Default Awesome Amsoil 5W-30 UOA

So I just got my UOA back from Blackstone. Didn't really know what to expect because the car is a 99% stock 2005 WRX (STI catback) with 88,000 miles and I'm the third owner (no idea how the previous owners treated it). Ran Amsoil 5W-30 for about 4,000 miles. Results posted below.

You're obviously mistaken. EVERYBODY who's ANYBODY here on NABISCO knows that the use of a 5W30 of any kind will result in the immediate explosion of a Subaru turbo motor.

Yeah same here been running amsoil for about 15k or so now. How much and how long does it take to get your results back from blackstone? Ive been doing 4k change intervals with the amsoil and after this change will be pushing 4500 I would really like to see how the oil has been holding up.

Great uoa, but it is only 4k miles with 1 qt added. How many miles into the OCI did you add the make-up oil? That probably helped the visocisty number.

Those wear numbers are great so the previous owners probably did not use Mobil1 5W-30. I use Amsoil, but I wouldn't use it with 4k intervals. My OCI's are 8k.

I usually get my UOA results back from Blackstone Labs (PDF file e-mailed to me) in less than one week from mailing my sample via the USPS. The standard UOA costs $22.50, I sometimes opt for the optional TBN test to see how the oil is holding-up over the life of my OCI. They charge $10 extra for the TBN.

re bluesubie: I added the oil after doing about 1500 miles, so the entire sample was in there for about 2500 miles without having any more added to it.

Having run Amsoil 5-30 for 10k miles with an Amsoil (ea012) filter change midway id say it holds up as good as anything else you could possible put in there. 1 qt makeup on top of filter change makeup.


I had to change it at 10k due to a leaking stock turbo inlet (unknown at the time) letting in dust and raising the silicate count out of control. Otherwise it was ready for more. Its just unmatched for longevity.

All based off Blackstone sampling.

A few buddies of mine kept swearing by this stuff, so I gave it a shot and have been running the Amsoil Series 3000 5w-30 in my car for 2 years now.
http://www.amsoil.com/storefront/hdd.aspx

I was a bit skeptical at first with it being the Heavy Duty Diesel formulation, but after some research, I decided what the heck. It supposedly holds up really well to the higher temperatures making it a solid choice for turbo vehicles. I also just noticed that it's a bit more expensive then the ASL.

Anyway, thanks to the op for posting this up. I'm going to have to send mine in for testing one of these days to see how well it's been holding up.

I added more comments at bitog and linked a run on ASL in a 2.5T at 7k+ miles (hello RonJitsu). I have a bit of xW-30-phobia unless it has some esters (SSO, RedLine, GC, etc.) or maybe exotic base stocks like vege oil .

It's expensive because it's loaded with the old API CI-4+/SL levels of additives (i.e. lots and lots o' zinc and phosphorus ). It has more than the CJ/SM DEO 5W-40.
