You risk flat spotting your tires. Look at the sidewall for the maximum pressure allowed for the tire and inflate to a few PSI below that pressure, or buy a set of these:

By far the best thing is for someone you know and trust to take the car for a reasonably fast, 20 mile run every two weeks with the aircon on to move the suspended lubricating oil around and keep the system's seals sound.

Perhaps we could organise a rota of car caretakers for the OP from members on here!?!

Of course you can get to the battery by yourself.

It's not that hard: you just need the right tool [which is easily acquired] to undo the two floor bolts to hinge the seat back but I see you have a T3!

Here's the how-to - it's a very easy ten minute job on T1s and T2s.

There are different opinions on the T3 as to whether or not the seat still hinges [electric seats may be different] so you can check this out on yours:

If your car catches fire and burns the building down . . . or it gets stolen . . .

Keep the car insurance going regardless!!

when parking the car, mixed with a full tank?

The normal method, when using any fuel additive, is to pour it into a relatively low tank just before you fill it up so the movement of the fuel going into the tank mixes it up along with the movement of the car when you drive off the forecourt.
