Question about 2008 GMC Sierra 3500HD 2WD
Should be driven for 30 miles all highway miles to reset the exhaust filter. do you let your truck idle a lot. because the new trucks you can cut them on and off just like you would a gas truck. idle will make filter build up faster and running around town alot of stop and go . Don't be scared to blow it out that is really all you are doing is blowing it out. Your owner manual should have alot more details in it about cleaning your filter out. If i can help just re post.
Thanks dodge tec
