A 12 TBN is relatively high for a 15W-40 diesel oil, which makes AME1GC a strong choice for engines that generate significant combustion blow-by or run EGR systems that increase acid load on the oil.\u003c\/dd\u003e\n\n  \u003cdt\u003eWhat is the difference between AME1GC and AMEQTC?\u003c\/dt\u003e\n  \u003cdd\u003eSame formulation — same oil, same viscosity, same API rating.

The high TBN and synthetic formulation make it a step up from conventional heavy-duty diesel oils in the same viscosity class, particularly for engines running extended hours between service, or in boats that see infrequent seasonal use where oil degradation matters. It’s also a cost-effective option for customers who want a premium synthetic at a lower price than OEM-branded lubricants.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon customer questions:\u003c\/strong\u003e The most frequent issue is customers assuming any 15W-40 diesel oil will work in their engine, including modern DPF-equipped engines. Always confirm the engine’s required API category before completing the order — AME1GC is a CI-4+ oil, not a CJ-4 or CK-4 low-SAPS oil. The second common question is about drain intervals — customers ask if they can run it longer than the OEM interval. The answer is “only with oil analysis or explicit AMSOIL guidance for their application”, not simply because it’s synthetic. Also confirm the correct filter for their engine if they are ordering oil and filter together.\u003c\/p\u003e","brand":"FVW","offers":[{"title":"Default Title","offer_id":43563794989092,"sku":"ame1gc","price":362.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_45c73ded-2360-4225-aad9-c934c2de54f2.jpg?v=1788742424"},{"product_id":"honda-marine-10w-30-nmma-oil-08207-10w30fcw","title":"Honda - Marine 10W-30 NMMA Oil - 08207-10W30FCW","description":"\u003cp\u003e\u003cstrong\u003eHonda Marine 10W-30 FC-W Engine Oil\u003c\/strong\u003e is formulated for Honda marine engines and approved to meet the \u003cstrong\u003eNMMA FC-W\u003c\/strong\u003e marine oil standard.

The cost-per-litre advantage over the 4L bottle adds up quickly if you’re running a high-hour OptiMax season. The key thing to nail before ordering: confirm your engine’s reservoir calls for “OptiMax Oil” or “DFI Oil” — if it does, this is your product. If the reservoir or manual says Premium or TC-W3, that’s a different oil. Running standard TC-W3 in a DFI system can cause carbon buildup in the injection components over time, which is one of the more avoidable service headaches we see on these engines.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563885625380,"sku":"858038KC1","price":191.28,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/84b0e2ad-29ff-40b6-84d4-140cba8210f6.png?v=1789442254"},{"product_id":"mercury-quicksilver-gear-lube-858058kc1","title":"Mercury Quicksilver High Performance Gear Lube – 858058KC1","description":"\u003cdiv class=\"flex flex-col text-sm pb-25\"\u003e\n\u003csection class=\"text-token-text-primary w-full focus:outline-none [--shadow-height:45px] has-data-writing-block:pointer-events-none has-data-writing-block:-mt-(--shadow-height) has-data-writing-block:pt-(--shadow-height) [\u0026amp;:has([data-writing-block])\u0026gt;*]:pointer-events-auto scroll-mt-[calc(var(--header-height)+min(200px,max(70px,20svh)))]\" dir=\"auto\" data-turn-id=\"request-WEB:cd752dab-2ca2-48b9-a8be-3a6513ba9f84-119\" data-testid=\"conversation-turn-18\" data-scroll-anchor=\"true\" data-turn=\"assistant\"\u003e\n\u003cdiv class=\"text-base my-auto mx-auto pb-10 [--thread-content-margin:var(--thread-content-margin-xs,calc(var(--spacing)*4))] @w-sm\/main:[--thread-content-margin:var(--thread-content-margin-sm,calc(var(--spacing)*6))] @w-lg\/main:[--thread-content-margin:var(--thread-content-margin-lg,calc(var(--spacing)*16))] px-(--thread-content-margin)\"\u003e\n\u003cdiv class=\"[--thread-content-max-width:40rem] @w-lg\/main:[--thread-content-max-width:48rem] mx-auto max-w-(--thread-content-max-width) flex-1 group\/turn-messages focus-visible:outline-hidden relative flex w-full min-w-0 flex-col agent-turn\"\u003e\n\u003cdiv class=\"flex max-w-full flex-col gap-4 grow\"\u003e\n\u003cdiv data-message-author-role=\"assistant\" data-message-id=\"ca7138da-460b-4f0c-b663-465ce7b43ce5\" dir=\"auto\" data-message-model-slug=\"gpt-5-4-thinking\" class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal outline-none keyboard-focused:focus-ring [.text-message+\u0026amp;]:mt-1\" data-turn-start-message=\"true\" tabindex=\"0\"\u003e\n\u003cdiv class=\"flex w-full flex-col gap-1 empty:hidden\"\u003e\n\u003cdiv class=\"markdown prose dark:prose-invert w-full wrap-break-word dark markdown-new-styling\"\u003e\n\u003cp data-start=\"80\" data-end=\"577\"\u003eMercury Quicksilver High Performance Gear Lube 858058KC1 is a marine gearcase lubricant formulated for \u003cstrong data-start=\"209\" data-end=\"248\"\u003eoutboard and sterndrive lower units\u003c\/strong\u003e.
