Yeah, been using this stuff for 10 years. It's expensive but you get that with stuff that works. This stuff isn't your average woolies brand motor oil. This stuff is formulated on the basis that it will be used be proper people that care for their cars better than their children. My motor is Mickey Mouse clean inside because of this stuff. Minimal wear, no shiny bits on the filter magnets and every oil change is tested at the lab. Always comes back clear of issues. If you care about your car, you will give it this stuff. Bugger the kids, bugger the wife. The car deserves it. She takes you out on nice cruises. She brings you joy as you cruise past all the plebiscites in their eco friendly excuses for cars. She will thank you for it in the end. Trust me. I'm a random ... MoreYeah, been using this stuff for 10 years. It's expensive but you get that with stuff that works.

It’s definitely one of the best synthetic oils out there. My LS has had a bit of work done to her and she needs the good stuff 🥰
Some of the best oil.
Great product, slow delivery.
