Why Not Detergent Oil In a Barber Chair

Several posts?

Where?

Why would you question those posts?

Yes, "several" sites I searched also suggested non-detergent 30W oil.

Knowing nothing about the seal materials used in barber chairs, why would you question several posts which recommend not using detergent oil.

I don't.

As Lyn indicated, the problem will be the seals damaged by the detergent additives.

Thanks Ignator. Appreciate the straight up answer.

but how will he flush out all the by-products of combustion suspended in the oil?

Because you're supposed to use shampoo oil--detergent is too harsh.

If the chair has any brass parts in contact with the oil,the high zinc content of H D oil could cause abnormal wear.Also the old seals were probably leather,which can be softened by the detergents and lose sealing ability.

those old chairs have a lot of mileage on them. perhaps high mileage oil would be best

I have seen "Oilite"sleeve bearings clogged by high detergent oil,resulting in lack of lubrication and bearing failure.

These bearings are made of bronze or brass powder that is compressed into a bearing shape.

The gaps between the particles become a reservoir for oil to lube the bearings.

Whithout these open pores,the oil cannot reach the inner surface of the bearing.

Non-detergent oil is not hard to find, so where's the problem?

Or are you just curious about why they specify non-detergent oil?

If so,perhaps I have answered some of your questions.

Most auto parts stores will have hydraulic jack oil, it might be a better choice.

On sea platforms they use canola for hydraulic oil to minimize environmental contamination.

Really?

.

Is canola oil use as a hydraulic fluid on sea platforms limited to barber chairs? or are there other places as well?

I wonder if there are any figures available to support this claim...kind of sounds like oil firm PR departments working overtime, attempting to convince people they deserve an f'ing cookie or something, rather than something that make a big difference.

Was this practice pioneered on the Deepwater Horizon?

Thin ice! Proof it or die (Do Indepth Examination)!

I believe there is some mix up here. That that should be an ISO 32 grade oil. A hydraulic oil. ISO 32 grade is about a 10 w oil. Knowledge of pump jacks in which the pump and the displacement cylinder of a barber chair are similar. A 30 w motor oil oil has a viscosity too high to flow properly into the pump. And if we are talking a 30 w motor oil the viscosity my be even higher. As the oil is formulate to work under elevated temperature. The detergents in motor oils and those in hydraulic oil differ. Those detergents in motor may degrade the hydraulic seals.

If you can't find a 10 w hydraulic oil. Automatic Transmission fluid would be a better replacement.

Also I also have seen vegetable oil used in hydraulic systems. Wouldn't recommend it. Vegetable oils are made of many different fats and oil extracted from the plant. Some of which will evaporate over time which will leave fats that gel and form solids. These solids will contaminate seals and block ports.
