My question is, would the Dodge be better served by using Mobil 1, or the extended protection flavor? Pennzoil Platinum is certainly worth consideration, but the Ultra isn't available locally. It is my intent to use either a Mobil 1 or Fram Ultra oil filter. Another thing to consider is the fact I drive a whopping 4.5 miles to work, 1 way. The truck does do a lot of short tripping (1-3 miles). Maybe a 10,000 mile oci isn't a good idea under these driving conditions? One last thought. I HATE spending money on new, over priced trucks! This little guy should hopefully run at least 4 more years. I solicit your thoughts and comments.
Reread your post there are several reasons not do extended OCIs.
By the way what does the OEM manual recommend for your short tripped driving conditions.
Ar_tc hit the nail on the head when saying your truck has a small sump. The key factor often neglected on this site when it comes to extending OCIs.
In OZ every instance where Holden Toyota Ford etc extended the OCI the sump capacity was also increased proportionally, have not ever read where an OEM extended the OCI by switching to full syn oils whilst maintaining the original sump size.
As far as crawling under a truck to change oil perhaps you are spending too time much ????? and have gone soft. Time to toughen up dear friend.
Criteria for low risk decision making
1. OEM manual check extreme conditions apply
2. BITOG should be confirming OEM guide not contradicting if not check credibility of advice rendered
3. Use an approved / certified OEM engine oil if available
4. If routine todate has worked and vehicle is in condition why fix what is not broke
5. Oil changes are cheap new trucks or engine rebuilds are expensive
