Tes 668 vs Dexron 6

[rotoscrew]

I am currently running Dexron 6 in a Quincy rotoscrew air compressor would there be any advantage to running Tes668 ?
any input would be appreciated.

TES668 @ 100*C is about 7.0 cSt viscosity
Dexron6 @ 100*C is about 6.0 cSt viscosity
so there's that

I don’t think 668 would run any better than Dexron 6.

Probably worth it to look at an actual formulated air compressor oil though. Lots of options for probably similar price.

It appears that the requirements are for a 30 grade/ISO 100 oil.

A 30 grade/ISO 100 oil is NOT equivalent to Dexron VI or Tes668. What grade/ISO fluid does your compressor manual state?

I would contact HPL, Amsoil, or Schaffer's directly and let them know your specific compressor model and what they recommend.

For example:

You probably want to reference this page from Quincy. It says that screw type compressors come filled with their QuinSyn Plus fluid which is described as a "synthetic hydrocarbon/ester fluid." Dexron VI is not the same as it does not meet the flash point, plus it has a lot lower viscosity at both 40c and 100c.

Interesting, the data I saw said it had a Group III base oil with only a defoamer and minimal anti-wear additives.

The only thing in common with ATF and the oil ripcord showed is that the 100C viscosities are very similar with an ~ ISO 46 viscosity.

Their fluids are made by Lubrizol.
