You’ve heard it all before. Over-the-top, baseless claims that “this is the oil that will change the way you run your operation” with nothing to show for them. You could trust our competitor’s claims (and suffer the consequences) or the truth.
“Other oils can leave behind soots and deposits.”
“Some engine oils aren’t made for the engines they’re supposed to protect.”
“No other diesel engine oil guards your fleet like Guardol®.”
Proven superior oxidation resistance
In an average of three pressure differential scanning calorimetry (PDSC) oxidation tests, Guardol ECT® proved its superior oxidation resistance compared to similar competitor products.
After pressurising samples with air to 100 psi heated to 210°C, Guardol ECT® demonstrated longer oxidation induction time, meaning better oxidation control.
No soot here
Guardol ECT® demonstrated better soot control from wear and soot-induced oil thickening. It was proven in an average of three moderately high-temperature thermo-oxidation engine oil simulation tests (MHT TEOST SAE 15W-40). These tests simulated deposits on the ring belt and piston under-crown areas.
In a test that circulated an oil and catalyst mixture over a wire-wound depositor rod at 285ºC, Guardol ECT® demonstrated a lower deposit weight and, ultimately, better deposit control.
Wear protection and long-term durability, demonstrated
In the critical DD13 scuffing test, Guardol ECT® demonstrated the same high level of wear protection and long-term durability, significantly exceeding the 31 hours-to-scuff limits required.
This is a fired-engine test performed in a 2010MY 12.8L DD13, in-line six-cylinder, diesel engine with all emissions controls that evaluate resistance to adhesive wear between the piston ring and cylinder linear interface.
