That's why you use mechanical guages, I don't even trust that electrical junk in a daily driver, cooked a motor in my tow vehicle once because of a temp sending unit went fubar on me!... |
Yeah, you just have to worry about your oil pressure line springing a leak and pumping hot oil all over the interior.
It depends on the application. If it's a short run and easy to keep an eye on (not behind panels or running under floors and such), I like to have mechanincal's. If the hose has to be run out of site, or on a long run (say up from the engine compartment on a larger boat), I say go electrical.
As far as the oil temp goes, I did a little research and found that all oils have to meet a certain sheer requiremant based on their viscocity at 100*C, with a maximum sheer rating at 150* C. 100*C = 212*F and 150*C = 300*C .
So at 250* on the gauge, you're about 3/4 of the way to the "redline"... probably not the best thing, but not the worst either.
I'm sure one of the engineering types around here will see this and let us all know I'm full of shit, but that is how I understand it.
A dog doesn't care if you're rich or poor, educated or illiterate, clever or dull. Give him your heart and he will give you his.
