this is a deposit formation test that high moly oils are exempt from in certain viscosities as they fail it. the deposit formation tests are more stringent in euro manufacturer specs.

Thread 'Amsoil TEOST 33C - High Mileage Comparison'

Feb 18, 2024

We've had quite a few good posts about the TEOST 33C test and whether it's relevant. Star polymer VII, very high levels of moly, concentration of VI, AO and base oils all play a role.

Are you actually saying that HPL Euro (and HPL No VII) should not be used, with 2024 technology in play ?

Lots of moly.
Also lots of calcium.

I am gonna guess that 2024 HPL Euro (and No VII) is nothing like the oil that was tested in 2014.

I'm using a high moly, high calcium oil myself on a 2024 car, so no....

I don’t believe anything he says. My car is running fine on NO VII 10w20 “euro” HPL. If it was so bad I’d have problems by now.

Clarification for everyone

The VW504/507 oils are low moly in favor of boron. This is their Euro 0w and 5w30 oils are 504, NOT 502.

The 502/505 add pack is 100% different. This is where the moly is. That's going to be their Euro 5w40 and SuperCar 0w30 and 40, 5w40 and 50 oils. It also includes their no VII Euro oils.

They also have a 508/511 oil that is Euro 0w20, no clue what that is for moly, etc.

Not all Euros are the same.

European oils/specs are ridiculous.

Nobody is gonna tell me I can't have my slug o' moly !

While high amounts of MoDTC can show a worse result in Teost (deposits), the same doesn't apply to all moly-based additives. There's also discrepancy as to the validity of Teost and how it correlates to the real world. Assuming it does correlate, the base oils they employ (low volatility, high oxidation resistance) combined with ester and AN will nullify any deposit formation. This had no bearing on their decision regardless.

Oil formulating is a careful balance of chemistry. Sometimes, things just don't synergize the way you hope they will. HPL is diligent in testing every change to every formula extensively. If they withheld a specific additive, there's a good reason for it.

The choice to withhold moly top treatment from the 504 oils is due to clash with the additive package. Sometimes, things just don't synergize the way you hope they will. HPL is diligent in testing every change to every formula extensively. If they withheld a specific additive, there's a good reason for it.

Definitely comes down to final product. With the solvency they use in HPL, any potential deposit formation is likely mitigated.

I get that there is chemistry clash/synergy issues, but my question was more along the lines of "is there a reason they favour/use moly whenever they can and not boron".

The Euro 40 has a ton of moly...

That's because the Euro 40 isn't the same as the rest of the family, it's actually Super Car formula dumped in a Euro bottle, just for that viscosity.

Or....is the Euro 40 formula dumped in a Super Car bottle

 

[hemioiler]

Nope those 2 are the same oil just in different bottles, that was confirmed by somebody else here a while ago, since they have moly it's the SuperCar formula not the other way around.

Got it...I do have a Supercar!

Currently running Premium PCO 0W-20 in my wife’s suv; service appt in about a week for that vehicle and will switch over to VRP 5W-30 that’s remaining in my stash since we won’t keep her vehicle more than a couple of more years. Sending the used sample to OAI bc I’m curious if this new family of I-6T engines dilutes and how they hold up.

2 more OCIs of VRP in my TSX to go then switching over to either HPL Euro 5W30 or Supercar 0W30…..yeah, I acknowledge either choice is wayyyyy overkill for my daily driver purposes but I like the idea and love supporting their business.

I would probably buy some 0w-20 premium if I could find it in a local store at a sane price, there is no question it is a fine product line

15% off with code BITOG15 which usually absorbs shipping costs. I’m not aware of them selling at retail stores.

It’s a split for me. NO VII oil and CK-4 HDEO HPL
