Redline UOA questions.... help!

[DynaSpeed]

This is the debacle - In an old thread, a colleague with the same vehicle and I decided to try different weights (5w-20 & 5w-30) and get UOA's of them. I purchased a case of Redline 5-30 for my 02 Honda Si. It's almost 6k deep and I would like to get a good sample... the problem - I had to dump in about a quart (maybe a little more) to keep it topped off through the mileage. Also, it was recently that I added some, too. The trade-off here is, do I get the UOA and get mixed results? or wait until the next time around to get more "real" results? The finances in getting the UOA's play a factor, also. I don't exactly budget in $60 every few months for UOA's

Assuming that this is the first fill with it, I think I might do it on the next change. UOA's of Redline seem to indicate a lot of cleaning with the first use, so a better indicator may be the second go around with this oil.

Dyna, the lab or analyst should be able to take that into account and still give you a good interpretation. www.bobistheoilguy.com/terry.html

Bob ,get it tested !, like Terry said they take that into account, plus its only normal to add fluid like that. I am very close to testing my 5w-20 Redline, probably sending it in next Friday, so I will have the results a week later. Ive added 1/2 quart in 2500 miles so far. This will be a 3000-4000 mile sample by next week. I will be adding some Redline 5w-30 just before the track event on the 23rd. I am going to drain about 2 quarts of the 5w-20 during the sampling and add about 2 quarts of Redline 5w-30 to hold me over the Gingerman track event to give me a little extra protection. I know Redline can be run for over 9000 miles, but I want to sample before the track event to get a consistent daily driving reading. Sampling after track events can usually show higher than normal wear numbers. When I get the test results I will just have to take into account that it is a 3000-4000 mile sample of 5w-20 and extrapolate from there on the 5w-20 sample.

ahhh fine... I'll take a sample. I was really trying to buy a case of beer instead of sampling some oil, though.
