Liquid Moly Ceratec for the win. I had a bottle of it in my '18 during its first oil change at 500 miles. And a 2nd bottle on the next oil change, and a 3rd bottle in it on the next oil change that took place last Sunday. I swear by the stuff, zero tick here. But I also use a diesel grade full syn oil because I run an E85 tune full time. So I use Rotella T6 5W40...(yeah, in a not boosted coyote). I really think 5W20 oil isn't good enough for long enough in a high revving engine, especially when you run it on corn.Has anyone ever used this stuff? I have read in several places that it eliminates the dreaded "tick"
I really dislike adding stuff to my oil but it is Ford branded stuff.![]()
Think, or experience? I have a friend who autocrosses his GT. There's no better way to traverse the RPM range of an engine CORRECTLY than on autocross (rev-offs don't count). He uses 5W20 and hasn't thought twice about it. Been running Mustangs and building engines for decades.I really think 5W20 oil isn't good enough for long enough in a high revving engine, especially when you run it on corn.![]()
Doesn't matter to me if nobody but me takes the advice I give. Everyone has different opinions... especially about oil. I just stated what I use, personally between you and me, I don't really care what people use. They could dump kerosene in their engine for all I really care... LOLThink, or experience?

BTW, OP has a GT350 and it takes 5W50.
Like I said, take my advice or not, I really don't care. I'm not gonna argue about it either...In your "opinion" what makes 5W20 "inferior?" And inferior in what way? And to what and for what application? The weight and viscosity values do not deem an oil to be lower quality vs higher quality. I'd rather have a stout 5W20 in my Coyote engine than a shitty 5W50 and a bad compound profile. Which I had for 5 years and 45,000 miles on my previous car.
