Re: WHY OIL GOES BAD….AND HOW YOU CAN PREVENT IT
Greg,
Thanks for your kind words.
I can tell that your background is more extensive than the average guy out there as far as lubrication is concerned.
Once again, you are right, or at least right in the sense that you can speak of what you know and understand. Evidently you are not familiar with some of the "other" technology that is out there.
SWEPCO is one of a few smaller manufacturers who have produced gear oil which is compatible with yellow metals as well as having the capability of protecting the hypoid gears in differentials. It is in the type of extreme pressure additives used that makes the difference. Yes, they are more expensive than others, they not only work, they outperform the standard GL-5 oils on the market. Usually, given the same application in gear boxes, you can usually see a definite difference in operating temperatures, with 25% or more not being unrealistic. AND they are more compatible with seal materials than others are, especially the popular synthetics on the market. I have landed more Sprint car teams with the 210-80/140 who used to use Redline Shockproof gear oil than I can count, with the following results:
1) No more puddles of gear oil under the car in the race trailer.
2) An average of 25 degree F reduction in gear oil temperature (taken with a heat gun)
3) Longer equipment life.....many teams with excess of 5 seasons on the same ring & pinion gears!
Whether it is automotive, trucking, construction, industrial plants and even racing, they have a product which excels, it's just a matter of matching up what is best suited for the application.
I'm not sure how to post a pdf file onto Jeff's system yet, but if you would like to respond personally and give me your email address, I'd be glad to send you a Viscosity Equivalents Chart which you might find interesting.
