Overpriced fake synthetic oil
Reviewed in the United States on December 26, 2018
If you read the data sheets on this, it is comprised of groups 1 2 and 3 oils. Those are all conventional!! Castrol was the first to make fake synthetics. Mobil 1 sued them, however the courts said its fine to market any oil as synthetic. They of course don't care about Americans. Then if you go on Castrols website. They recommend 3000 mile oil change intervals with this. Thats a whole lot less than Mobil 1, which rates super synthetic at 7500, M1 at 10k then ep and ap 15k and 20k.
Any oil with the API seal is good for 3000 miles!! You can just go with the cheapest Walmart supertech.
I am not some Mobil 1 super fan, however if you read Valvoline, Pennzoil, Castrol oils web pages, they all recommend 3000 mile oil changes!! If their oil is so great, why doesn't it last?
I bought this oil because it was cheaper than Mobil 1, but after doing some research won't buy again.
