Italian Tune up
« on: February 25, 2019, 11:02:02 PM »
Has anyone here done an Italian tune-up on there 1.4 petrol? If so did it help in any bit with power restore and or fuel/oil consumption? My '04 mazda 3 petrol is going through a bit more oil than I'd like (odometer is 157000) and I read a tune-up may help with carbon build up by burning it off? Curious  :)

While I do like an Italian tune up, I don't think it'll help, may hurt the car further in this case.

A 1.4 is a small engine for a 3 so it will have worked hard for a living. 157000 miles is a long way for a small engine. If you have no external leaks oil consumption would be pointing to internal engine wear on piston rings or valve stem seals. If you haven't got a blue plume at cold start and it's not failing the MOT on HC then it's a probably a case of keeping the oil topped up and monitoring it until something bad happens. Which could be years away so nothing particularly scary unless it's literally using litres of oil every 1000 miles.

I feel as though what you likely have is an engine in its old age, driving it hard could make it worse. You'd likely need a teardown and replace worn parts to fix it but it's a case of if it's worth it.

Thanks for reply, phew thank goodness I asked was going to do it and see if it helped ;). Just did a service 2 days ago and changed oil from 10W40 to 5W30 as it is the recommended oil on all the oil selector websites, so will monitor it and gauge the level of consumption. The car is mainly my wife's run around so is doing it's job very nicely so really cannot complain on its reliability no blue smoke or any visible indications that it is consuming oil. Just keep it topped up and drive on I guess. Thanks

It's unlikely you'd have gone out and killed it dead, chances are it slowly get worse over time until it is actually a problem.

But putting a lot a lot of stress on it probably not the best idea either.
