Want to start a thread off with people posting about what BP stations give away what when you put in more than 100l of fuel:
A63 Westbound at North Cave: Free Hot Drink.
A1 Southbound north of Newark: Bag of sweets including giant KitKat, bag of Crisps, polos.
Strensham Services, M5 South: Voucher for Moto Fresh Express restaurant - £3.99 for any hot meal plus hot drink.
Conor, I think you must mean Strensham on the M5 South - probably just a slip of the keyboard

LOL, yeah. Edited now thanks. Only ran there for a trailer swap every night for 2 weeks last month.

Same as Great Heckington Eastbound on the A17,near Boston.Or it was the last time I filled up there last year.

BP Grantham, (Tony,s) a handful of Moto vouchers
Newbury services, likewise
I thought all the BPs on a Moto services gave you 50p or £1 vouchers when you bought fuel. The Hilton Park vouchers used to be only usable there, but every where else they were Moto vouchers, usable anywhere.
The £3.99 meal vouchers were there for the asking, you didn’t need to buy fuel to get them. They might want some easy proof you are really a truck driver though, and if you’ve just put 300l of diesel into your tank, how much more proof would they need

Im sure that you only get a quid for every 100 litres, but at Grantham and Newbury they seem more generous 
I think the Hilton park scheme was a good one, and it was the only services that I would eat in. the drivers restaurant used to be decent food.
i know its off thread a little but if you get your tank cleaned at tank-clean at stockton (just off the a19 flyover) you get a £1 argos voucher
When abroad I try to fill up in France at BP sites as they still give points onto a card. You can redeem these points for loads of different items from a catalogue.

I use a Shell Eurocard but Toddington services which are BP have one Shell pump and I get Moto vouchers in addition to the points on my Shell pluspoints card. Also, Woodhall services (not BP) are giving vouchers for KFC or Burger King when you get more than 100 litres.
