Oil & Fuel cold start-up oil pressure

[digger2]

Hey guys,
Bought myself a new B26 TLB back in October,works great.Have about 14 hrs. on it so far.When i bought it the weather temp was on avg. about
50-55 degrees.The oil press. light on start-up went out almost instantly
in those temps.But now since the temp in the last two weeks has dropped down to about 20 or a little less it takes about 3 seconds after cold start-up
for the light to go out.
The reason i'm concerned is because i did have, until i traded up to the
B26,a B7610 that i owned for 3 yrs. that i could start when it was 0 degrees
out and the press. light went off right away.
My question is,how long does your light take to go out when starting under the same conditions?Cold start(20 deg.),unheated building,no block heater,sits maybe a week or so. I was thinking it could be a more sensitive sending unit than my other
tractor had.Or maybe the dealer for one reason or another has some sort of "summer" weight oil in it.This tractor did actually arrive at their dealership in July.I'm sure they did'nt change it since they put it on their lot back then.
Probably nothing but what do you think???? digger2

If it were me, I'd change the oil and filter using a good multi-grade oil for diesel applications just to be sure. If the dealer did install 30wt oil, at 20 deg the oil would definately be too thick to properly lubricate the engine until after the engine warms some.

By the way, Rotella has a 5w40 synthetic oil, if you're interested.

Better safe than sorry!
