Good price for a trustworthy product
I prefer Magnatec, but it's becoming increasingly more expensive and difficult to find a deal. GTX is still a trusted and good performer, and definitely worth the money if you keep to service intervals. I avoid cheap engine oils like the plague, as they've never proven to come close to top brands, regardless of the oil spec printed on the bottle. Those who know, know the benefits of genuine brand engine oil 😉

Ford focus 1.6 tdci 2014
I have used this oil first time, usually i use Castrol, MAGNETIC 5W30, A5. I feel the engine is quite responsive and light. ( Flushing was done before using ) it is summer season, the true result is to see in winter,
