That's an old wive's tale, there are no issues with synthetic in our motors. I've run it with more miles than that and had no problems, you can even go back to dino if you wish.
Perfectly fine to do. The only thing I wouldn't do is flip flop each oil change between syn and dino
I have gone back and forth from PAO based, hyrdocracked synthetics, blends and conventional all the time...not an issue yet on any vehicle I have ever owned.
Alright is there a best brand for the truck or doesnt it really matter?
"Best" is a tough word to define, really there are a lot of good options rotella T6, Mobil 1 TDT, Delvac 1, Amsoil, Schaeffers etc etc.
Really your wallet will care about what oil you use more than your engine IMHO. Based on my budget and operating conditions I run Rotella t5 10w-30. Seems to be doing just fine, just give how your operate your truck some thought and see what oil fits your operating conditions and budget. Really there are a lot of good synthetics so long as it is a C rated oil you can't go wrong.
