easy gear shifting during cold starts, and its excellent wear protection extends gear life.\n\nCastrol Syntrans Heavy Duty 75W-90 is also suitable for use in the manual transmissions of cars or light commercial vehicles where GL-4 oils are recommended. Its excellent oxidation stability ensures suitability in high-temperature applications and supports extended drain intervals. The long drain performance offers the potential to lower maintenance costs and increase vehicle availability.","brand":"Castrol","offers":[{"title":"Default Title","offer_id":52687352004920,"sku":"15E7A1","price":403.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660191719.webp?v=1784883124","url":"https:\/\/store.motormia.co\/products\/syntrans-heavy-duty-75w-90-manual-transmission-lubricant","provider":"MOTORMIA","version":"1.0","type":"link"}
