Editorial standards

Our editorial rules are designed to make comparisons useful, transparent and less repetitive.

Research

We prefer primary sources such as manufacturer manuals, technical specifications, public safety agencies and standards bodies. Secondary sources may be used for context but should not override authoritative specifications.

International scope

Units, voltage, fuel standards, sizing systems, terminology and regulations differ by region. We use both metric and imperial units when that improves understanding and flag areas where local verification matters.

Advertising independence

Advertising does not determine article topics, rankings or conclusions. Sponsored editorial content is not part of the current publishing model.

Corrections

If a factual error is identified, we aim to correct it rather than preserve a misleading legacy page. Contact us through the help desk.
