Tell your husband the manual of the 22 says 87 octane can be used. I am on a trip now and only use 87 octane gas and have no problems. I have been able to find 87 octane gas for less than $3.00 a gallon in KY.This has got my husband really bugged! Hoping to buy a 2022 Envision Essence, AWD, as soon as we can find one. I told him we might have to use 91 octane (highest available where we live) and he is pitching a fit. I asked him to compromise at 89 octane. Jury is still out if he'll compromise. Thoughts anyone?
