Tough Service Oil Introduced

Tough Service Oil Introduced

Chevron to launch Delo 400 SD 15W-30 into both on- and off-highway severe service markets.

The changing nature of engines and engine technology, combined new ways to put those power plants to work is stressing the lubricants those machines depend on for survival. From high-temperature spikes from turbocharger oil flow to stop-and-go operation that causes cooling issues and boosts  severe service requirements - operators are stressing the lubes they use in their best machines.

Chevron is stepping into this changing market with a new product that offers higher viscosity and improved durability in tough applications. The new product is designed to compete in what Chevron calls the XW-30 market where that 'X' is usually a '10' as oil viscosity drops.

"This is not a one oil fits all world," says Randy Brillhart, general marketing manager, Chevron. The answer is to target oils for specific service areas and meet specific challenges for users.

Changing oil challenge

In the off-highway market, Jim Gambill, Delo Brand Manager, explains, that machinery is being used in more "load/no-load" situations where the machine runs at constant rpm but the machine senses when it's not under load and changes operation until put back under load.

It's those kinds of situations that can stress a lubricant as engine temperatures can spike quickly an drop back just as fast. Temperature changes, and high-temperatures situations, can wear down engine oils, but the new Delo 400D product is designed to work in those more severe duty situations.

Chevron sponsored research at the Southwest Research Institute, which does a lot of engine research, to look at how engine temperatures change during operation. More specifically, they looked at what happens when you turn an on-road engine off. "During engine shut-off the oil return from the turbo can rise 25 degrees F," says John Green, product technical support specialist. That temp spike can rise as high as 67 degrees F just a few minutes after shutdown, he adds.

That's an on-road example, but shows what users are asking of oil these days. "Oil has to cope with those higher temperatures and that can increase oxidation," Green adds.

And farmers may find they're putting other diesels in their operations under severe service conditions without thinking about it. During a webinar detailing the new product, Green showed a light-duty diesel pickup pulling a stock trailer. That's a common sight in the country, and one where that diesel engine is sometimes stressed pretty hard. That can oxidize oil faster as well.

In tests conducted by Southwest Research Institute, the new Delo 400 SD actually out-performed two competitive synthetic oils and two synthetic oil blends. In the test, oil is heated to 210 degrees C until it produces what is called an "exothermic" peak. The new 15W-30 lasted longer before oxidizing that a range oils - including two competitive conventional oils.

Trust but verify

Whenever a company brings out a new product there are questions and Chevron is working to answer them. In fact, purchase just 10 gallons of the new product - about what you need for a heavy duty pickup oil change, and you're eligible for five free oil analyses. "This is to provide the user the proof they need that the product performs," says Brillhart.

It's also a great way to determine the right engine oil change interval for your specific application based on what's actually happening in the engine as well. You would go online to register to get those tests sent your way once you provide proof of purchase of the 10 gallons.

The new product - Delo SD SAE 15W-30 is designed for use in on- and off-highway engines including 2010 compliant engines using ultra-low sulfur diesel. And the oil is designed to "meet the most stringent [exhaust gas recirculation] soot control and particulate requirements," according to the company.

Chevron is recommending that users follow original equipment manufacturer change intervals, this product is not being released for use as a way to extend service intervals. Instead it's designed to provide enhanced engine protection over competitive oils in severe service situations.
