“This product is excellent value, treating many tankfuls. It seems to improve the throttle response and make the car noticeably quicker. It also seemed to improve the economy by 1 -2mpg so I'd recommend giving this a go as Millers products are high quality and represent value for money.”
“Used this in our VW Transporter campervan almost since new.So far so good.120,000 odd miles. No issues, touch wood.Sure the power did increase and it just runs better,also towing a big German caravan. Dunno about mpg but I'm a convert.”
