Even on LPG, the engines get dirty and the oil becomes black ... But much less than gasoline, and do not talk about diesel ...
It is true that on a new LPG car, the oil is transparent as the first day when we do the oil changes.
I don't really notice this: the oil is "slightly" browned on my C1 which is close to 100 km or on my C000 which exceeds 5.
But indeed, the color is only the reflection of the "particles" collected.
The "molecules" still end up being crushed and the lubricating power decreases. This is why I respect the recommended intervals ...
So I keep driving the LPG and eco-driving as much as possible. A mlotr, I would say. If I'm still here, I'll tell you the mileage achieved (my C5 will probably die before the hour because it does not roll enough, I keep it as others have a motorhome, it happens to me, when I baroude, to sleep in - I just got home!)
I am not convinced that all the effects attributed to eco-driving are varied:
- the mishap does not prevent a little more serious braking from time to time: a stop down a hill at home; unexpected exit of a vehicle; fire turns red when we are at 50 m ...
- eco-driving does not mean "cold engine"; the aquastat will stabilize the engine at the same temperature as in normal driving; Admittedly, an engine that is going to "hum" will chuaff more at the level of the heads of pistons / cylinders; it's clear ; However, when I ream my hill, the one where there is the stop, I pull my 5th around 2 rpm, the engine also heats up because there, I request almost full power ...
I find that we are here attributing questionable things to eco-driving. Christophe, I am not at all sure that your records would not have warped in normal driving! My first hypothesis in your case and your climate indeed seems to me to be the "rust spots" at each slightly prolonged stop (2 days), after a good salting of the roads and a good penetrating fog ... [it happens, for example with you, it seems to me; I know the area a bit - I remind you that Christophe lives in the Belgian Ardennes and not in Alsace!]
