Re: Switching to mobil 1 synthetic tomorrow-10w30 or 5w30?
I only have 5100 miles
I changed it after the first 100 miles and
used Mobil 1 5w30
I see alot of comment here in the post about it being
real thin - and they are right - It is real thin.
At 6k I will change it again using Mobil 1 10w30
I also use a GM PF 59 filter longer than the PF53.
I have used Mobil 1 10w30 in my 91 since new - under the valve cover is like new and my oil pressure went up in both trucks after the switch.

I was under the impression that it wasn't a good idea to switch to synthetic until after the complete break-in period.

I read that it is bad to switch to synthectic after a long period of time. here is a good link.click on The Engine Oil Bible on the left.

Not saying you shouldn't run it at all, just saying that you should probably let the engine properly break in with dino oil first. I've running Mobile 1 10w 30 since around 25k and everything is going smooth.
