Should I idle up while parked for better oil pressure?

^^ so when we idle, we should rock it back and forth every lil while to actuate the cylinders? Not sarcasm.... just questioning. All seriousness.

 

Look at it this way. If you absolutely have to run the engine (which is almost always a must up here due to -35 or colder in winter), would you rather burn a little more fuel or take out an engine? First company I worked for a driver parked his truck and left it idling. Truck ended up sitting and idling in the corner of the yard for a week and a half. It slobbered so much fuel past the rings I estimated it dilluted the oil 1.5:1 (because I got 3.5 drain pans full of "oil" out of the pan instead of the usual 1 pan full). Cost the company a perfectly good C12. It was so far gone that even with fresh oil it wouldn't get above 10 psi. Drove it down the road to the dealer and let them deal with.

 

I drove a Coronado with rebuilt Detroit 60. I was told by another driver and the head mechanic to idle up so as not to "wash" the Pistons. We didn't have apu or def engines. Not sure if they were both full of shi# or what but I idled up. Dang I miss that truck.

 

I idle every time if I keep the engine running. Always have. Like have many said here already, loading injectors, washing cylinders, oil pressure. I bump mine up until I get 60 psi of oil pressure, usually around 900 rpms or so.

 

The new volvo motors are supposed to idled up when parked. If you bump them up they kick into a clean idle mode also smooth out a little. They never kick into it if just left at a low idle.

 

I would idle mine at 800-900 rpm minimum and if it was really cold I'd go to 1000 rpm to help keep the engine warmer.

 

I run an old mechanical engine and have always idled up to at least 900 rpm if letting it idle for any length of time at all, summer or winter.

 

I would recommend raising the idle rpms up to around 900 as well. If for nothing else, keeps the exhaust temps up and the exhaust pressures up and allows the dpf to cook out the soot as it comes in. Still it will go into parked regen mode on its own but that should tell you limit idle time every chance you get.
