Next-Generation Oils and Engines Allow Longer Drain Intervals

by on January 13, 2017 14 Comments

DeloTruck_Blog_011217With the launch of the new API CK-4 and FA-4 heavy duty engine oils, many OEMs are now allowing an extension of oil drain intervals when these products are used in their newer engines. This is big news for on-highway fleet operators. Chevron has just published a comprehensive guide to North American Truck OEM recommended drain intervals, detailing all the major manufacturers’ recommendations by engine type based on the new oil categories.

Just how significant are these oil drain interval extensions? Among all the leading manufacturers, we are looking at double-digit percentage increases in mileage between drains for newer engines: for Volvo, around 20%; for Paccar, 25%; and for Daimler, as much as 50% in long-haul applications.*  Certainly, fewer oil changes every year means a big expense reduction for fleets.

Improved Oxidation Stability is Key

To be clear, it is not just the advancement in oil formulation that is making these extended intervals possible. The newer engine designs produce less soot, meaning less contamination in the oil, which can help extend oil life. However, improved oil oxidation resistance and wear performance with the new oil categories are the main factors in helping to allow for extended oil drain intervals, while still maintaining engine component durability. Providing improved oil oxidation performance was a key priority in the development of API CK-4 and FA-4 oil categories.  Our new Delo 400 oils show up to a 35% improvement in oil oxidation control compared to the prior generation of heavy duty motor oils in engine qualification testing.

Engine manufacturers, truck builders and lubricant suppliers have been working together to improve total vehicle efficiency as part of the evolving Greenhouse Gas Regulations. This collaborative effort has led to improved GHG ‘17 diesel engine models and lower viscosity heavy duty engine oils that help maximize fuel economy performance, reduce CO2 emissions, and support improved engine reliability and protection. When these improvements are extended across an entire fleet they help reduce maintenance costs, keep trucks on the road longer and dramatically improve ROI.

    Why is 1030 and 5w40 full synthetic going to help increase miles per gallonwhat oil will incrrsse miles on a land fill operation

    •' Leonard Badal says:

      Hi Bill, thank you for your questions! Allow me to break down your two questions below:

      -Why is 1030 and 5w40 full synthetic going to help increase miles per gallon-

      This is a good question. The lower viscosity oils will provide improved flow at start-up which reduces friction of your moving engine parts, which in turn reduces your engine’s need to overcome this resistance and helps save fuel. Additionally, when running on the road, lower viscosity oils have less fluid resistance because they are thinner which again reduces your engines need to overcome the friction- saving fuel.

      -What oil will increase miles on a land fill operation.-

      Typically, we would need to know your operation and engine type to fully answer your question and provide appropriate engine oil recommendation – but assuming these items were known and not an issue – we would recommend using our Delo 400 XLE SAE 10W-30 in your operation. We have fully tested this product in both on-highway trucks and also off-road construction and mining equipment with great success – we have found customers who have made the switch have even seen a reduction in wear versus 15W-40 engine oils due to the improved startup performance.

    Have customers in off road and over the road mid and heavy duty

    •' Leonard Badal says:

      Delo 400 XLE SAE 10W-30 is a great option for these customers – if they do operate significantly older engines or have sever load or gradient (uphill hauling) operations our Delo 400 XLE SAE 15W-40 and Delo 400 SDE SAE 15W-40 are great options also, but they won’t provide fuel economy performance.

    In our family we have a Ford F-350 with a 7.3 with 125,000 miles , another with a 6.0 with 205,000 miles and another with a 6.4 with 102,000 miles. Also, a Dodge Dakota with 100,000 plus with a gas engine. What weight of oil should we be using? All pickups are used to pull moderate loads.
    Also, older IH farm tractors two with the German diesels which I am thinking that these are 310 engines, an 826 and a 706; along with two IH Super MTA’s gas engines. Where can we find your product in northwest Iowa?

    •' Leonard Badal says:

      Gayle, thanks for the great question and appreciate your interest/loyalty to the Delo brand. Based on what you have provided for the different pick-up trucks and German engines – Delo 400 LE SAE 15W-40 or Delo 400 SDE SAE 15W-40 would be great candidates for you to use across all the engines. Delo 400 SDE 15W-40 was just recently launched so my be initially harder to find now as a number of retailers and our distributors are starting to bring in inventory, but Delo 400 LE 15W-40 is great and when you can find the new delo 400 SDE 15W-40 move to it since it will provide an excellent increase in wear protection and resistance to oil sludge build up – even beyond our very good Delo 400 LE product.

      In regards to the question about where Delo products can be found in Northwest Iowa, this retailer’s link should be a useful resources to help out:

      Let us know if you have any other questions.

  4.' Greg Batten says:

    What do the SDE, XLE and LE letter stand for?

    •' Leonard Badal says:

      Hi Greg, SDE stands for Severe Duty Extend; XLE stands for Xceptional Lubricant Efficiency and LE stands for Low Emissions.

  5.' JERRY JUDY says:

    i would like more information about your 400 XSP 5w-40 so I can use it in my 2008 chev. silverado duramax 6.6. The milage is 90,000 and I have been using Delo 400 LE 5w-40 Full Synthetic. Please help me locate this product before mid 2017.

    • Shawn Whitacre says:

      HI Jerry, stay tuned. We have not yet launched Delo 400 XSP SAE 5W-40. In the meantime, Delo 400 LE Synthetic SAE 5W-40 remains available to service your Silverado.

  6.' Leroy says:

    Have a 2014 Mack with a MP8. Currently using delo 15-40. I do 5 axle long haul work anywhere from Florida to Alaska. Should I be going with 5-30 or 10-30 oil

  7.' Carlo Ribera Sr. says:

    Leonard, my name is Carlo I am with Port Consolidated in Miami marketer for Chevron. Can you talk about Chevron Ursa for OTR applications on Cummins ISK engines. Customer is complaining of low oil pressure with less than 100 mile on these engines. Yet we use 5gl pails and no issues. We know if being packaged by our facility from Bulk. Any ideas ?

    • Shawn Whitacre says:

      Hi Carlo, thanks for your inquiry. In this case, it is probably best that you reach out to one of our Technical Experts at 1-800-LUBE-TEK (800-582-3835) for follow-up on this matter.
