Someone once posted here to keep deposits from building up the car should be driven hard. I have an 05 Cooper convertible. Once or twice a month I drive to my nieces so my car spends 150 miles at 80-85mph. Every three months or so I toss in a can of Chevron fuel system cleaner or equivalent. Is that a sufficient 'tune-up?'

 

i just beat the **** out of my car on a daily basis and that seems to do it for me ;p

The 'Italian Tune Up' was more of a thing with carbureted motors before electronic fuel trim monitoring. I'm sure you could burn a little of the build-up on the piston tops if you 'Ike Turnered' your car, but a conventional tune up would yield better results.

 

I use the 'Italian Tune Up' to keep my spleen running smoothly. For everything else it's top tier fuel and an occasional can of BG 44K.
