Diesel oil has metallic based detergents which can cause excessive ash deposits (sludge) in your engine.
Completely not true! My 440 is spotless inside the valve covers. It's cleaner than when it was reassembled after a rebuild. Show me some proof that diesel oil causes sludge.
I just adjusted the valve lash on my 318 and everything was spotless, i'm running Rotella 15-40.

Here's some info from Caldwells speed shop website.
Lots of opinion there.
How do you come to the conclusion that what is stated there is opinion? They have charts from the various oil brands and additives that state the facts on those products from test laboratories. I don't believe they're making up those figures just to sell zddp.

Valvoline 10-40 with a little GM EOS.
I thought about using a synthetic, but it's too expensive for a daily driver + the guy who machined my rotating assembly said it's not worth the extra money and that a good number of racers still use conventional oils. He's done crankshaft work since the early 70's, in addition to drag racing his cars on the side, so he's pretty much seen it all.
Here's what Caldwells says about GM eos: Q: What about using GM EOS?
A: GM EOS contains less than 1/2 the amount of ZDDP as ZDDPLus. The concentration of ZDDP in GM EOS is diluted in a 16 ounce bottle. The proper level of ZDDP for high performance and classic cars is a minimum of 1300 PPM. To do this with GM EOS you would have to use 16-32 ounces of EOS significantly changing the viscosity of your oil and causing possible foaming within the oil.
ZDDPlus is clearly a better choice with one 4 Oz. bottle capable of raising 5 quarts of oil to a level of 1700-1800 PPM.
One 4 ounce bottle of ZDDPlus has the same level of ZDDP as 34.3 ounces of GM EOS.
Yeah but then you gotta watch out for TOO much zinc. The Reps at Royal Purple have advised that anything used regularly that is more than the needed 1100-1300 ppm of zinc/phosp. could cause an ashing or coking effect.
This, again, is why I like just using a good brand of oil such as Royal Purple that has just enough ppm of zinc, and then I don't have to worry about additives, how much zinc they have, etc, etc.....

I use Delo 400. $12/gallon. Has 1200ppm zinc, 1300ppm Phosphorus.
https://www.cbest.chevron.com/generated/MSDS/PDS29828888.PDF
That’s great to see that the Delo 400 “Low Emissions” CJ-4 stuff that passes 2007 EPA exhaust particulate emissions standards still has Zinc/Phos. @ 1300ppm/1200ppm as of May 2009.
Also notice the fine print below the specs:
"Typical test data are average values only. Minor variations which do not affect product performance are to be expected in normal manufacturing."
Sure does give them an easy out if they decide to make adjustments to the formula at any time.
