Right; when it warmed up, it misbehaved. That was the point I was trying to make.
And, when I used oils thicker than _w-20, it didn't misbehave when warmed up. I'm not the first person to make this claim with a misbehaving 3v Triton.
And, now it doesn't misbehave at all because the defective parts (and a whole bunch of others that got in the way) have been replaced with new ones.
And I'm running 5w-30 with the new parts. That's more a matter of insurance for my vehicle. It's running solid, using a half-quart in 3,000 miles, and has been quiet since all that work I did 5,000 miles ago.
So, yeah. 5w-30 for me.
I'm sure the 5w-20's are damn fine oils, I've read about their development and the tests they have to pass. But, this engine won't ever see another drop of it as long as I'm running it.
No problem with your choice whatsoever. In my opinion 5W30 is just fine, and I've seen no data to the contrary.
