When looking at the VOA add packs, why does it appear that Valvoline, Castrol and PUP have the strongest? I know that does not count for the base oils that are used..
Because not everyone cheaps out like Mobil does. /sWhen looking at the VOA add packs, why does it appear that Valvoline, Castrol and PUP have the strongest?
If you look at something like Pennzoil Euro L 5W-30 you start wondering how it even works, or Shell Rotella T6 MV 5W-30. Yet they both have several OEM and industry leading approvals.Have you looked at Amsoil or HPL? I'd say they are "stronger" than the ones you mentioned.
Also, please do realize that not all additives show up in a simple ICP spectrometry analysis.

Most importantly, don't judge a lube by what's in the bottle. (inputs)
Judge it by how well it performs in the crankcase. (outputs)
So does Mobil 1, thinking about trying Castrol or Valvoline EP?Because not everyone cheaps out like Mobil does. /s
Mobil 1 sells some of the highest-quality, most-certified oils available on shelves anywhere. I’d hardly call them skimping on anything even though Mobil 1 is not my preferred brand.So does Mobil 1, thinking about trying Castrol or Valvoline EP?
VOA doesn't show enough. There are additives which don't appear in a VOA and you can't deduce the type of additive. VOA's are rather pointless. UOA is good for things like viscosity retention, fuel dilution, and excessive wear metals. Not so much about additives.When looking at the VOA add packs, why does it appear that Valvoline, Castrol and PUP have the strongest? I know that does not count for the base oils that are used..
Thanks. All this reading of the tea leaves (generally from untrained and unqualified individuals) using a $30 spectrographic analysis to predict the relative quality or future performance of a motor oil is quite a popular exercise on Bitog.It's really difficult to determine how good an add pack is from looking at an elemental analysis. Some additives are non-metallic and won't even show up. There are also many different forms of similar additives that are made up of the same elements. Some forms require higher concentrations than others to be effective.
Many additives also compete at the surfaces of engine components. An oil that has more calcium-based detergents will also require more friction and anti-wear additive to perform well.
How well additives hold up over an OCI also depends on the anti-oxidant performance of the oil. An oil with good oxidation performance won't require as much of certain additives.
Also, more is not always better. Some additives can contribute to deposits, increase friction, increase the risk of LSPI, etc.
There's a reason oil standards are based on expensive engine testing requirements, and not on elemental analysis (aside from phosphorus and sulfur limits).
I don't doubt that.. what do you personally use?Mobil 1 sells some of the highest-quality, most-certified oils available on shelves anywhere. I’d hardly call them skimping on anything even though Mobil 1 is not my preferred brand.
Strongest!When looking at the VOA add packs, why does it appear that Valvoline, Castrol and PUP have the strongest? I know that does not count for the base oils that are used..
I wouldn't say Mobil cheaps out, compare base stocks.Because not everyone cheaps out like Mobil does. /s

I run HPL in all my vehicles (except my Subaru with leaky HGs), in my zero turn and hydrostats, in my Polaris Sportsman 450HO, and my generator.I don't doubt that.. what do you personally use?
VOAs are necessary so you know initial concentrations, oxidation, etc, if you’re really going for maximum length OCIs. If you’re changing Mobil 1 EP at 3k, not so much.VOA doesn't show enough.

That sounds like me nothing like throwing away good oil..If you’re changing Mobil 1 EP at 3k, not so much.
Well, now you know. And as the PBS commercial after Masters of the Universe used to say, “knowing is half the battle”That sounds like me nothing like throwing away good oil..
That's why I usually don't even use EP, but I use Advanced protection.. because I change it within 4 to 5,000 MI.Well, now you know. And as the PBS commercial after Masters of the Universe used to say, “knowing is half the battle”
