I just had the oil changed and the shop said they used 5w20 semi synthetic. It is the first the semi was put in it. Basically after 2 days of driving under 100 kms the check engine light came on. i checked the codes and I got the p1521 which from what I see it is improper oil. Should I go back to regular, ignore it or any other suggestion.

Sorry I have an 06 with the 5.7l Hemi

Are you POSITIVE that they used 5W20 ? It will not make any difference if the oil is regular, semi-synthetic or full synthetic. Most members here use full synthetic oil. I have used full synthetic in my '06 HEMI for years with no problem. But the HEMI HAS to have 5W20 weight oil no matter what type oil it is.

NOTE: The StarSCAN® diagnostic scan tool fully supports Internet connectivity.
However, to take advantage of this feature you must first configure the
StarSCAN® for your dealership's network. Make sure the StarSCAN® is
configured to the dealership's network before proceeding. For instruction on
setting up your StarSCAN® for the dealer's network refer to either:
"DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online
Documentation", or refer to the StarSCAN® Quick Start Networking Guide.
The StarSCAN® Quick Start Networking Guide is also available on the
www.dcctools.com website under the "Download Center".
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
1. Install a battery charger and verify that the charging rate provides approximately 13.5
volts. Set the battery charger to continuous charge. Do not allow the charger to time
out during the flash process. Remove the charger from the battery when the flash
process is complete.
2. Connect the CH9410 StarSCAN® ethernet cable to the StarSCAN® and the dealer's
network drop.
3. Connect the CH9404 StarSCAN® vehicle cable to the StarSCAN® and the vehicle.
4. Power ON the StarSCAN®.
5. Retrieve the old PCM part number. Using the StarSCAN® at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the PCM in the list of modules.
c. Select "More Options"
d. Select "ECU Flash"
e. Record the part number at the top of the "Flash PCM" screen for later reference.
f. Select "Browse for New File". Follow the on screen instructions.
g. Select "Download to Scantool".
h. Select "Close" after the download is complete, then select "Back".
i. Highlight the listed calibration.
j. Select "Update Controller". Follow on screen instructions.
k. When the PCM update is complete, select "OK".
l. Verify the part number at the top of the "Flash PCM" screen has updated to the new
part number.
NOTE: Due to the PCM programming procedure, a DTC may be set in other modules
(TCM, BCM, MIC, SKREEM, etc.) within the vehicle, if so equipped. Some
DTC's may cause the MIL to illuminate. From the "Home" screen select
"System View". Then select "All DTCs". Press "Clear All Stored DTCs" if
there are any DTCs shown on the list.
NOTE: The following step is required by law when reprogramming a PCM and/or
TCM.
6. Type the necessary information on the "Authorized Modification Label" p/n
04275086AB and attach near the VECI label (Fig. 1).

Thanks....i called them this morning and said they did put 5w20 in. They asked me to bring it in so they could hook it up to the computer to look at it. Is this something that can wait acouple of days ans a few hundred km's. i am going outa town and dont have time to get it in before i go.

I know they also said they could not reset the service light as well. I will have to look that up to see if it is something i can do myself.

Where did you get the oil changed ? Just because they said they used 5W20 doesn't mean they did use it. Most members here change their own oil so that they know it is done right. When I don't change it myself I buy the oil and filter and take it to a service center and watch them do the change.

I don't know, but if you don't have time then it will have to wait.

The service interval is reset in the EVIC.

Because of the aftermarket warranty I have to take it to a shop and get a receipt for the oil change. I have tried to take my own but I haven't found a place to do it yet.

I friend of my knows the mechanic and says he is an honorable guy so I will see when I take it in.
