Turbine oil difference
 

Does anyone know what the difference is between Mobile Jet oil two (mil-prf-23699) and Aero Shell (mil-prf-23699F)

The only difference in the mil specs is the f at the end in the Aero shell.

Just wondering if one can be substituted for the other. I am thinking Jet Cat.

Thanks

I am no expert but both oils are fine to use. Somebody will correct if I'm wrong any approved full scale turbine oil is acceptable for our use.

The specs look almost the same. A friend of mine that works at Shell says the two are most identical.

I use Mobile II turbine oil for my turbine.

JetCat OK both oils, but I prefer Mobil Jet II

Thanks Guy's,

I thought so but could not figure out what the F stands for. Google could not help me.

Having worked at Pratt & Whitney for many years (now retired) I spent some time working with the engine lube systems, including qualifying the oils for use in specific P&W engines. The 'F' in the mil spec is simply specifying the spec revision. You can be sure that Mobil Jet II is up to the latest spec as well as Aero Shell 500 and 560. I cannot recall an oil that we tested, that was certified to the Mil spec, that did not also meet the P&W spec and get accepted for use in the engines I worked on.

Use Mobil DTE lite. It's $5 qt vs $15 qt. I have been running it in my motors for quite a while with no problems.

DTE light for me too.

It's strange how many jet flyers won't touch an oil unless it has the word 'jet' on the label.

We are not using 'jet' oil anything like the manufacturer intended, in fact the manufacturers
would probably advise against it's use in our application.

We are really using it in a two stroke like total loss application. - John.

Besides DTE light you can also use Pacemaker T32 from Citco.. it is the EXACT same as Mobile DTE Light. I know 2 other ppl running it in their turbine with no problems what so ever. 1/2 the price as DTE light as well: $90/5gal to $45/5gal. Soon as I finish my DTE light im running it in my jetcentrals'.

Boomer, not many guys over here using turbine oil. Most of us are using TCW3 spec 2 stroke oil at no more than 2%, heaps cheaper and works VERY well. Turbine oil is carcinogenic and not designed to be burnt, beats me why some people insist on using it.

Does anyone know if DTE Light is available in gallon jugs? A 5 gallon pail is inconvenient and would last me several years.

I have found DTE 24 in gallon jugs. Although similar I don't think it's exactly the same as DTE Light.

Dreamworks has DTE listed in 1 gallon jugs. $22.50 I think.

Its a guy thing!

Something that says "jet" on it is WAY more cool than something that doesnt.

Just like electronic things... something with blue LED lights is more cool than green or red LED lights.

That's not DTE Light. That's "DTE 24 Hydraulic Oil". The stuff recommended for turbines is "DTE LIGHT Circulating Oil".

It gets confusing because Mobil uses the terms Light, Medium, and Heavy to indicate viscosity ranges for a number of their products.

Click on the following to see Mobil's Product Data Sheets:

"DTE 24" is one of their DTE 20 Series Hydraulic Oils, which is recommended for hydraulic equipment:

"DTE Light" is one of their DTE Named Series Circulating Oils, which is recommended for turbine applications:
http://www.mobil.com/USA-English/Lub...DTE_Named.aspx

The specs are similar and the hydraulic oil may work, but I'm looking for the stuff that's recommended for turbine applications. I'll have to check with McMaster-Carr since they are the only ones that show it available in gallon jugs.
