{"product_id":"castrol-magnatec-suv-fully-synthetic-5w-40-engine-oil-3-5-lts","title":"Castrol Magnatec Suv  Fully Synthetic 5W-40 Engine Oil 3.5 Lts","description":"Castrol 5W40 Magnatec Suv  Fully Synthetic Engine Oil — 3.5 Lts\r\n\r\nCastrol Magnatec SUV full-synthetic with intelligent molecules formulated for the higher loads and temperatures of larger SUV engines. Engineered for petrol and diesel SUVs and large crossovers.\r\n\r\nViscosity \u0026amp; Temperature: The 5W40 multigrade rating means this oil pumps easily at -35°C for instant cold-start protection and delivers a thick SAE 40 viscosity film at 100°C for high-load engine protection. Combines the cold-flow benefits of a 5W grade with the high-temperature strength of SAE 40 — ideal for engines that run hot under heavy loads or in Indian summer conditions exceeding 45°C. Perfectly suited to India's diverse climate — from cold Himalayan mornings to peak-summer plains temperatures exceeding 45°C.\r\n\r\nUnderstanding 5W40: The first number (5W) is the Winter cold-flow rating — lower means better oil flow at cold start, protecting your engine in the critical first seconds after ignition. The second number (40) is the high-temperature viscosity at 100°C — higher means a thicker, stronger protective film under heat and load.\r\n\r\nPack size: The 3.5 Lts pack is ideal for a partial refill or top-up for high-performance petrol and diesel cars, SUVs, and turbocharged engines. Change oil at your manufacturer's recommended interval — typically every 5,000–10,000 km — to maximise engine life and fuel efficiency.","brand":"ajmeratyres","offers":[{"title":"Default Title","offer_id":45911310663914,"sku":null,"price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/3186\/6090\/files\/Castrol_Magnatec_Suv_Fully_Synthetic_5W40_3.5_Lts.png?v=1773898708","url":"https:\/\/www.ajmeratyres.com\/products\/castrol-magnatec-suv-fully-synthetic-5w-40-engine-oil-3-5-lts","provider":"ajmeratyres","version":"1.0","type":"link"}
