Hi,
I wonder if anybody could share their experience / knowledge. I have a 3-year-plus old Paj NP petrol auto, bought new, and have only done 35000km so far. It developed pinging even only when pushed a liiitle harder. 2 garages told all computer tests on the engine returned correct measurements. One garage recommended me to "rev" it up more.
I sort of understand maybe the car (and engine) has had a very easy life. No offroading
home office drive, with no major traffic jam. It is always serviced on time, correct tire pressures, fuel from the likes of BP, Shell etc. On fuel I started with ULP but have gone PULP over the last year or two.
Now the questions after the long intro :
1) This is the first time I've been told of carbon build-up after just 35000km in 3 years. Nevertheless I do rev up more, i.e. accelerate faster (within the law
). Any comments? Does this make sense?
2) I purchased one of those engine build-up "cleaning" agent and maybe subjective but I've notice improvements (i.e. reduced pinging) only after a couple of days. Does anybody have experience with these additives? Do they really work?
Thanks heaps for anybody who could help sharing their thoughts.
Best regards,
Jonathan
