Shipping Information

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 Legend 1640 is extra high-performance diesel engine oils formulated from advanced base oil and a balanced additive system to meet or exceed the demanding specifications of the world’s leading builders of modern diesel engines. It is recommended by ExxonMobil for use in European and Japanese-designed intercooled, highly turbocharged engines operating under the most severe on and off-highway conditions.

Features and Benefits

Today’s low emission engines place increasing demands on engine lubricants. Tighter engine designs reduce oil consumption, resulting in less fresh oil make-up to replenish depleted additives. Higher piston top ring positioning brings the oil film closer to the extreme combustion temperatures increasing thermal stress on the lubricant. Higher fuel injection pressure and retarded timing improve burn efficiency, but also increase engine part loading, temperatures, and soot in the oil. The advanced technology in Mobil Delvac Legend 1640 provides exceptional performance in both modern diesel engines as well as older models. The key benefits include:

Features Advantages and Potential Benefits
 

 

 

Outstanding protection against oil thickening, high temperature deposits, sludge build-up, and oil degradation

Outstanding control of high temperature deposits

 

 

Extended oil life above OEM recommended Oil Drain Intervals(ODI)

 

Excellent protection against ring sticking

Exceptional wear protection Reduces maintenance costs and extends engine life
Excellent soot handling capabilities Maintains viscosity control and reduces wear
