{"product_id":"castrol-active-4-t-20w-40-engine-oil-900-ml","title":"Castrol Active 4 T 20W-40 Engine Oil 900 ML","description":"Castrol 20W40 Active 4 T Engine Oil — 900 ML\r\n\r\nCastrol Active 4T motorcycle engine oil with ActiGrip technology for superior wet clutch performance, gear protection, and engine cleanliness. Engineered for four-stroke motorcycles and scooters for everyday Indian commuting.\r\n\r\nViscosity \u0026amp; Temperature: The 20W40 multigrade rating means this oil suitable for ambient temperatures above 0°C, common across India's plains and maintains SAE 40 viscosity at 100°C for solid engine protection. Designed for warmer climates — the 20W cold grade matches India's year-round temperatures perfectly, and the SAE 40 hot grade provides a solid lubricating film for two-wheeler and older car engines. Perfectly suited to India's diverse climate — from cold Himalayan mornings to peak-summer plains temperatures exceeding 45°C.\r\n\r\nUnderstanding 20W40: The first number (20W) 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 900 ML pack is a handy top-up size for routine level checks or emergency use. 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":45911290609898,"sku":null,"price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/3186\/6090\/files\/castrol_active4T_20W40.png?v=1773898612","url":"https:\/\/www.ajmeratyres.com\/products\/castrol-active-4-t-20w-40-engine-oil-900-ml","provider":"ajmeratyres","version":"1.0","type":"link"}
