well spring is here and i believe i need a new bottle of after run oil i been hearing people use marvel mystery oil for air tool but i don't think i have that near me....
so can any high grade air tool or compressor lubricant work for my savage engine?

this is one of em

LUBRICANT, AIR TOOL 500ML SYNTHETIC - this is 13 dollars and is synthetic is i think its safe on the o rings

Overview

Extreme Temperature Synthetic Air Tool Lubricant

* - Lubricates and protects pneumatic tools
subjected to extreme temperatures varying from
-55°C (-67°F) to 250°C (482°F)
* - Protects tools in heavy-duty applications where
the work could overheat the tool
* - Reduces wear, prolonging tool life plus reducing
maintenance costs
* - Prevents rust and dissolves sludges and
deposits typical in compressed air systems
* - Can be applied with conventional air line
lubricators, as well as applied into the air tool's
air inlet
* - Synthetic composition maintains its viscosity
even in extreme temperatures
* - ISO 32 viscosity index
* - Non-detergent
* - Has convenient "flip-up" pour tops
* - All air tools, air valves, air cylinders and air
motors requiring oil lubrication
* - Temperature range -67 °F to 482 °F (-55 °C to
250 °C)
* - 500 mL
this is pretty cheap compare to hobby grade ARO and has some what the same propertys like prevent rust and dissolve sludge and lube...
thanks in advance

It could be O.K.
You could also just run with SIDEWINDER fuel, you dont need After Run Oil because its already got something in the fuel to protect your engine from rust and grunge.[8D]

I agree that is reason why I run SIdewinder race blend 20% with 12% oil, no after run oil needed and it tunes great!!

my hobby store doesn't sell that only blue thunder and tornado
but personally i like to add after run oil... but they are expensive

I personally don't like Blue Thunder or Tornado! You can buy Online cheaper than in LHS anyway! There is a thread started on which nitro is best by the way, just do a search! If I can find it i will paste it here for you!

hope it helps!
P.S. Everything I have ever heard is that Byron's gen2 is best then Maxy's, then you could choose Sidewinder,Nitrotane, etc, etc!

If you want to add after run oil then do it, like I said before, Sidewinder does'nt need it but if your using something else, sure go ahead.
If it is really wet and muddy at the track then it cannt do any harm to protect your engine after a damp race, but, be carefull of what you use.[8D]
