The 5W-40 grade is particularly well-suited for year-round use in climates with cold winters, as it flows faster at startup than a straight 15W-40. If your engine spec calls for a 5W-40 or CJ-4\/CK-4 rated oil, this is a strong fit. For engines requiring a straight-weight or 15W-40, see the Rotella T4 or T1 options in our lineup.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199661277220,"sku":"852-550045390","price":62.39,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/852-550045390.jpg?v=1785611269","url":"https:\/\/marisolmarine.com\/products\/rotella-t6-synthetic-heavy-duty-engine-oil-5w40-5-liters-852-550045390","provider":"Marisol Marine Company","version":"1.0","type":"link"}
