My reply included "thoughts" and answered the general concept of using air tool oil as an alternative to oil additives.
Marvel Mystery Oil and Marvel Air Tool Oil, which is used in Pneumatic air tools, have exactly the same primary ingredients as shown by the MSDS.
My reply answered the general concept of using air tool oil as an alternative to oil additives.
The OP asked about a specific air tool oil which isn't from Marvel.
How does posting MSDS information from Marvel Mystery Oil and Marvel Air Tool Oil help the OP decide when asking specifically about Sta-Lube brand air tool oil from CRC Industries?
If you ask for help with a specific Chevrolet EGR problem and I post repair information for a Toyota, is that helpful? In general, they're both cars!
To the OP, I think Clevy posted some excellent information in post #2 for you.
I'll also attempt to help you out by posting the ingredients from the CRC Industries Sta-Lube Air Tool Oil MSDS:
Code:
COMPONENT CAS NUMBER % by Wt.
Hydrotreated light naphthenic distillates 64742-53-6 93 – 97
Solvent-refined heavy naphthenic distillates 64741-96-4 1 – 5
Zinc, dithiophosphate di-C1-14-alkyl esters 68649-42-3 < 1
Less than 1% ZDDP by weight (but we can assume they meant mass) means you're not getting much for your money.
The Edelbrock 1074 Zinc additive says this:
Code:
Components CASNR Amount(%)
Synthetic Hydrocarbons 68037-01-4, 64741-97-5 20-60
Molybdenum compounds 71342-89-7 5-20
Phosphorus compounds N/A "Mixtures" 5-20
We can safely assume that it means % by mass, which means it has at least 5x as much ZDDP "phosphorous compounds" as the Sta-Lube air tool oil... and it's designed to be put in your motor oil. It also contains a similar amount of Moly compounds which can be an excellent anti-wear additive.
That being said I would not use MMO, Marvel Air Tool Oil, Sta-Lube air tool oil, Edelbrock 1074 Zinc additive or anything else in a "hot rod running a solid lifter cam with higher than stock spring pressure". I would use Shell Rotella T5 10w30 or T6 5w40. Or if your pockets are deep, one of the purpose built "hot rod" oils from the boutique blenders.
Now this is the kind of intelligent discussion I hoped to have, not snide remarks or rude comments. Thank you for the product details. I was never going to put air tool oil in an engine, it's far easier to buy quality oil right across the road. I recommended both Rotella and Valvoline VR-1 to my friend, but with only a few miles on his oil change and fresh engine, he decided to use the additive this OCI.
