I have a 5.9l engine and I'm just curious to see how many gallons an hour you are burning in park with a cold engine, oh and with regular gas. Mine burns about .8 g/h and less than .7 when it's warmed up. Please state in your response what engine you are running and please turn off your a/c (or state what you did) sorry I'm asking for alot but every little thing makes a difference. Thanks!

 

When mine worked mine was like .85gph warm no ac
