My 2 choices I use on my vehicles are Redline and driven GP-1. The engines I rebuild I use redline, the mild cam/heads and intake engine on a stock old bottom end I use the GP-1
Any performance engine should be balanced to less than 4 grams, equal to 0.25 ounces imbalance, and that’s being generous. In reality, it’s not that hard these days with a decent shop with good equipment to hit 1 gram imbalance. NOTHING should be pulled from the box and installed without checking, even “balanced rotating assemblies”.That's sad. I can't let something go like that. I'm too prideful. I balance every crankshaft regardless. Even pre-balanced ones can have a rather crappy balance.
If you don't know the bearing clearance, and assuming you may have to start it in cold weather, I'd use HPL HDMO 5W-40 or Driven DT40 5W-40. If oil pressure is low (
Seems like OP could just look at Ford’s approval list for the Powerstroke oils…The HPS series oils from Royal Purple are close to that, there are lots of UOA on here.
I bought a whole bunch when Walmart clearanced it.Castrol GTX Classic
Oh ok, guess I didn't read the part about a diesel.Seems like OP could just look at Ford’s approval list for the Powerstroke oils…
OP is stating it’s got the same requirements…Oh ok, guess I didn't read the part about a diesel.
Do they have any certifications or 3rd party testing showing their oils exceed the certification requirements?I use TEXAS REFINERY .. also a salesman for them . We have a oil TRC PRO SPEC III WITH or Without MOLY
1400 ppm of ZINC and with a BN (BASE NUMBER ) of 15
I have a lot of testimonials of the sucess and longevity that is a result of the oil and the machines that run the oil.

It’s YOUR money they’re wasting if they don’t do these steps properly, so find a shop that respects your investment in the engine!
When I built my last performance engine I searched all the local machine shops for a specific balancing machine, because I had done my research. NONE of the “big name” local machine shops had anything comparable; Polarek Racing Engines was the only place at the time who was “local” and also had the right machine (its been so long I forgot the specific make/model now).Yes! The pre-balanced kits from Eagle and Scat are only balanced to within 10 grams. I'm not happy with it until I'm under 1 gram.
A 10 gram imbalance in a 383ci is >40 lbs imbalance at 6000 rpm. Imagine hammering the crankshaft with 40 lbs of force 50 times every second.

Correct me if I’m wrong, but doesn’t the Euro blend have a little bit more?Sounds like you want high phosphorous (that's the AW component of ZDDP, not the zinc). M1 TDT 5W-40 has 1100ppm phos/1300ppm zinc.
I run Mobil Delvac 1 ESP 5W-40 in our 351W, here's a VOA on it:

@zray1 you mean standard off the shelf Mobil 1 has that in it?
