Full synthetic oil in the ST or other Focus?
Ford list a Ford specification for their oil in their manual, rather than the industry standard APIs or Euro standard codes. Anyone know what the equivalents to these codes are?
Basically, I want to switch to full synthetic, but appears that the ST engine has an appetite for semi-synths, more than full synths. All of the Australian oil companies, except Castol, recommend a semi-synth, with Mobil listing a special MOBIL SUPER FE SPECIAL 5W-30 oil. Castrol recommend their 5W30 Formula R, along with their Magnatec.
Is anyone running full synths in their Focus? Does Ford have a problem with full synths in their cars?
