Excellent for Toyota engines!!
Always used for my Toyota Auris 1.6 vvti, have done just a bit over 4.2k miles (Mostly Motorway M11) for work. Have just done a visual check on dip stick, oil is still light golden colour. I will be using this Oil again, difference in higher RPMs and whilst under heavy acceleration. I have noticed 10% better fuel efficiency then before. Quicker cold start ups to reach opp temperature then before also. Will be changing again at every 5k mileage. Thanks!

Good stuff.
High milage diesel with a bit of a whine, now quieter and, it seems, smoother! Does what it says on the tin (plastic container)!

Happy customer here, highly recommend it
I replaced the engine oil myself this time and feel much more satisfied than when I relied on garages. The oil quality is great, and the container is sturdy and convenient for any future use. I’ll update you in a few months to share how the oil performs over time. Worth the money to be honest, car engine feels more smooth. I will report the performance in due course. I hope it will keep functioning well and it keeps the engine cleaniness for the next year!
