Engineered for petrol and diesel passenger cars requiring all-day engine protection.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003eViscosity \u0026amp; Temperature: The 10w40 multigrade rating means this oil maintains pumpability from -25°C and provides a heavier SAE 40 film at 100°C for more demanding engines. The SAE 40 high-temperature rating makes it ideal for older or high-mileage engines that benefit from a thicker oil film to compensate for increased internal clearances. Perfectly suited to India's diverse climate — from cold Himalayan mornings to peak-summer plains temperatures exceeding 45°C.\u003c\/p\u003e\n\u003cp\u003eUnderstanding 10w40: The first number (10W) 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.\u003c\/p\u003e\n\u003cp\u003ePack size: The 3 Lts pack is ideal for a partial refill or top-up for older petrol and diesel engines, motorcycles, and high-mileage vehicles. Change oil at your manufacturer's recommended interval — typically every 5,000–10,000 km — to maximise engine life and fuel efficiency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShop with confidence at Ajmera Tyres\u003c\/strong\u003e — genuine products, expert advice, and fast delivery across Nagpur, Pune, and Amravati.\u003c\/p\u003e","brand":"ajmeratyres","offers":[{"title":"Default Title","offer_id":45911312236778,"sku":null,"price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/3186\/6090\/files\/Castrol_Magnetec_10w40_3_Lts.png?v=1773898716","url":"https:\/\/www.ajmeratyres.com\/products\/castrol-magnetec-10w-40-engine-oil-3-lts","provider":"ajmeratyres","version":"1.0","type":"link"}
