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 Ultraclean is a synthetic blend engine oil available in 0W-20, 5W-20 and 5W-30 grades.  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.  In fact, it provides up to 1.4X better sludge protection than is demanded by the latest industry standard.  If keeping your engine clean is important to you, it's good to know that no other oil keeps engines cleaner.   1.4X superior sludge protection compared to tough industry standards**  Advanced protection against viscosity and thermal breakdown  Superior protection against high-temperature deposits  Premium-quality base oils and anti-wear additives that help extend the life of your engine  * When tested in engines with a high level of sludge  ** As measured in the Sequence VH Sludge test vs. API SP test limits  Meets or exceeds API SP/SN PLUS/SN  Meets or exceeds ILSAC GF-6  Meets Ford WSS-M2C946-B1  Meets Ford WSS-M2C961-A1
