AIBU - splitting petrol costs

[ZanyMobster]

DH, my brother and I disagree on how petrol costs should be split between families. I will drip feed slightly as I think if I put the full history it will skew the answers a bit (nothing huge but just a slight omission) but I will post again after a few answers.

Scenario - 2 adults and a child from one family and 1 adult and a child from another family travelling in a car.

Option 1 - split 5 ways and charge per person
Option 2 - split 3 ways between the 3 adults
Option 3 - split in half, half each per family.

I am guessing no way is absolutely correct (and I totally get that it is a minor problem either way) but I would really appreciate your views. Thanks.

There seem to be a lot of people responding, without reading all the OP's posts.

Yes, as a rule, most people will just give lifts to family and friends and not expect petrol
Yes, if you were going somewhere anyway, then no issues about someone jumping in.
Yes, if all other things were equal it would make sense to take turns to drive.

However OP has explained why it isn't the case here, if people bother to read her posts.

OP's dh and brother are doing a lot of regular, long journeys. They decided that this 'hobby' was affordable, if they travel together and split costs. For logistical reasons, OP's dh has to drive most of the time.

In that context the question is, should one of the adults then pay more, because, on the one occasion, his son also gets in the car.

I'd say no, OP. Your dh and brother should halve the petrol each time, and your brother should also pay any parking, or get the coffees in on top, to thank your dh for doing all the driving (and wear and tear / mileage on the car). Whether son / nephew is in the car is irrelevant.

Thanks Backforgood - I was thinking I was going to stop responding to those comments as I felt I was just saying the same thing over and over again and was getting irritated. We will definitely just do 50/50 in future to avoid any issues and of course will continue doing the usual family favours etc at other times.

Tbh, OP, I actually think your db is fully aware of costs and is frankly taking the piss. Who goes out for a meal with no means of paying? My default is last minute check, fags, purse, phone, keys. Stop enabling him.

I couldn't be bothered splitting petrol with the people I travel we. Usually the non driver will buy drinks/shout dinner and it all balances out in the end anyway.

50/50 I think. Although, five years ago my brother took £100 from me for a 220 mile round trip when my youngest had to go for a hospital appointment. He's as tight as a ducks arse though...

Minute, please read the thread, this has been explained several times.

Maelstrop- yes I do agree that it's partly our fault by enabling him.

Kate - I couldn't imagine doing that to family, how awful.

I wouldn’t even bother splitting it with family. It all evens out in the long run.

Seriously Joinourclub, have you actually read the thread or are you being sarcastic? I have explained way too many times why this doesn't work.
