Would there be any harm in switching to a full synthetic at 3K miles?
Hell, I'm sure it's just fine keeping the factory oil to 10K or OLM. It's just after owning Euro cars for so long it feels wrong to use a blend.
Like the cat said, full syn oil doesn't cause ticking. On the other hand, too thick of an oil or a different oil filter could cause ticking. If a different oil filter causes ticking, it's nothing to be alarmed about.After reading about all the ticking after first oil change I'm a little worried now. Perhaps it's best to stick with the syn blend?
I have not had any ticking issues.
That is basically what my plan is.OP, I switched to Pennzoil Platinum 5w-20 and a Motorcraft FL500S filter at 27xx miles on my 2018 GT and have had zero issues. I am coming up on 10K miles and about to change oil again. No BBQ ticking or any noise from the engine that is to be of concern. I daily it and push it hard when I can and its been solid so far.
In other words, the Ford semi and mobil 1 are nearly equivalent.Opening this can of worms. Mobil 1 makes some full synthetic oil using group IV base stock , PAO (poly-alpha-olefin) full synthetic base stock. This is not what they add at the US factories. This is also not the oil you get at Walmart. That oil is Group I, II, and III blended base stock (Dino) oil. They are allowed to call this a full synthetic in the USA only because a judge said they could.
