My Hilux with a 22r in it is guzzling a fair bit more than it should and I'm about to head off on a roadtrip in a couple of months so I definitely need to sort it out. I'm wondering what are the best things I can do to get her a bit more efficient. I'm getting a webber carby and new radiator (previous owner put stop leak in there

). Does anybody here have some suggestions?
cheers
