If I'm not mistaken starting in 08 the oil filter threads changed size from previous 02-07 filters. Maybe they screwed on the wrong filter and some oil leaked out. Regardless, reason number 672 not to ever trust drive thru jiffy lube places.

 

^^^^^^^^^^^^^^^^^^^
What he said. Never, but NEVER even let Jiffy Lube clean the windshield. 1/2 a quart wouldn't cause a serious low-pressure situation. Good chance they didn't use the proper oil (or didn't change it at all).

 

Upadte after further research, In 08 Chrysler switched from a 3/4" SAE thread filter to a M22 X1.5 thread filter.* Not sure if that is the problem or not but good info just the same.

 

definitely nice to know! thanks Scott!

 

First mistake: took your truck to Jiffy Lube.

 

Big time.

There really should be a PSA on those drive through oil change places..

:gr_patrio

 

My 05 Ram quad cab Daytona (36,000 Miles) was giving me a low oil pressure code and I found out my battery was going out. changed battery, cleared it and never had a problem again, that was 1500 miles ago.:rck:

 

This is exactly the reason I change my own oil.

 

Hear, hear! Faster, cheaper and you know who did it.

 

You got some good advice but I will tell you whats actually wrong. Half a quart low will not cause a drop in oil pressure. The previous filter that was used until 06 will not scew onto your oil filter adapter so that isn't possible. Wrong oil will set a different code "incorrect engine oil type." Your problem can be solved with a flash update to your pcm. Most dealerships will flash it for around $100. Hope this helps.

 

With my new Fumoto valve, I can change my oil and filter in about 10 minutes now.

 

If I'm not mistakin there was a PCM flash to update/correct overly sensitive oil pressure codes on some string of hemis. Think it was even a TSB.
