Castrol Gtx Ultraclean 10w – 40 A3 – B4 Semi Synthetic Engine Oil – 4 Litre

About Castrol 10w40 GTX Semi Synthetic Engine Oil:
Heavy traffic, poor fuel quality, harsh weather and exceeding oil change intervals can be tough on your engine. These driving conditions can all cause the build-up of a thick, tar-like substance, inside your engine, called sludge. If untreated, it can rob an engine of power and fuel economy. Ultimately it can cause engine failure.

Castrol GTX is specially engineered to prevent the harmful build-up of sludge. It reduces oil deposits and provides daily protection for your engine and provides 25% better protection against sludge than the latest industry standard.

When to Change your oil:
Experts recommend you change your oil every 3000 miles but it can vary quite a lot from car to car. Check your owner’s manual to see what the manufacturer recommends for your car.
It’s a good idea to check your oil level regularly as it’s common for cars (even brand new ones) to burn some oil in-between services. To avoid paying high garage forecourt prices it’s a good idea to keep a 1 litre top-up in your boot.
