“very happy, used this for my Focus mk2 petrol in the past 7 years had 6/7 oil changes as I did around 60k miles with it, and engine is smooth and the whole mileage of the car is 213k , but pristine, no smoke, no engine light, so definitely does the job, Highly recommend, 100% please before you flush the oil use an engine flush solution just to do a proper clean as that's how i do it !!”
