here is the first of a long string of Valvoline SynPower 5w-20 UOAs.. I used a Mobil 1 filter because it was more convenient at the time. And although the lab report talks of extending my change interval to 8K miles, I have no interest in that. I will continue to change it when the maintenance...

I went with Honda's recommended 5w-20, used a Honda filter, and Mobil 1. (It didn't affect my gas mileage from what I could tell. I averaged 35.2 mpg over the last 9K miles, getting about 33/35 around town and 42 on the highway.) The maintenance minder went off at 5,599 miles, so that is when I...

Thanks everyone for the advice. The car is some sort of CPO, but we bought it at a Toyota dealership and it came with their dealer specific warranty. The oil was changed, but from the (little) paperwork I found, it looks like they changed the oil and then used it for around 3-5K. When I picked...

1. What kind of vehicle you have: 2007 Honda Fit Sport with 27K miles, manual transmission, bought used a couple weeks ago. 2. What your owner's manual says -- not just viscosity, but certifications (look for acronyms like API SM, ILSAC GF-4, etc.) and change intervals as well: 5w-20 for all...

yeah those last two were both relatively normal driving, both using Rotella T 5w-40. I haven't really pushed the car as much since I'm getting a little nervous about the mileage. The next UOA will be the first one with Rotella T6, but from what I can gather there really isn't a difference.

here are my two latest UOAs. let me know what you guys think.

I noticed that the UOA said 15w-40, that is not correct, I used the 5w-40. I am running Cobbs off the shelf stage 2 93 octane map, I know these maps almost always run richer but I think that the fuel went up because it was winter and I was letting the car idle every morning for 5-10 minutes. I...

Here are my two latest UOAs. I was still running Rotella T 5W-40 during both. I know that Mobil 1 is not recommended for Subaru WRXs but I had a 5 quart container left over from before that knowledge was imparted to me so I used it. I just passed 3K miles so we'll see in the next couple of weeks...

I took a data log the other day to try and figure out if I actually have knock present.. to make things a little easier here is the thread I made on NASIOC.com in the Cobb Tuning Accessport section of the forum. If anyone that knows Subaru's wants to take a look and give me feedback that would...

Quote: it seems that the oil has sheared down quite a bit I'm going to come right out and sound like a noob, but what do you look at to see if the oil has sheared down?

This is the first time I have ever used anything other than Mobil 1 (70K-108K) and before me the first owner used Valvoline synthetic (it's a guess on the first change but I'd have to say 3750-68K, dealership oil was used from 68K-70K) but that is what I heard from the dealership so there is no...

I understand that he is a professional at what he does, I was under the impression that Dyson was a different lab doing the same work so I would be able to double check the sample for more accurate results.

Yeah I know what you are saying. I might as well keep all of the test conditions as near the same as possible to get a more accurate idea of what is actually going on. I think a road trip is in order... I want to know now!!

I justed checked out the Dyson Analysis site and didn't realize it was just a guys opinion of the results for an extra $99 (I get that from you guys for free!) What are the other labs that do the same work as Blackstone so I can cross compare my results?

Well my concern with using Mobil 1 should be clear since I switched to Rotella T. At 104K miles when I changed the timing belt the air filter looked perfectly clean. Subaru's recommended change interval is 30K miles, which I am right around and plan on doing. The car has been at Cobb's stage 2...
