96 Passport converting to Mobil 1

[NJFrank]

It's probably been asked before, but here goes anyway.

96 Passport with 118K on it. 3.2 V6 Auto. With the tapping on startup until warmed up and oil circulated. I've read pros and cons on going to Synthetic to eliminate/minimize the valve tapping.

The truck to this point has used Mobile dino oil 10/30 for the most part, changed every 3K and filter. Also uses about 1/2 to 1 Qt oil every 3k.

So is going synthetic going to help, or just spring some leaks.

Thanks for the opinions.

there is a s/b that says change the oil and filter and use mobil synthetic 0w-30. run the engine at 2500 rpm for a half hour and if the noise goes away then your done. aparently there is a build up of varnish that gets in the lifters and the 0w-30 helps to remove it. you could try it but i wouldn't leave the 0w-30 in i would drain it and maybe put in 5w-30.
