Fellow "oil guru's".....from my many years of studying things online "oil related" and such on forums like this...I have one underlying question for you all? From what I understand about engines, and oil consumption related to piston rings..etc..it seems that while any engine is under a large "load" or being worked hard..that the force of combustion is supposed to force the rings against the cylinder walls with "greater" force than such an engine that is under a light load or idleing, and in turn "seal" better from the heat of the combustion?....I personally am referring to a duramax engine, and as I have noticed personally a greater amount of oil consumption while towing heavily in summer months..NO matter what brand or weight of oil used..whether it was synthetic or not! I can run say 7,000 miles or so unloaded compared to the same mileage (not completely loaded the whole time but worked hard by towing) but notice more consumption while working hard. Do any of you feel that the oil is being "evaporated" so to speak this much? Or do you believe it is getting burned up by passing by the rings? Give me your insight on this matter. Thank you all in advance!
