Serious question, what difference would synthetic make at break in if it's all the same viscosity?? I don't get it.

I have been running MobilOne since I bought, with 22K on it. It was clean when I got it and it has never used oil since, and we have 31K on it now. I change at 5K, which is when my idiot light comes on, but I usually get it right before then.

I agree, you should wait at least 3K before converting to synthetic on a new vehicle. I used to wait until 7500 miles before making the switch with my new cars and trucks.

Just my 2 cents worth.....

 

I guess I got lucky. Not only did I get free oil changes for life through Chrysler when I bought my Jeep I also got free oil changes for life through the dealership. So I get my oil changed every 1500 miles! no not really. Anyone else get a similar deal?

 

Porsche does. They have been doing it for several years.

 

props to the man.... your a gentleman and a scholar Rocky

 

My 2007 has it. Went off on a trail run and every-time I went from park to drive it kept signaling on dash and with chimes.

 

I switched mine first at 3000. I went straight to Mobil 1 and change every 5000. To the OP, I bet they didn't reset the light when you changed the oil. On the synthetic issue, I got a 2011 GMC 3/4 ton with a 6.0 gas engine recently. GM is running synthetic in all the gas motors now. There is no scheduled maintenance. The owners manual says to change the oil when the "change oil" light comes on. That was a new one on me.

 

the properties of each oil are different, synthetics have shorter molecular chains than a conventional oil...hince there is more "cushion" in conventional oil....this is why it is suggested for the break in period...

 

In 1993 I bought a new Chevy 1500 truck; the salesman said I did not have to wax it because it had a clearcoat paint that didn't need to be waxed . I ignored that "advice" same as I would ignore the new owners manual telling me not to change the oil. I'm sure the light will come on before any immediate damage is done, but is that best for long term ownership? As a result of extended drain intervals, will the motors see as many miles before they need repair in subsequent years, after the warranty is long gone? GM has nothing to lose there, motor is fine during warranty, but potential reapirs, at consumer expense, come a little sooner after the miles accumulate.
