Use 22% methanol by volume ratio instead of 20% and process it like normal, your yield will be about 85%. The only other thing you can try is blend it with a lower titrating oil or add some glycol from a previous batch to bring the titration numbers down.
We are using KOH. We are also looking @ mixing with less acidic oils, but right now this is the only source that we have. Never thought about adding glycerol from a previous batch, might be something to look at. We were thinking of using 22% methanol also.

I use 25% methanol and process for ~ 90 minutes. always passes the 3/27 test.
It is reassuring that you are using oil that titrates that high also. The other place that we want to get oil from titrates @ 1.7 mg / ml, but he is locked into a contract until April.
