Why do you say that Motorcraft has a better base oil than Havoline? I'm definitely not someone that can look at the product data sheets and tell this, but it look like to me that Havoline has a better base oil in the 5W-20 grade?

I believe the urban legend here acknowledges that the base oil in Motorcraft and other Conoco oils is 60% Group III. And when the new SM/GF-4 specs came out some oil companies chose to meet them by going with a quality base and others with the add-pack. This may be over-simplified though.

You don't decide that... ...... let your engine decide which one it wants! Do two OCIs with each. Your engine will let you know... ie... engine sound.... dipstick color/cleanliness... oil pressure hot & cold.... oil life.... etc.

We've seen some excellent UOA's for Motorcraft 5W-20 in Ford F-150's, both the 4.6L & 5.4L engines. Trying to pick any 5W-20 using base oil as a criteria is a tough job. I think as a minimum, all the major brands are going to be the equivalent of Grp II+ or better just to meet the volatility requirements of the GF-4 test sequences. And it's a combination of base oil & additives that generates the passing grades. As far as the ConocoPhillips brands being the clear winner due to the Grp III in the blend, keep in mind that this is a blend of 4 cSt base oils with 123 VI for the Grp III and 95 VI for the Grp II portion. And the 4 cST Grp II has a 10 degrees F pour point. Compare this to other major brands which utilize GRP II+ base oils in the 118 VI index range. Again, not knocking the CP lineup of motor oils, it's just that I see some of these "better base oil" statements & I don't see the data to back them up. [Smile]

No data applies to your engine. You have to try different oils to see what's best for your engine. What works in Joe Blow's identical vehicle next door may not work in yours as well. Experiment & get a UOA done between 10-20K.

I've got an 05 F150, 5.4, 10K miles. Dumped the factory oil at 5K (I know..I should have dumped it earlier). Now running Pauls Brew: 4 Motorcraft 5w-20 Blends 1 Redline 5w-20 2 GC's My first UOA at 10K is being analyzed at Blackstone as we speak, stay tuned for some numbers.
