No Oil Keeps Engines Cleaner

FIND THE RIGHT OIL FOR YOUR ENGINE

Environmental factors such as poor fuel quality, hot weather and stop-start driving conditions can lead to sludge, varnish and carbon build-up in your engine: three factors that reduce engine life, power and fuel economy.

 

Castrol® GTX® Ultraclean is a synthetic blend engine oil available in 10W-30 grade. Its double-action formula has been proven to clean away the sludge that can block engine oilways and helps prevent new sludge formation thanks to its synthetic technology.
