I was just reading about modern DI engines having issues with excessive deposits forming on the valves in relatively low mileage engines .. Recommendations from companies like VW to regularly run engines at 4000rpm for extended periods to burn off the deposits .. Hyundai recommending regular engine cleaning treatments? First I've heard of this. Sounds a bit counter-productive for modern cars which are basically a black-box, don't touch, consumer appliance?
I'm assuming this is probably a bit more of a problem relating to people driving cars for short distances at low speeds; I.e. the daily commute. But seems that the people who buy cars like DIs or diesels are the most likely to drive like this .. And these engines seem the least suitable to their driving needs? |
