{"product_id":"castrol-mag-stop-start-5w-30-engine-oil-3-lts","title":"Castrol MAG STOP START 5W-30 Engine Oil 3 Lts","description":"Castrol 5W30 MAG STOP START Engine Oil — 3 Lts\r\n\r\nCastrol Magnatec Stop-Start with Dualock molecules that bond to engine parts and reduce the 60% extra wear caused by frequent stop-start restarts. Engineered for modern petrol and diesel cars with idle stop-start systems.\r\n\r\nViscosity \u0026amp; Temperature: The 5W30 multigrade rating means this oil flows freely at -35°C for fast cold-start protection and maintains SAE 30 viscosity at 100°C engine operating temperature. The low 5W cold-pour rating ensures quick oil circulation on startup while the SAE 30 high-temperature grade provides a robust lubricating film during sustained highway driving. Perfectly suited to India's diverse climate — from cold Himalayan mornings to peak-summer plains temperatures exceeding 45°C.\r\n\r\nUnderstanding 5W30: 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 (30) 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 Lts pack is ideal for a partial refill or top-up for modern petrol and diesel passenger cars, especially stop-start 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":45911306109162,"sku":null,"price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/3186\/6090\/files\/Castrol_MAG_STOP_START_5W30_3_Lts.png?v=1773898689","url":"https:\/\/www.ajmeratyres.com\/products\/castrol-mag-stop-start-5w-30-engine-oil-3-lts","provider":"ajmeratyres","version":"1.0","type":"link"}
