2007 yukon when should I CHANGE THE OIL HOW MANY

check oil level low or no oil causes no start so does --your oil sender may have failed --oil sender also has a screen filter which causes low or no pressure =oil pump problem ==the truck wont start or may start and shut off immediately

That could easily be melted grease from the engine compartment or spilled oil when filling your oil during changes or top off.

2008, I would start with replacing the oil pressure sending unit. Or maybe adding oil.

oil pump my be going out take a look at it.

Did you ever get an answer on this?

You should change your oil at least every 3000 to 4000 miles or in your case every 4828 to 6437 kilometers. If you use fully synthetic oil you can do the change every 5000 miles or 8046 kilometers.

Sounds funny, I would take it to an indepened repair shop and have them check it out, we have many customer's with Yukon and have not heard of that, I have a GMC with over 315,000 miles and between oil changes, maybe a qts low, have it check else where.

Probably just the oil sending unit internally defective.Just have them install a pressure tester and make sure the pressure is good.I`m sure this will be the sending unit.Hope this helps.Good luck.

there is a button on the dash, it says ENGLISH/METRIC, push it.

THE OIL PAN IS GOING TO BE THE LARGEST PAN AT THE BOTTOM OF THE ENGINE. THERE WILL BE ONLY ONE PLUG ON IT. TO RESET THE OIL CHANGE REMINDER FOLLOW THESE STEPS. TURN THE KEY TO THE ON POSITION, BUT DO NOT START THE VEHICLE. WHILE THE KEY IS ON PUSH THE ACCELERATOR PEDAL ALL THE WAY TO THE FLOOR THREE TIMES. THIS WILL RESET THE OIL REMINDER.
