Mobil 1/Penzoil platinum (what ever is on sale) and Fram extended guard filters since new...I change everything out at 5,000 miles...No knocks, pings, dings, valve noise, dry starts or any other nonsense.

i'm using mobil 1 5w30 esp with a mopar filter...
only 11k on my '08 rubi auto...no worries...[no dust]...
changing interval = 5000

My That is what I do. Every 3k is overkill and 5K maybe also. The only way to actually know when the oil is broken down enough to change is to have it analyzed. I'm not going through the trouble, time, or expense to do that. I feel comfortable a 5K intervals and it is easy to remember. For me that is only once or twice a year, usually anyway.

This may be off your topic but, I did notice during my trip to wally world that the only recommended Fram oil filter was the extended guard. The other post in this thread talking about the drain valve makes perfect sense now. I too had the impression Frams were the low-end cheapo filters. I felt better about buying the EG in the past due to the reports on this forum.

I've ran the M1 EP 5w20 and the M1 EP filter. All has been well and good until it got cold outside. I have since noticed that when its cold, I do get a dry start...I made the switch to a Fram filter (as per recommended on this forum) and I STILL get the dry start tick. Going to switch back to a Mopar filter to see if this is the problem. If not, I may end up switching to 5w30 to see if this helps. I've never really liked the fact that this motor uses 5w20 oil anyway...only reason I have ran it this long is to not void anything with the warranty.

BTW, when I removed the M1 EP filter, there was indeed oil still retained inside the filter...so its not like the filter is dry by any means...but for some reason when its cold, my jeep has a dry start.

I live in VT...very cold winters, regularly below zero temps when I start up in the winter.

I've never had a problem, but have always used the Mopar filter and 5w20 Mobil 1.

Oh hell why not jump in? I've been running Mobil 1 5W-20 with a Fram Tough Guard 3614 filter on a 5,000 mile change interval since the first oil change at 1,151 miles. Only dry starts I ever had before switching to the Tough Guard was with the assembly line installed OEM Mopar... Whoot! My B&M #70268 SuperCooler was delivered during this post! ...Knock wood in 19,500+ miles I haven't burned enough oil between changes to register any loss on the dip stick.

Mobile 1 EP is NOT a full synthetic, regardless of what is on the can. is it good oil? Yes! Can you go 6,000 miles? Sure! You can go 6000 miles on factory Dino oil. I would run Amsoil or Royal purple 0w20 or 0w30. I would get a good filter like WiX or Amsoil, and run a WIX air filter as well. Don't run a "high-flow" air filter that let's too much dirt in. With a real synthetic (and good air filter) you could go 10,000 + miles on an oil change while just changing the filter at regular interval. Don't believe me? Go for yourself and do an oil lab at 6000 miles and see if the oil is still good. I have had Amsoil, redline, and royal purple last 15,000 before testing showed loss of viscosity and shear protection.

Going from 5w20 to 5w30 will NOT help start up viscosity. If you want more protection on startup, run a 0w30 or 0w20 synthetic oil. Want more info? Google "bob is the oil guy" and read about oil and tests.
