9 September 2002: Castrol has reformulated its synthetic based GTX Magnatec engine oil to deliver better protection qualities as soon as the engine is started. The formulation makes new GTX Magnatec up to four times more effective at wear protection than ordinary oils.

The product now has a triple–layer formulation incorporating a protective coat which stays on the engine parts after it is shut down and will continue protecting the metal parts when the engine is next started. This benefit will specifically target the most common, and most damaging, type of journey - the short early morning or dusk commute or school-run.

Some 75% of all engine wear occurs in the first 10 minutes after the key is turned and the average journey takes only 12 minutes, according to Castrol research

Until now, GTX Magnatec has only been available to purchase in 4.5L and 1L packs from a network of retailers and garage forecourt in the Republic of Ireland. However it is also available in service centres and garage workshops.
