What oil is best? and what ratio?

[Nitehawk55]

Shindaiwa is the older stuff, now it's labeled Echo. Maybe their selling older stock at a reduced price.

Who told you that ?

Who told you that ?

Their the same as MSDS is the same. Not sure about the new label and that SDS that we saw?

Its the exact same oil, just labeled Echo now.

 

[KenJax Tree]

Who told you that ?

I pretty much figured it out when it was all labeled Shindaiwa a few years ago and now its labeled Echo.

Doesnt Echo own Shindaiwa now?

Yup and they slapped their name on the better oil and kept Shindaiwa's name on ONE.

https://en.wikipedia.org/wiki/Viscosity

The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.[1] For liquids, it corresponds to the informal concept of "thickness"; for example, honey has a much higher viscosity than water.[2]

Viscosity is a property of the fluid which opposes the relative motion between the two surfaces of the fluid in a fluid that are moving at different velocities. When the fluid is forced through a tube, the particles which compose the fluid generally move more quickly near the tube's axis and more slowly near its walls; therefore some stress (such as a pressure difference between the two ends of the tube) is needed to overcome the friction between particle layers to keep the fluid moving. For a given velocity pattern, the stress required is proportional to the fluid's viscosity.

A fluid that has no resistance to shear stress is known as an ideal or inviscid fluid. Zero viscosity is observed only at very low temperatures in superfluids. Otherwise, all fluids have positive viscosity, and are technically said to be viscous or viscid. In common parlance, however, a liquid is said to be viscous if its viscosity is substantially greater than that of water, and may be described as mobile if the viscosity is noticeably less than water. A fluid with a relatively high viscosity, such as pitch, may appear to be a solid.

Yes, all correct. However, as it pertains to hydrocarbons as viscosity goes up so does density, BTU content, and the temperature at which point the fluid burns completely.

With a high viscosity oil wouldnt using a higher ratio or less oil aid combustion?

It does to a point.

My local dealer has lost his mind. Echo RA 6x6.4oz is 28.80$ + tax!!!!! I can order 129oz for 63$

Ben what would u consider prime range on the viscosity for saws, (firewood), trimmers, blowers, ope in general? How about milling?

I don't use viscosity when judging the suitability of an oil.

Ouch!

Dang pig rich saws . Slipped on the oil slobber on the floor again.

Compare the viscosity and BTU of #1,#2,#6 diesel and bunker "C" would show what I am saying is true.

I thought over $20 was high!

 

[Keith Gandy]

I thought over $20 was high!

Glad I bought a pile when it worked out to 12.53 qt

 

[jk14]

I got some 6.4 oz. bottles of RA a few weeks ago at my local dealer for $2.50 each. Seemed pike a pretty good deal so I grabbed a six pack for $15+tax.

 

[danimal]

amsoil dominator retails for 12 buks a qt.
my buddy-dealer gets 8 buks for it at the door.

Mine's free He just bought a case of qts for me, not sure what I'm gonna do wiff 12 qts....
