I respect your opinion, Z, & what Yuccaman's article is saying, &--unlike the home-grown terrorists known as the Politically Correct, who shut down debate by labeling all opposing opinions "bigotry"--in the proper forum I'd debate this matter with you til the cows come home. But this is not the proper forum & I need an answer to my questions about oil.
I would like to recommend a book to you both; strange book for a church lady (which I in fact am) to suggest, the author being a fire-eating atheist. It's "Atlas Shrugged" by Ayn Rand: an unforgettable page-turner whether or not you agree with her philosophy. The story of what happened to her "20th Century Motors" company should be the text for high school/college Economics classes everywhere.
My oil pressure gauge has calmed down to the point of comatosity. Just sits there slightly to right of center whenever the engine is turned on, doesn't move no matter what. I'll have my mechanic look behind the dash as Rich suggests, & "loom" the wires of the new sender as Tom suggests.
Now someone please tell me (1) what you think of my plan to run a cheaper & more available synthetic (one I can get in 5 gal. size at Walmart
) for 3000 miles before sending off for Amsoil (You obviously haven't noted, Z, my oft-expressed preference for dealing w/Amsoil rather than a monolith like Mobil 1), and (2) what weight oil will do best for the Maine summer.
(Absolutely Irresistible PS
Z, you say,...."business [sic] are only interested in making money...". But I'm still trying to figure out how it either helps small retailers (including the mechanic you're apparently doing out of his profit) or hurts Walmart when you buy your stuff wholesale. Seems to me that all you're really interested in is saving money.
