Exclamation Normal oil to Synthetic

Was wondering if is a problem to switch from normal oil to 4x4 synthetic, I do know that once the change is done, need to stick with it, will this help engine last longer and gas mileage

It's not true that once you run synthetic oil you can't go back to conventional oil.

Kind of depends, how long do you plan to keep it, how hard do you drive it now, how hard and how far has it been pushed before, etc.. There isn't one straight simple answer for everyone.

Is it just me? or is there some kind of odd disconnect between the title of this thread and the content?

Is your engine knocking after you switched?

I was running standard dinosaur juice in my rig right after I bought it (it had 135,000 mile on it then). I had a lifter tap that just drove me nuts!!! I changed to Mobile 1 Synthetic and that annoying little tap has disappeared. Been thru 3 oil changes with the Mobile 1 now...all at about 5500 mile interval +/- 2-300 miles. Still the tap hasn't been heard again.

There...that should tie the threads together...
