Modern GDI don't have this problem already or no where as severe as the Peugeot / VW GDIs of old. I drive a relatively newer Peugeot, 160k mileage with no walnut blasting done. If you really want to know whether there is severe carbon build-up, get the workshop to open up the valve cover and look at the valves, pistons etc. ayamtriplex liked this post

QUOTE(littlefire @ Aug 13 2024, 09:26 AM) This depends, like someone said if he got a lot of start stop or short distance driving the chance of getting carbon built up is high. My mechanic place have seen Mazda Cx5 with over 200k still no issue as the owner always travel on highway high-speed driving, while another customer with 100k over already complain jerking and serious carbon built up, when ask he say he only drive in city and never really drive high speed over 110km/h Open up the engine top can see already whether walnut blasting is required or not, you can decide after looking at the carbon build-up. Anyway, nowadays its not too expensive do this, below RM1k I think. The one that pampered the ride is the worse, compare to another 1 which is speed devil got less carbon built up.  |
