above 20 degrees starts runs flawless
below 20 degrees starts runs 20 seconds shuts down flashs code 30
turn off restarts runs for 20 seconds does this 4-15 times then runs
great all day runnin mobil one 0w40 seems to be getting worse
any ideas where to look

30 is an oil pressure code. Maybe the sensor doesn't like 0w40? Maybe check your oil level also.

oil is full doesn't make sense when it runs great once it gets warm enough
used to clear up after the oil light goes out now still happening 3 or 4 cycles
after the oil is warm
