hey sorry it took me a bit to get back on this.
I've been busy (understatement of the year)
mine is a 2000 and i changed theil to full syn 10-30 toaday and sure as hell the low oil pressure light is on...
kinda thinking i ahould change the sending switch. sorta wondering if i should drive it to town to take the kid to work or take the truck?
I assume it is fine and it is just the lower viscosity syn flow rate but it does make ,e nervous driving something that is telling me it is about to explode lol.
update...i did just drive it and light went outand it seems fine
i suspect i will swap out the pressure switch buy a good 15-40 now that i am out of the 10-30 i had already and stop worrying about it lol
i need to tear into the truck and do some mods before the snow flies
and i need to cut split and haul another 6 cords or so of wood before that happens too...
in other words i have got more left to do than i am likely to get done...
