which 5w-30?

[svenson]

ESP 0W-30 virgin oxidation of 32 as of 4/25 indicating a fair amount of esters.

taken this post ftom a momber on a same topic about M1 esp 0-30

is this 5-7% a true verified amount of esters that this oil has? or is it just a a guess?
if it is true,is this a fair amount of esters for an oil to have such a high oxidation numbers on a VOA?

i mean according to that post ,how much ester content other perfomance brands have?

second question,is this an APIL SL -like castrol 0-30- oil which only meets sn and sp requirement and tests? if i understand correclty.

@buster is much smarter than I, so hopefully he’ll chime in. I do know a virgin oxidation over 30 indicates esters are present. Most OTS oils are under 10 and many boutiques are 50-70, I don’t believe you need very much to be effective. The 7%-15% is thrown around a lot.

These are just very general estimates. Oils that use an ester co-base generally show an oxidation value>30. It's impossible to determine the exact amount based on oxidation value and FTIR peaks, but you can see a strong correlation and get some idea. When I spoke to Dave at RL I asked him about this and he told me some grades use up to 40% which is extremely high for a PCMO. However, RL's oxidation value is also on par with Valvoline Premium Blue Restore and HPL EC.

I would guess the ESP line to have 5-8% POE. Amsoil SS 10-14%, RL - 15-40%, Valvoline Premium Blue Restore - 50%. Very rough guesstimate.

For another point of comparison, where would you estimate HPL PCMO’s ester content?

I don't really know but HPL also uses ANs so it has very good solvency.

so the new oil isn't that bad after all?

I am not sure that anyone here said ESP 5W30 is “bad” oil.

 

[Pao99]

Even though it doesn't have a PAO base but an HC base, it's still a good oil? Why?

It’s the ester content that people here are more excited about in the 0W-30 variety.

The bottom line is that the 5W-30 weight still meets the same (plus LL) approvals, so however they did it, it holds up to the same rigorous tests.
