Experience with synthetic oil?

about to do my yearly maintenance on my rig. Looking into buying some synthetic oil this year. Anyone have experience with that? any input is appreciated.

It’s all I ever use. RV, generator,cars, motorcycle. I like Rotella

There are many pros and cons. A buddy of mine has the same diesel truck as me and runs conventional oil with no problems. I’ve always switched my vehicles to synthetic after the first two oil changes just for some added insurance. If it does what they say, then it’s worth the extra dollars and peace of mind to me. I also use Rotella and do occasionally alternate the synthetic blend for an oil change here or there. I’ve put 170K and 180K on two different diesel trucks using synthetic oil and never has a single engine wear related issue.
