Word. When I used to be a distributor for AMSOIL, they advertised like 15,000miles on one change. I think BMW advertises the same.

I used Mobil 1 in my GTO but haven't had a chance to change this oil yet. I think the last time I looked I was around 50%.

The only way to really know is to send in a sample.

Hell yeah I would never consider running more then 3k regardless what any test says. $40 every couple months is cheap insurance for piece of mind knowing I have fresh clean oil in my engine. Every engine I have built, treated this way and then torn apart for upgrades or to sell etc always looked cleaner and better then when I put it together. Some consider it throwing away money. I throw away four times that every month for car insurance that I have never once used in the past 10 years...

8qts there's no way to stay under 50...

The thread is on here somewhere (wont be on the shitter long enough to look) but I was going 5k on Motorcraft synthetic blend. I sent it in for analysis and it had a little life left but was time to change. I have RP 5w-30 in now and am going til 7500 when I'll send it in again to get tested.

Will do. If the factory stuff was looking good I have faith a good synthetic will be just fine to 7500. The car will have a little more abuse this go around though... I'll finally have time to finish the nitrous!

Just out of curiosity, do you simply mail off a small vial of used oil?

Gotta pay attention and shop for deals. It can be done.. $32 for the 5qt and filter then usually they have the single qt bottles on sale for 6-7 at the same time. Might go over a tick with tax but you will get close. There have been many times I go into our local oreillys and they have the valvoline vr-1 race oil for $2 a qt!!! I grab It up every time I see it!! Still a good deal for synthetic oil. Damn 8 qt mustangs... Haha

Vr1 is some good shit. Zddp and zinc is through the roof! Really only for a engine thats get pissed on and changed regularly. Like 3k miles tops. Value oils you can get under $50 all day for 8qts and filter. Any given day you can go into walmart, oreillys, autozone and they will have a special on a name brand oil.
