CORVANTA FUELS / PRACTICAL GUIDANCE
Warning signs need evidence, not a guess.
Changes in fuel appearance or equipment performance deserve attention. They do not identify a cause on their own.
Source and editorial review: · General education, not a site assessment.
Recognise a reason to investigate
Unexpected water or sediment reports, repeated filter restrictions, hard starting, rough running, smoke or reduced power can prompt an investigation. Similar symptoms can have several causes, including equipment faults and operating conditions. They do not prove that a fuel batch is contaminated.
Escalate through the right people
Follow the equipment manual and the site’s safe-stop or isolation procedure. Inform the responsible site person, supplier and equipment service provider. Avoid continuing operation against a manufacturer warning. A qualified technician or laboratory should decide what evidence and representative samples are needed.
Preserve useful context
Record the batch or delivery reference, receiving tank, affected equipment, timing and observed symptoms. Preserve maintenance and filter records. Have trained personnel collect and label samples using the laboratory’s method; improvised containers or collection can distort results. Do not blend away a suspected problem or add unapproved chemicals.
Interpret results with the equipment context
Laboratory findings, sampling quality and service history help distinguish possible fuel issues from other causes. Agree corrective action with qualified parties. Buying from any supplier, including Corvanta, does not eliminate every contamination risk across transport, storage and handling.
