using different name brands question ?

[aztec12]

sorry for the question but i posted this before and didnt get answers,so here goes again....I been changing the oil in my f150 with mostly 5w30 and a few 10w30(oil changes)the thing is that everytime i change the oil i use a different brand of oil say Pennzoil this time,next castrol,next valvoline etc.I cannot stay loyal to one brand name of oil mainly becouse of this site BITOG, i hear a good thing about a certain oil and i want to try it,the i hear a different oil and im also switching again.so my question is im i sludging my engine becouse of the different type of oils im using(add packs)Im good about changing it at every 3k,and by the way im talking about regular conventional oil and blended oil. tks

No.

P.S. - Use 4,000 mile OCI's...

No, your routine is not going to cause sludging.

With 3,000 mile OCIs almost any modern oil of the correct viscosity is going to do just fine by your truck.

It's preferable to not mix oils at the same time, but as for using a different brand at each oil change...
"Second, you can change the brand oil used any time, just continue to use the same high quality level recommended by the engine manufacturer."
