Free Shipping

Decor Outdoor offers free regular shipping on all orders shipped to residential or commercial addresses within the contiguous United States. Orders are delivered Monday through Friday (excluding holidays).

Drop Shipping

We are an online-only luxury furniture and lighting boutique, and do not have a warehouse. Consequently, all orders are drop shipped directly from our manufacturers to your door. If your order includes items from more than one manufacturer, you will receive multiple deliveries. Because we are dependent on the on-hand inventory of our manufacturing partners, some items listed on our site may not actually be available right away. Please call us at 888.784.4644 or via our contact form with any stocking questions and we'll get in touch with the appropriate manufacturer for answers, before you place your order.

Ground Shipping

Small parcel items ship regular ground via delivery services such as FedEx, UPS or DHL. Orders typically take 2-3 business days to process and in-stock items will usually be delivered 3-5 days from the date that they ship (depending on origin and destination). If there is a delay, you will be notified by email. No signature is required for standard ground shipping, so you may want to make arrangements to have packages brought inside soon after delivery, if you are unable to receive it in person.

We speak a lot about the importance of gut health—not only for beauty—but also in terms of our overall health, wellbeing and immunity. But before we can fully understand why the gut is so integral to our health, it’s first essential to learn more about the physiology of the gut itself—and how it works.

Description

Mobil Delvac MX™ 15W-40 is an extra high performance diesel engine oil that provides excellent lubrication of today’s diesel engines promoting extended engine life. As a result, this product meets or exceeds the specifications of virtually all major European and American engine manufacturers. This extra high performance has been proven in the field in a wide variety of industries, applications, and mixed fleets.

The advanced chemistry of this product provides outstanding performance in both modern, demanding low-emission diesel engines and older diesel engines operating on low or high sulphur fuel. Mobil Delvac MX 15W-40 combines a blend of high performance base stocks with a progressive additive system to provide superior control of oil thickening due to soot build-up and high temperatures as well as outstanding resistance to oxidation, corrosion, and high temperature deposits.

Features and Benefits

High output, low emission diesel engines significantly increase the demands on engine lubricants. Tighter engine designs reduce oil consumption, resulting in less fresh oil make-up to replenish depleted additives. Top piston fire rings are located higher on the piston bringing the oil film closer to the combustion chamber where higher temperatures increase thermal stress on the lubricant. Increased fuel injector pressure and retarded timing improve fuel burn efficiency, but also increase engine temperatures and increase soot loads. Mobil Delvac MX 15W-40 is formulated from high performance base oils and a superior balanced additive system to provide optimum engine performance in modern diesel and gasoline engines as well as older models. The key benefits include:

Features Advantages and Potential Benefits
High thermal and oxidation stability Reduced sludge build-up, deposits and viscosity increases
TBN reserves Deposit control and acid neutralisation
Stay-in-grade shear stability Wear protection and viscosity control
Advanced detergency/dispersancy Cleaner engines and longer component life
