Amazingly the most mundane maintenance in a vehicle seems to cause the most controversy. I had used Mobile 1 for a long time in my previous vehicles, but I have seen a lot of negative opinions of Mobile 1 (lots of them with data to back them up). It seems like if you search hard enough you're going to find a group of people who think XXXX oil is the best and people who think XXXX oil is awful or terrible or even THE WORST!
So as per the break in procedures posted by Pelotonracer2 (http://www.fiestast.org/forum/fiesta-st-discussions/277-engine-break-101-a.html) I am running the OEM Motocraft until around 6000 miles then switching to a full synthetic.
So my question is this, for your Fiesta ST what Synthetic are you going to, or are you running, and why?
I'm watching was-an-M's thread where they're posting Blackstone analysis results and racking up lots of miles, and currently running Castrol Edge http://www.fiestast.org/forum/fiesta-st-maintenance/550-blackstone-oil-report-thread.html
I'm thinking I'm going to use Castrol Edge if only because they offer the 500,000/15 year engine warranty, and I plan on having the car for a long time. I see a lot of people saying Liqui Moly or Motul is a good option, but I've also seen dissenting opinions on these... You can't ever win with opinionated car guys can you?
(After searching a bit more I found the thread that I had read originally with oil opinions http://www.fiestast.org/forum/fiesta-st-maintenance/311-oil-oil-filters-what-do-you-like.html If you already posted in there, I have read it but I'm interested in what people think about the Castrol Warranty as well.)
