## Why SUVs Are the Highest-Risk Category

SUVs account for more than 40% of new vehicle sales in New Zealand, and the majority of popular SUV models — Toyota Fortuner, Ford Ranger, Ford Everest, Mitsubishi Pajero Sport, Nissan Patrol, Land Rover Discovery — offer diesel variants as the mainstream option. The combination of high market share and widespread diesel availability creates a statistical inevitability: more SUVs mean more SUV misfuels.

## The Shared-Vehicle Problem

Family SUVs are particularly prone to misfuelling because they are driven by multiple household members who may have different fuel type awareness. The primary driver — typically the one who bought the vehicle — knows it takes diesel. The partner or teenager who borrows it for a weekend trip may not have the fuel type as ingrained habit. Fleet SUVs face the same issue across a larger pool of drivers.

## What Recovery Looks Like for a Diesel SUV

A standard diesel SUV misfuel recovery involves towing to our workshop for a full fuel system manufacturer-spec fuel system recovery; replacement of the primary and secondary fuel filters; and fresh diesel to specification. On a large SUV with a 70–90L tank, the total fuel removal and replacement volume makes this a two to three hour job. recovery is fully itemised on our rate card–significant cost for a catch-it-at-the-pump incident; significant cost if the vehicle was driven on the wrong fuel.
