The Proof Advanced Protection

Field tests confirm that Super-D XA® and Guardol ECT® oils fight wear, oxidation and deposits.

Our diesel engine oils with Liquid Titanium® protection additive help engines last longer by providing an extra shield of protection against engine wear.

Advanced Wear Protection

Final field tests validate that our diesel engine oils with Liquid Titanium protection additive reduce wear across engine platforms in on- and off-highway applications.

In off-highway testing, observed concentrations of iron in used oil reveals that our diesel oil with Liquid Titanium protection additive reduces engine wear. Less iron in used oil means less engine wear. The results reflect over 250,000 hours of off-road applications under varying conditions and equipment types.

In on-highway testing, lower iron concentrations in used oil corroborate the enhanced wear protection of our diesel oil with Liquid Titanium protection additive. Less iron in used oil means less engine wear. The testing included independently operated commercial fleets with various engine platforms and vehicle types. The results reflect over 7.9 million on-highway miles under varying conditions and service types.
