Bought a new 2016 Focus. 2.0L GDI. I know GDI's mean two things, fuel dilution and deposits. So I went looking for a very thick 5w-20 that also tests well in the TEOST.
I settled on Castrol Edge EP (Gold Bottle). 100* Cst is 8.9, higher then PUP or Synpower. It also scored the best in Amsoil's 2013 TEOST test. I will be following the IOLM with a maximum of 1 year or 10k miles. I am going to test 3 filters for gas mileage, RP, Purolator Boss and the Purolator One. Which ever gives me the best mpg's will win. Thoughts?
Also, my top off oil will be GTX Magnatec 5w-20. Its Cst is 9.1
