Ever since I've had my 5.4L modular Ford V8, it's had an annoying cold start ticking when the temps fall to the 50 deg and below range. I've heard hundreds of reasons, piston slap, faulty filter, fuel injector noise, exhaust manifold leak, bad lifter, had 'em all checked, not a single problem diagnosed or found. It's something I just learned to live with, as have hundreds of thousands of other Ford modular V8 owners.
I've always used M1 0W or 5w30 in the winters, changing it right around Thanksgiving. Last year, I switched to SSO because I bought a bunch at preferred customer pricing. Well, last winter I heard the cold start ticking only on the very coldest of mornings, usually when it was in the teens and twenties below zero, and then it went away real fast. Spring came and SSO came out in favor of HDD.
One month ago I changed out the HDD for my winter fill, 6 qts. of M1 0w30 AFE. Darned if the cold start ticking started again with a vengeance. I wondered if last winter could be just a coincidence, or is there really something about the SSO that quieted my mod. One week ago I had enough and dumped the M1 for 6 qts. of SSO. The cold start ticking went away, and this past week has been colder in the mornings than the past 3 weeks before it.
Is there something in the SSO chemistry that makes it superior to M1 as far as Ford modular V8's are concerned? I don't know, all I know is that SSO has pretty much stopped all cold start noise for me. I've only got one or two more winters at best on this 11-year-old beast of an Expedition, but I know what I'll be filling the crankcase with next winter and any more after.
