Very good quality oil 👍
I’ve used this oil for my car and it works perfectly, the engine runs smoother and quieter. The delivery was quick and the packaging was secure. A trusted brand that I’ve used before and will buy again. Great value for the price.

Good quality oil.
This is very good oil and compatible with my 1.5dci diesel engine. My vehicle has 130k on the clock and I would recommend this for cars with high mileage. I can tell the difference in engine noise between this and a cheaper brand I normally use. At only a few quid more that cheap oils, this will be my new go to twice a year. However oil changes need not be that frequent with this smooth stuff. At 5l, it is also the perfect size as my car takes around 4.8l.
