I understand that modern oil is different than the stuff back in the year I was born. I understand that they really might be able to last longer. My question is what is wrong with changing oil early. I have seen comments from some saying that you are causing damage by changing too often. How is this possible?
To the OP, I'm a 2500 mile or 3 months (whichever comes first) guy.
I knew someone would ask that question, which is why I left that open.
But that's okay, an inquiring mind is wonderful and shows intelligence!
Metal-to-metal wear causes more engine wear than at any other time. When the oil is drained from an engine, (changed), the oiling system loses all oil pressure and when the engine is started metal-to-metal wear is briefly occurring that is shortening an engine's life and also reducing the engine's ability to run, "like new", i.e. reduced power, fuel economy etc. caused by increased engine wear. On top of this, changing engine oil too often is very hard on the wallet, (long term), and also very hard on the environment. Also, I think it might be that the Big Oil industry is vacuuming our wallets empty quite enough with the ridiculous gas prices they are gouging us with!
Personally, it turns my stomach to be donating my hard earned money to them in the first place, (with their record profits
), than to also have motorists handing over their hard earned cash for unnecessary oil changes as well!
The 3,000 mile oil change was originally for vehicles in the 1960's
, but thankfully that was over fifty years ago
now and technology has greatly progressed from the comparative stone age era of the 1960's. I've done countless oil analysis tests on used motor oils in the past 25+ years of my automotive industry career and the results have all conclusively proven over and over again that the 3,000 mile oil drain interval belongs on the ash heap of history.
