Motorists who are unsure which top-up oil to use in their car can now use a special text service to find out – while they wait.

Recent research commissioned by Chevron Global Lubricants has shown the introduction of extended warranties and differing service intervals has left motorists confused about which top-up oil to use.

Many are even delaying topping-up and risking unnecessary damage to their vehicle as a result.

In response, Chevron Global Lubricants has launched an SMS text service for passenger cars – one of the first of its kind in the UK.

Customers can text their registration number to a special number that is located next to the Havoline display and the correct Havoline oil grade, recommended by the vehicle manufacturer for the make and model of their car, will be texted back to them while they wait.

Customers will also be sent a 'get me home' choice of oil, for emergency use should the driver be caught short or supplies of the best oil for his vehicle not be immediately available.

The SMS service number is now available in forecourt shops across the Texaco branded retail network and at selected retail outlets. It can also work for cherished plates and will cost drivers only 50p per text plus the standard network charge.
