2012 F-250, Fiesta, Taurus
Use OLM with a full synthetic, usually 7.5K-10K
Always use a Motorcraft or FRAM Ultra or Tough Guard
Fusion
Every 5,000 with synthetic blend or 7,500 when I run full syn
Always use Motorcraft or FRAM Ultra or Tough Guard, although I'm currently running an August 2015 built Puro Classic as an experiment
2015 F-250
Only did 1 oil change so far, but planning on every 5,000 with full syn & a Motorcraft since this truck tows all the time.
