I don't know about oil gages, but the gas gage in 1934 - 1936 Auburns used red manometer fluid. The temperature gage used a type of dyed either. If you need manometer fluid that does not turn clear, give me a call 715-262-3183
The bitterness of poor quality remains long after the sweetness of low price is forgotten.
