Castrol GTX 10W-30 Conventional Engine Oil
This Castrol GTX engine oil uses a conventional base formulation in a 5 qt bottle. It carries a 10W-30 SAE viscosity grade for gasoline engines. The product meets API SN, SJ, SL, SM standards along with GM 6094M and ILSAC GF-3, GF-4, GF-5 specifications. It is suited for routine maintenance on compatible vehicles.
Drivers needing API SN conventional 10W-30 oil
This oil fits gasoline engines where the manufacturer specifies a conventional 10W-30 grade meeting the listed API and ILSAC standards. It is not intended for engines requiring full-synthetic base stocks. Buyers whose manuals call for a different viscosity grade or a diesel-specific rating should select a different product.
SAE 10W-30 viscosity with 142 viscosity index
The oil delivers a kinematic viscosity of 75.1 cSt at 40 Deg C and 11.31 cSt at 100 Deg C. Its viscosity index of 142 indicates stable performance across temperature changes. A flash point of 392 Deg F and pour point of -32.8 Deg F support reliable cold starts and high-temperature protection. This specification set determines if the oil matches your engine requirements.
