Quaker and Pennzoil is also sold in 946ml. Personally I like it, because many 4 cyl. like my Echo take 3.78 L of oil. Amsoil has been sold by CTC for over a year, most stores also sell Redline. I used Amsoil in my Focus and always thought it was a great product, kept the oil in for 20k and changed the filter at 10k. When I changed the oil it was not any darker than other brands at 8k. I traded the Focus at 170k and the engine just purred, had to be the best part of the car

I don't know if I will switch the X-Trail down the road, it has been on Mobil 1 since the 1st service at 6k, that engine also purrs.
