0w 30 engine oil from leading oil manufacturers. All brands of engine oil we stock meet the latest API and ACEA requirements, so you can be sure it ticks all the right boxes on quality. To achieve this standard, high quality base engine oils are blended with advanced technology additives to give high anti wear and detergency properties in all mineral, semi synthetic & fully synthetic motor oils. If you're wondering what the numbers mean... the first number followed by a 'w' describes the thickness of the oil when starting the car, the second is how thick the oil is when warmed up and running round the engine. Both numbers are vital to ensuring that the engine is properly lubricated and no damage is caused.
