About Warranty Secure

Switching to high-end synthetic oil may seem like a cost — but it quietly pays you back in better fuel economy and fewer service issues.

In most fleets, fuel injector cleaners alone can generate enough fuel savings to cover the cost of premium synthetic oil — with long-term engine protection as an added bonus.

1.7%
The Long-Term Value of Initial Gains...

Starting small is a powerful approach. That baseline of 1.7% fuel economy improvement isn’t just a number—it’s an open door to compounding, sustainable fleet efficiencies. This initial gain is what you can easily expect by simply using a high-quality fuel injector cleaner, delivering an easily expected gain of around 1.7%.

This calculator sets the initial improvement conservatively at 1.7% because this is achievable with SN Plus synthetics, but it’s just the tip of the iceberg.

When you stack these initial gains with the reduced friction achieved by upgrading lubricants across all moving components (engine, transmission, and drivetrain), real-world results can easily reach 8%, 10%, or even 15% or more.

Many fleets are starting from a low baseline, meaning the switch to premium synthetic lubricants like XL | Extended Life and Signature Series formulations often leads to dramatic, measurable performance gains that quickly surpass this minimum threshold.
