On Friday 14th December during the delivery of fuel to Caltex Milton, there was a mix-up of product whereby some diesel was placed into the underground unleaded 91 petrol tank, and some unleaded 91 into the underground diesel tank. This is highly unfortunate and we are investigating what happened. As soon as we were made aware of the mistake, we quarantined both tanks, emptied, cleaned and then refilled them with the correct fuel however we are aware that motorists were refuelling with this mixed product over the course of the weekend.
While we would not expect any long term damage to vehicles we’d encourage any motorist who refuelled for Unleaded 91 or Diesel at Caltex Milton between Friday 14th December and midday Monday 17th December who have noticed any performance issues in their vehicle to get in touch. A specific free phone number 0800 255 248 and a specific email address has been set up to help out, email@example.com whereby potentially impacted customers can provide their details and someone will be in touch regarding the next steps to assist with any vehicle checks and remediation. In most cases the repair may include emptying the fuel tank and flushing the fuel lines.
Once again we apologise for any inconvenience to our customers that this product mix has created. This incident has only affected Caltex Milton - no other Caltex sites were impacted.
