19.5% TPM
Dark-looking oil can still measure below the trial's TPM change point.

4 Simple Steps
Follow these steps at the end of each frying day.
1
Add Purimax
Bring the oil to approximately 350°F. Add the correct daily amount of Purimax directly to the oil.
2 Scoops
40–50 lb Fryer
4 Scoops
80–100 lb Fryer
2
Mix Thoroughly
Stir Purimax into the oil for approximately 5–10 seconds, making sure the powder is evenly distributed throughout the fryer.
3
Begin Filtration
Drain the oil into the built-in filtration system.
If your normal procedure includes circulating the oil through the filter for approximately 2–10 minutes, continue doing so. The longer the better. If your fryer normally filters and immediately returns the oil, that is also acceptable.
4
Return the Oil
Once filtration is complete, pump the filtered oil back into the fryer according to the fryer’s normal operating procedure.
Optional Tip
Mid-Day Filtration
If you normally perform a mid-day filtration, you may leave the Purimax powder on the filter paper from the previous night and use that same filter during the next day’s mid-day filtration cycle.
Replace the filter paper afterward according to your normal schedule.
How to Judge Your Fryer Oil
Dark-looking oil is not automatically spent. Judge oil by more than its color to understand how long it remains usable during your Purimax trial.
01 / Visual evaluation
Look Beyond the Color
These observations can indicate that dark-looking oil may still be usable, but none is a pass/fail test on its own.
- Surface bubbles are still present.
- Burners or heating elements can still be seen through the oil.
- The oil appears red or amber rather than completely opaque.
Use a Ladle Test
Oil looks darker in a deep fryer because of its depth. Scoop a small amount into a clean stainless-steel ladle or shallow container. Check its true color and clarity under good lighting.
Do Not Use Color Alone
Judge the oil using clarity, frying performance, smell, finished-food quality and TPM (total polar materials) when available.

TPM + Daily Trial Check
When a TPM meter is available, it adds an objective measurement to your daily oil evaluation. The examples below show TPM readings from two separate oil cycles.
14.6% TPM
Oil color can change well before TPM reaches the replacement range.

23–24% TPM
For this trial, the guide uses 23–24% TPM as the upper change point, unless your restaurant's standards or local requirements call for an earlier change. Replace oil sooner whenever quality or safety checks warrant it.
