switching to synthetic oil

Quick question... I'd like to switch to synthetic oil in my 2001 Chevy Z-71 at my next oil change. Any special steps I need to take when switching? Do I need to purge out the old oil, or is it a standard oil change and just add the synthetic? I run 100% synthetic in my Harley, but I've always had it serviced at the dealer, so I don't know what they did when they switched. Also. the 2006 GTO's come with synthetic (mobile 1) correct? Thanks in advance.

Yes, our GTOs come with synthetic. I don't think that there are any special steps to switch to synthetic oil though. I figure that all you would really have to do is make sure that the old oil is drained out as much as possible. That's all I did when I switched in my other car. Nothing bad has happened since, so I figure that it'll be fine to just do it that way. Hope I helped.

I would get an extra quart of synthetic and once the old oil is done draining use the extra quart of synthetic to help push the rest of the old oil out.

Good idea. Are you talking about just pouring the extra quart thru the motor and into the drain pan?

Hummm, 2001 Chevy. How many miles? Synthetic cleans an engine differently from Dino. If your car has over 30,000 miles on it, you might consider a blend rather than a straight synthetic. Otherwise, that CHevy might start using oil like it never did.

It's got a little over 67K on it. If it starts using oil, I could switch back to dino, right?

I have also heard of seals leaking with synthetic after using dino oil for awhile.

I think it's easier to switch in the other direction; synthetic:dino, although I don't know why anyone would want to.

Ah, no it does not work that way. As a part of combustion, byproducts collect and seal many parts of the combustion chamber. Synthetic has stronger cleaners and will remove those deposits. This COULD cause your vehicle to use oil. Then again, it may not. There is no way of telling before. How has your fortune been lately?? To get some of the benefits of synthetic, I would recommend a blend rather than 100% synthetic. Best to ya, it is a gamble with cars over 30,000.
