The Joe Gibbs break-in oil is recommended for break-in. There's no question about ever running that as my regular oil!
Joe Gibbs also makes Driven Hot Rod Oil that Golen sells for after break-in, or "forever," if you don't change brands. It's supposed to be a "street" version of his racing oil made specifically for older cars and street rods, but with an additive package that makes it suitable for street use.
That's the oil that I wanted to know how it stacks up against Rotella, not just in the zinc and phosphorus numbers, but also with regard to the other metrics as well. Is it just crappy oil with a lot of zinc added to it? I doubt it, but I really have no idea.
I think I'll go ahead and run the hot rod oil in the next fill and see how it does. I'll eventually be sending off a sample to Blackstone anyway when it's time to change it again, so I'll just wait until then to see how the numbers stack up against Rotella.

Rotella probably has enough zinc to be fine in a stroker (it looks like the Joe Gibbs "Hot-Rod" oil has arrouns 1300 ppm ZDDP which is very close to T5/T6), but I'm not sure that it will meet your warrenty requirements if it requires the use of oils specifically marketed as "High-Zinc".

I guess I read it too quickly, the phrase "This is what Golen sells for their strokers for those who don't want to use the additive" originally led me to believe that you needed to use what they sell. I'm not a fan of additives. I would use whatever pre-formulated oil is best suited for your engine. I tend to think the T6 is fine. This isn't some kind of top-fuel funny car at the drag strip and I didn't see anything in the Joe Gibbs information that says it has extremely high ZDDP - only mentioning it contains more than PCMO.

I topped off with Marvels in between oil changes, then ran Seafoam for 55 miles before I changed the oil. When I drained that punk I was shocked at how black the oil was. I intend on Seafoaming again prior to the next oil change.
Curious to see how she reacts with the T6 and the big napa filter.

Ya pretty much looked just like that. I guess that Seafoam really does losen up the built up gunk.

.......and synthetic oil will loosen up the deposits left behind from the dino oil. Synthetic oil (of the same vis) increasing oil pressure seems wacked.

Don't forget that when a filter clogs up to the point of being near-impenetrable the bypass valve opens up. A filter full of crap will play all kinds of havoc with your pressure.

Damn. That'll do it...
I know lol. Makes me want to do a remote mount just to have it vertical. I haven't changed mine yet, I'm curious how much it'll weigh...

And yes we have a napa here. Contrary to popular belief California is more than just LA and the Bay Area. There are tons of small farming communities up and down the state. Where do you think your food comes from?

If you notice it's particularly filthy you might change it. T5 has a slug of calcium in it so some deposits may be dislodged.
I had to scroll up and see what you were talking about. Totally missed that typo.
What? lol I asked if you have winter
