What off the shelf brand and viscosity dino oil do you guys prefer. I'm getting ready to change the break in the oil in my fresh stock 440 magnum.

Rotella diesel oil, I thinks its 15-40. Even the reduced zinc formula is still pretty good

Re: What brand of dino oil do you guys prefer? - 05/18/09 08:39 PM
you're about to get 50 replies claiming 50 different brands is best!
I like the rotella stuff too, but at 15w40, I wanted to see if something a little thinner would work for me and save a few HP too, but there's no HD diesel type oil less than a 15w40, so I picked up some royal purple from the local Jegs storefront thats 10w40. haven't run it yet though.

Here's some info from Caldwells speed shop website.
Q:
I use Rotella or other diesel oil in my classic or high performance car. Doesn't this provide the ZDDP protection necessary for my car?
A:
Diesel oil is engineered with a higher amount of dispersant and detergent to deal with the increased amount of soot and other hydrocarbon by products in a diesel engine. This high amunt of detergent can increase the decomposition temperature of the ZDDP reducing its effectiveness as an anti-wear agent. Diesel engines are manufactured with this issue in mind. Gasoline engines are not.
Typically the viscosity range for diesel oil does not include the very low 5w and 10w values. Tighter bearing clearances in passenger automobiles often require free flowing oil, diesel engines typically have larger bearing clearances minimizing the need for free flowing oils.
Diesel oil is not optimized for film strength as needed in high performance and classic automobiles. For a given viscosity high detergent diesel oil has a lower surface tension and lower shear strength which can cause increased bearing wear, especially in high reving engines.
Diesel oil has metallic based detergents which can cause excessive ash deposits (sludge) in your engine. These deposist in worse case scenarios may cause detonation especially in high compression or supercharged applications.
Newer diesel automobiles are being designed with catalyic converters the implication is that ZDDP levels will be reduced in diesel oil making the discussion a moot point as ZDDP is removed diesel oils will become totally unacceptable.

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.

I don't know who writes for Caldwell's speed shop, but when I got to the last sentence I thought: "pretty strong statement..."
So I looked at Shell's Rotella website and find that their single grade Rotella T is available in 10, 20, 30, 40, and 50 weight viscosities and is API CF-4, and SJ as well as CF and SH. So I looked at the multi-viscosity 15-40 and its a long list including API SM and SL, and they show information that the wear resisting properties of the new formulation are improved over the older stuff.
Now who 'ya gonna believe?
edit: Say, 'ya don't suppose the speed shops sell expensive oil additives and specialty motor oils do 'ya...?

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.

Here's the reply i got from Shell about Rotella...
With the introduction a couple of years ago of ILSAC specification GF-4 and
API specification SM for gasoline-only engine oils, the amount of
phosphorous in the oil had to be reduced to prolong the life of catalytic
converters. Zinc-based anti-wear compounds, which also contain phosphorous,
were reduced as well. These zinc compounds work well to protect flat tappet
engines from excessive wear, so the modern gasoline-only engine oils are not
as effective in this regard as they once were.
Diesel engine oils don't suffer from the same requirements to protect
catalytic converters, so the amount of zinc-based anti-wear additives
remained high. Products like Shell Rotella T Oils, which also carry API
S-series licenses for gasoline engines, have found favor for flat tappet
engines.
There has been a recent change to the API specification required for oils
used in 2007 big rig diesel engines to reduce particulate emissions, API
CJ-4. As a result, the zinc content in Shell Rotella T Multigrade Oils has
been reduced slightly from about 1400 ppm to about 1200 ppm. Even at these
slightly decreased levels, Shell Rotella T Multigrade Oils still have at
least 50% more of these anti-wear additives as most current gasoline-only
engine oils. These levels of zinc have historically offered good protection
in flat tappet applications.

Edward Calcote

And Kendal
Kendall® GT-1 High Performance Motor Oil is a high-quality
engine oil specially designed for use in gasoline-fueled vehicles
operating under high-temperature or severe driving conditions,
such as towing heavy loads, as well as in competition engines
and high-performance street engines.
GT-1 High Performance Motor Oil is formulated to provide
excellent wear protection, to minimize the formation of sludge
and varnish, and to resist viscosity and thermal breakdown, even
in severe service. It also protects against rust and bearing
corrosion, and has good foam resistance. The SAE 20W-50
viscosity grade is fortified with additional zinc
dialkyldithiophosphate (ZDDP) additive to provide enhanced
wear protection and oxidation resistance for use in the most
demanding applications. It is particularly recommended for use in
turbocharged engines and in high-performance engines with
flat-tappet camshafts, especially during the critical break-in
period.
Applications
• Gasoline-fueled passenger cars, light trucks and sport utility
vehicles that do not require an ILSAC GF-4 oil for warranty
coverage
• Competition engines and high-performance street engines
• Nitromethane-fueled drag racing vehicles (Nitro 70 grade)
• Gasoline engines where monograde engine oil is
recommended
GT-1 High Performance Motor Oil meets or exceeds the
requirements of:
• API Service SM, SL (all grades except SAE 50 & Nitro 70)
Features/Benefits
• Excellent resistance to viscosity and thermal breakdown at
high temperatures
• Protects against sludge and varnish formation
• Excellent wear protection
• Protects against rust and bearing corrosion
• Good foam resistance
• Formulated for engines equipped with turbochargers or
superchargers
• Enhanced wear protection for engines with flat-tappet
camshafts (SAE 20W-50)

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.....

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.
