THIS FULL SYNTHETIC HAS EARNED ITS STRIPES
Castrol GTX Full Synthetic carries on in the GTX tradition of proven performance and protection and is designed to meet the needs of the 21st century car parc.
MAXIMUM PROTECTION TO HELP EXTEND ENGINE LIFE
Castrol GTX Full Synthetic motor oil provides maximum protection to help fight the impact of severe conditions that can potentially shorten engine life. Tough driving conditions like idling on congested highways and frequent, short trips put peak loads on critical engine parts and create engine wear. Environmental factors like heat can lead to sludge, varnish and carbon build-up in engines.
Castrol GTX Full Synthetic has been proven to dramatically reduce engine wear- 6X better than the industry standard.* It also cleans away old sludge** and protects against new sludge formation 1.3X better than required by the latest industry standard.†
And it maintains this unsurpassed level of engine protection for up to 10,000 miles between oil changes, as needed.
