Opti-lube is still #1 in Lubricity for Diesel Fuel!

Recently, at our own time, cost and effort, we compiled new HFRR (lubricity) test scores for our additives, as well as those of 25 competitors products.  (See past blog post for more information on what an HFRR test is.)

What did the results show?

Our Opti-Lube XL Formula reduced wear by a whopping 52.78%.

Our Opti-Lube XPD Formula Reduced wear by 36.21%.

And our Opti-Lube Summer+ Cetane Formula reduced Wear by 31.91%.

That's an average of almost 37% reduction in wear compared to the base pump diesel fuel used for testing.

What about the 25 other Competing Additives?

They did not fare as well. The average reduction in wear was only 2.58%, with the highest score at 7.47% reduction in wear. Sadly one of the additives did not alter the base fuel at all and shockingly, five of the additives actually reduced the lubricity of the base fuel, one by as much as 10.6%.

What are you putting in your diesel?

Some use ATF and 2 Stroke Oil, thinking they increase the lubricity of their Diesel Fuel. How did they rate?

ATF only hit 5.56% reduced wear. Although better than some of the actual Fuel Additives, still not great.  (Tested at .78 oz per Gallon)

2 Stroke Oil only reduced the wear by 0.32%. At less than half a percent that’s barely above base fuel alone.  (Tested at .64 oz per gallon)

This shows us that even if you were to put a whole quart of ATF or 2 Stroke Oil in your fuel tank, the wear reduction would not come close to what Opti-Lube can do for you. (See past blog post for more info on ATF, 2 Stroke Oil, and Power Steering Fluid used for Diesel Fuel.)

We are proud to report that these test results again prove one thing:

Opti-lube is still #1 in Lubricity for Diesel Fuel!

We hope our continued testing will help customers make informed decisions when deciding between Diesel Fuel Additives.

*All tested additives were purchased by Opti-Lube from either an online or local retailer. They were all blended at the higher recommended mix ratios listed on the bottle with local pump diesel fuel and sent into the lab for testing. Each sample was only marked with a letter for identification, A-Z and then AA, BB and so on. Several test samples were sent in more than once at different dates to verify consistent results.
