They didn't, just said that they have to follow the service schedule. Just seems mad in this day and age, when we are trying to stop waste and creating more rubbish. When I first started driving and looking after my own cars back in the 70's, you would change the oil every 3000 to 6000 miles due to it being mineral oil, but now with fully synthetic oil, in real terms it could be done by the mileage travelled. To be honest even doing less than a few 1000 mile a year, I'd probably still change it, but it should be good for 2 years with really low mileage.
Same for air filters and pollen filters etc, why change them just down to age, when the car hasn't travelled sufficient miles to get them dirty... Its becoming more and more of an environmental thing and I'm surprised Lexus hasn't already jumped on this, let alone other manufacturer's, but its a good source of great income for them I guess.
