I have a little question, when I start my truck the oil can light is on because there is no oil pressure yet, I umderstand that. So the truck continues to idle and just when I start to gain pressure the trucks idle seems to kick down a bit for a second or so and then it kicks back up to a normal idle. From the looks of it it's like the truck bogs down to gain pressure, but then it kicks back to normal before I have full pressure at idle. When I'm driving, parked and everywhere inbetween the oil pressure is just dandy. Anyone have an explaination for the kick down of my motor when I initially start it?

 

Could be the grid heater but I think it is still too warm for those just yet. Watch the voltmeter and see if is moves when the idle goes down.

 

^x1..Is that all on No.2 and not WMO in your sig?

 

I'd say X3 or whatever. Sounds just like a grid heater cycle to me. As long as you don't see a drop in oil pressure (enough to trip the light) during operation, don't worry about it.

 

Nah, no oil, just straight #2
