I totally agree but the oil companies will battle you to the very end in disagreement. Engines from the 50's and 60's were ready for a rebuild by 60K to 70K...today, they are barely broken in at that mileage. Oil from that era ended up as sludge, caking the heads and gunking up the oil pan.

Sadly, it will probably take another generation to get the 3K oil change myth out of peoples heads. If the U.S. is to ever break the hold that the oil companies have put us in, we have to stop the useless waste. It amazes me that they want us to think the oil is many times better...but lasts many times less...and that auto manufacturers have not improved filtering technology beyond the early 1900's.

I believed the hype as well, changing my oil every 3K for years. The only thing that did was put my hard earned money in the hands of laughing oil company execs. I probably still change my oil too often in a 99' Ram with 148K...3 times a year or around 8K. Still do not have to add oil between changes and heads/pan are as clean as new.
