Just had 3 year/ 37500 miles service carried out on my 2011 jazz, car is just 3 years old with 27000 miles on clock.
On checking the job sheet I noticed the spark plugs had not been changed, service manager pointed out that this model jazz is fitted with long life plugs, and will not need a change until 70000 miles!
I would be interested in what other members think of long life plugs. My only experience of them to date has not been good,although not in a Honda engine . I have had them on 3 previous VW s, and was not impressed! None of the sets of so called long life plugs lasted much longer than standard plugs. The VW dealers assured me that the long lifers were good for double the mileage of standard plugs. I did not find this to be true, with progressive bad starting and general sub standard performance which was cured strait away with new plugs.
70000 miles on a set of plugs does seem a bit optimistic to me, or am I being a bit pessimistic?
