Motul tech says group 3+ on phone conversation

[GI_GRIFF]

Can someone tell me what the difference is between group 3+ and group just Group 3? The Motul tech guy said their 8100 series is group 3+ base stocks

Not an exact classification - indicates more severe cracking for tracking that It’s closer to higher group performance …

Motul says many things and after need to fix it's words and advertising like in Germany.
Depend on which 8100, basically not, most 8100 are good G3 with little G3+ sometimes.

It’s not an official designation but some will unofficially call GTL base oils group 3+ since they are closer in performance to that of a PAO base oil.

They drop some ester content in it. But they are not using GTL for example which many like to call Group 3+.
They use very good Group III though.

"Group III+ advantages over conventional Group III are that it offers lower cold cranking simulator (CCS) viscosity and Noack volatility, better pour point and oxidative stability and can be a partial or full alternative to PAO in some applications.1"

As already noted, a marketing term just like Chevron’s Group II+ base stocks. It doesn’t designate anything new (only the API could do that) since the performance still falls within the limits of the current API designation for the Group.
