Dear Valued Customer

Chevron recently announced they will be making updates to the Delo 400 heavy duty engine oil product line with the goal of stabilizing product reliability and pricing.

Planned changes include moving from four categories of engine oils to two – a line of synthetic blends and a line of fully synthetic options – making it easier for you to get the highest quality range of HDEO you’ve come to expect from Chevron.

Beginning in January 2024, Chevron will discontinue its conventional products, Delo 400 SDE 10W-30/15W-40 as well as Delo 400 XLE 15W-40. Chevron will introduce a new synthetic blend, Delo 400 XLE SB 15W-40, to replace the Delo 400 SDE and XLE 15W-40 products that you are using now – with absolutely no compromise.

We will be in touch with you to discuss future orders of Delo 400 products. Attached is the Delo 400 XLE SB 15W-40 product flyer that outlines features and benefits, as well as the list of OEM approvals. Please call if you have any immediate questions.

We sincerely thank you for your patronage and loyalty and look forward to working together throughout the year!

Start the year with the extra protection of premium Chevron Delo Coolants!

(Read more HERE about why proper coolant maintenance is so important)

While engine coolant maintenance is just as important as an oil change, the coolant system is one of the most overlooked preventive maintenance items in a diesel engine, with 40% of engine failures attributed to cooling system issues.

Premium Delo Coolants are formulated with patented technology that helps protect modern cooling systems and prevent costly repairs and unplanned downtime. 

Chevron Delo® XLC Antifreeze/Coolant is an extended-life anti-freeze that provides protection in all the elements, winter to summer. It is well-suited to both heavy- and light-duty trucks and equipment, as well as RVs and boats. The silicate-free formula reduces wear on water pumps and offers excellent protection against pitting, corrosion, and erosion even on hard-to-protect metals like aluminum. Chevron Delo® XLC Antifreeze/Coolant has a service life of 1,000,000 miles / 1,600,000 km / 15,000 hours, or 8 years, or 1,200,000 miles / 1,900,000 km / 20,000 hours or 8 years of diesel engine coolant system protection when properly maintained with a Chevron Delo® FleetFix® CMX addition at 600,000 miles / 960,000 km / 10,000 hours or 4 years 1.

Delo ELC Antifreeze/Coolant products are heavy-duty engine coolants that use a patented organic corrosion inhibitor technology called aliphatic carboxylates. Delo ELC is free of nitrates, borates, silicates, phosphates, and amines. These products contain nitrites and molybdates for additional cylinder liner protection.

Chevron is offering a rebate promotion for agriculture customers prior to planting season. From February 1 – April 30, 2024, those who purchase qualifying Chevron Delo® products can claim a rebate of up to $3.00 per gallon. The rebate claim deadline is May 15, 2024.

The Customer Rebate Offer is a “Buy More, Get More” promotion. If your business buys one qualifying product, you will receive a $1.00/gallon cash rebate. If you buy two qualifying products, you will receive a $2.00/gallon cash rebate, and so on. The minimum total gallons required to qualify for the rebate is 55 gallons.

Let’s Dispel Some Common Misconceptions About Fluid Analysis

Fluid analysis diagrams the health of your equipment

At Chevron, we are strong advocates of regularly scheduled, in-service fluid analysis for both on-highway and off-highway equipment. We have seen first-hand how it can help fleets identify potential issues to avoid costly unscheduled equipment repairs and downtime. Yet we still hear some skepticism about the value of fluid analysis from fleet operators who question whether it’s worth the time, effort and expense. So, let’s look at some of the common misconceptions about fluid analysis, as well as the benefits of a systematic well executed fluid analysis program.


Why not just change the oil? The equipment is scheduled for maintenance anyway.


If you’re having a problem with the equipment, changing the oil may correct it. However, fluid analysis tells you much more than just the condition of the oil. It tells you if you are experiencing a coolant leak, dirt ingestion, or fuel dilution for example, in the oil. If the viscosity is increasing, that could be an indicator that your equipment is overheating, oxidizing the oil, or reducing your fuel economy. Wear metals in the oil analysis may mean a part is generating wear or that dirt ingestion is causing abrasion. Just changing the oil won’t solve any of those problems and might make matters worse by hiding the problem until it reappears as an unexpected failure.


Think about how much a doctor can tell you about your physical health just by taking a small blood sample. Fluid analysis does the same for your equipment.


Pulling samples is a pain. Who has the time?


It’s simply a matter of establishing a routine fluid analysis program and making it part of your preventative, predictive and proactive maintenance program. Establishing the sampling procedure is part of this program. A variety of options exist to best fit your equipment. Many pieces of equipment are equipped with push-button sampling valves or other sampling valves, and while utilizing sampling valves is the simplest and cleanest way to take a sample, another way is to use what we call a “vampire” sampling pump. This sampling tool extracts the fluid from the compartment through a tube attached to a sampling bottle. Your fluid analysis lab can provide the necessary sampling tools for you. 


Some people take the sample at the time of the oil change, from the drain plug, but that can be messy and inconsistent. Ideally, a sample can be taken mid-drain, but mid-drain may be defined differently from one technician to the next. A sample taken too early or too late may capture more contaminants, creating erroneous or ‘ghost’ wear metals in the data analysis.


The report is confusing and hard to understand.


The lab will work with you to explain the report. The laboratory will flag any wear metals, contaminants or physical properties that need monitoring or any immediate corrective action which will be addressed in the laboratory’s diagnostic comments. After your first few reports, you will most likely be comfortable with the process and learn to read the reports with minimum guidance. The fluid analysis laboratories or your lubricant’s representative are always there to answer any questions.
