Before disposing of your old fluids, ask yourself this: Is this stuff any good?
Newer motor oil has less zinc, better for emissions? But I've read about sooo many folks who did a cam swap only to (surprise!) have a failure. I've had many transmission guys tell me that the old stuff will still be good, and that it's actually BETTER than the newer stuff. Think about it - with all the differnt alloys and what not, I'm sure that they've tweaked the friction co-efficient and more. Manual transmissions use ATF now, almost unheard of 30 years ago. I'm not sure that it'd be wise to use the old stuff in a new car, but seeing as I don't have one... I'd love to find some beat up cans just for the oil!!
