The last owner ran this car with a mixture of 20% vo to 80% disel Iam not going to use vo this winter in this car, however next summer i intend to run this can on 50 vo and 50 disel is this a good ideal t> this car was owned by an elderly gentleman and it has 150,000 KM Did I get a good buy. I have been driving this car for 3 months and I have had no problems everything workd except the AC I was wondering what kind of mileage I should get per galloni from this car if I disconnect the AC belt will it help with miles per gallon thank you for any help and advise disel boy

I dont know anything about VO.

If your AC clutch is working correctly you will not see much of an improvement from removing the belt (0.1 mpg or less I would think). If the AC system is shot and you do not intend to fix it go ahead and pull the belt.
