Yeah,that injector service is revenue raising for the dealer(costs them next to nothing).On my previous car (Subaru Liberty)they tried to hit me with that at 20k!!WTF.A good friend is an ex Subaru SM and he told me you shouldn't need injector service before 100k.or unless you have an injector problem.some dealers will try anything to extract more money out of you.Tell them BEFORE you leave your car for service NO additives at all if HA doesn't include it as part of the service you don't want it.I've had bad experiences with this sort of thing before and it really pisses me off.
