I have done some research about oil distributors in my area. It turns out all of the following oils can be had for the same price, ~$5/qt. Some require a 6 gallon case purchase others require just a 6qt case purchase. It doesn't really matter to me as it will be used whether in my Neon or in my fiances Grand Cherokee.
Chevron Delo 5w40 - $5.06/qt when purchasing 6 gallons
Pennzoil Platnum Euro 5w40 - $5.16/qt when purchasing 6 qts
Mobil Delvac 1 - $5.04/qt when purchasing 6 gallons
Quaker State 5w40 - $5.16/qt when purchasing 6 qts.
Mobil 1 Turbo Diesel Truck - $5.64/qt when purchasing 6 qts
Then there is the Rotella 5w40 that is available at Walmart for ~$17/gallon, $4.25/qt.
Of these options I don't see the M1 TDT as being an option just because Delvac is cheaper and either the same or better than the TDT. All of these oils meet at least SL spec which is what my applications require.
The cost is similar enough for all of these that the price difference is null.
I have been thinking I would get the PP 5w40 for my Neon to try first as I have been happy with the PP 5w30, but I wanted to try a thicker oil to quiet the engine down some and offer good protection. I am planning on a UOA after my 5000 mile run of PP 5w30 and the a UOA on a 5000 mile run on the 5w40 that I pick.
The Jeep Grand Cherokee currently has Rotella 5w40 in it and it seems to like it. I wanted to get a UOA on it regardless of what kind of oil was used as the vehicle was purchased just a few thousand miles ago.
In the end I will probably use the same oil in both vehicles.
So I guess the main question is...
Which of these oils would you use?
