Castrol | GTX Premium Mineral Engine Oil 20W-50 - 1L

Castrol GTX 20W-50 is one of the world's most trusted premium mineral engine oils, engineered specifically to protect high-mileage engines against daily sludge challenges. Severe driving conditions, extreme heat, and heavy loads can cause combustion by-products to accumulate as a thick, tar-like substance that clogs critical oil pathways. Castrol GTX features a unique double-action formula that effectively cleans away existing sludge while preventing new build-up to extend engine life and optimize mechanical reliability.

Key Specifications & Approvals:

• Fully compliant and certified against the American Petroleum Institute technical categories API SL / CF.

• Backward compatible and suitable for applications requiring earlier API SJ or SG specifications.

Usage Instructions:

• Drain the used engine oil completely while the engine is warm to ensure cumulative carbon particles are safely removed.

• Always install a fresh, genuine OEM oil filter to maintain the full cleaning capabilities of the new mineral fluid.

• Carefully pour the fresh fluid into the oil neck matching the exact capacity outlined in your vehicle's service manual.

• Let the engine rest briefly, then use the physical dipstick to verify that the final fluid level sits perfectly within the safe markers.

Suitable For:

Ideal for older passenger cars and high-mileage vehicles (produced from pre-1990 to early 2000s) operating in warm/desert climates that specifically require a 20W-50 viscosity grade.

Note:

This lubricant is a premium high-viscosity mineral oil. Please consult your vehicle manual and avoid using it in ultra-modern or downsized turbocharged engines that strictly require thin, full synthetic lubricants like 0W-20 or 5W-30.
