Mishnayos Menachos Perek 9 Mishnah 4

Many animal offerings are brought together with a meal offering and a wine libation. These additions are collectively referred to as libations. One may mix together the libations of bulls with the libations of rams; the meal offerings may be mixed as they both share the same ratio of flour to oil, i.e., two log of oil for each tenth of an ephah of flour. Likewise, one may mix together the libations of lambs with the libations of other lambs, as the meal offerings both share the same ratio of three log of oil for each tenth of an ephah of flour. And one may mix together the libations of the offering of an individual with those of a communal offering. And one may mix together the libations of an offering brought on one day with those of the day before, if the meal offerings have the same ratio of oil to flour. But one may not mix together the libations of lambs with the libations of bulls or the libations of rams, as the meal offerings have different ratios of oil to flour. And nevertheless, if one intermingled the flour and oil of these lamb offerings by themselves and the flour and oil of these bull or ram offerings by themselves, and only then were they mixed together, then they remain fit to be sacrificed. If they were mixed together before the oil and flour of each offering were independently intermingled to form the meal offering, then they are disqualified. With regard to the lamb offering that comes with the omer meal offering, which is accompanied by another meal offering and a wine libation, even though the quantity of flour used in its meal offering is doubled, i.e., one uses twice the amount that is generally used for meal offerings that accompany the sacrifice of a lamb, its oil and wine libations were not doubled; rather, three log of oil and three log of wine were used, per the standard quantities used for a lamb.
