Synthetic Oil Questions - Changing to Synthetic
Hey guys,
I got my Z 3 months ago and was just due for an oil change. I decided to go for Synthetic and now I have a few questions about it. I also didn't know it was so expensive ended up cost about $43 after buying 5 quarts of mobil1 5w30 and mobil1 oil filter.
Q1. How long do I need to wait before I change my oil again? Some says 5k, some says 7.5k what is the norm? I know it varies between drivers but my driving habits is just normal, taking it easy. I drive 2-3 days at most (weekends) and I don't drive her hard either.
Q2. As for as Synthetic filter goes...do you change it every time you change your oil just like normal motor oil for does it last longer?
Thanks everyone, sorry I'm a newb at this...never used synthetic oil before.

Change the filter wit the oil, if you dont have an extended performance filter like Mobile 1 or Amsoil with the synthetic media then you need to change your filter sooner. As far as the oil change intervals, my persomal opinion is to go 5 or 6000 mile and get it out. Some say its a waste but its my peace of mind and my money. Cheap insurance if you ask me.

If you do 6k oil changes , i recomend swapping the filter at 3k and adding the 1/4 quart of oil you lost with the filter change.

Thanks for the help guys, right now I'm using the Mobile1 filter and with your info I'll change my oil/filter every 6k
Hm...interesting, thanks for the link bro. I'll take some time later to read the 11 pages and determine if I should change next time. I'll also need to find someone around here that sells the Amsoil or Royal Purple or Castrol german synthetic. What's your take on that?

I use 5-30 royal purple full synthetic with a K&N oil filter. I do about 5k on both the filter and the oil. The filter holds up fine for 5k, but it is the most expensive one you can get. I've stabbed a screw driver into them to check out the insides. Good filter with out a doubt, 5k miles should work.

I would recommend going to AutoZone or Advance Auto Parts and pick up Penzoil Platnum. It is better than Mobil 1 now. Since M1 change their formulation it hasn't been that good. PP has proved to make the engine quieter, last longer, etc. It's also cheaper. You can get it for $3 a quart right now on sale.

The best oils are Amsoil, Redline, Mobil 1, Penzoil Platnum.
Stay away from Royal Purple. It has shown to not be very good in tests.

GC castrol has been discontinued. I checked with Autozone a week ago, and they are not receiving anymore. I recently switched to Castrol syntec 5w30 with K&N filter. I will have oil analysis done after 5,000 miles. I have always used Castrol GTX with great results and expect no less from their synthetic. I can tell you that my engine idles and drives significantly more smoother now.

I have been on that forum for 5 years. I can tell you that PP is the best store bought oil currently. I use Amsoil myself though.

I know Napa sells Amsoil as well. You might want to check into that.

Mobil1 still makes PAO based oils. The 0W-40 and 0W-30 are both a PAO base stock oil, at least there's no way their NOACK and HTHS levels are from a Group 3 oil. The rest of the line-up has definately gone to a G3, except for maybe the 15W-50, there's copmpelling data to say it's also a PAO still. In any case M1 SuperSyn is just no where as awesome as the old TriSyn formulation.
GC seems to have gone the way of the dinosaur, and for the poster who said to use some Castrol Green, if you can actually find it then buy it all and sell it for a massive profit. The old green GC is top notch.
Amsoil is all PAO, and the 0W-30 has performed stellar in the VQ and would be an excellent oil for an extended drain interval.

The sticky has an average result from three UOA's done on three diferent VQ's, and it's been great. I don't think the PP was ever a PAO based oil. Maybe the older Pennzoil Synthetic, but the PP is only a few years old, and has always been a G3+. PP has VERY low TBN numbers from the VQ and I would not in any way think of going an extended drain interval with it.
