Are you saying the kero is in the oil or the fuel?

I've been out of the lab for the past 5 days. We are running these oils today and I'll send the results to Vetteman this afternoon.

If you like the particle counts Pablo wait until we start running LaserNet fines, It'll blow you away!

We'll that depends on who you ask. These additives form hard wax-like coatings that act as lubricants and exclude air. They do however take time to form so some coolants contain other additives like nitrite that protect immediately. I've seen many diesel engine parts with high hours that look...

This one had a lot of stuff that is not supposed to be in new oil so we did the filtration twice to verify the results. We did not have an unopened container of oil to work with so it is possible the sample or bottle was contaminated after it was opened. Also (although rare) it is possible to...

I too question the value of using oil analysis to judge oil quality, and I certainly would not try to make any conclusions from just a few samples. There are just too many variables that affect the results. The oil analysis test are designed to measure wear, contamination, and oil condition...

Steve you would do well with one of the synthetic 5W40 oils. You application would justify the high cost, but don't expect to run a lot more miles.

Hey that's pretty cool Ross, thanks.

We might be able to do something like that Bul. I'll look into it.

Ross - you are correct. I hope Scot isn't saying bad things about me.

Hi Bul You can order the TBN test kit from Dexsil and do the test yourself. Downside is you have to buy 20 at a time and they have a fixed shelf-life. Mark

Thanks Mola G-man, We need to know the approximate range so I can get the correct standards to calibrate the instrument. We normally use 3 standards to establish a calibration curve. For example we will use a blank, a low standard that is slightly below the expected value, and then a high...

After several requests we are going to start running Antimony as part of our standard analysis. Can someone tell me the expected value? I need to order the standards. MolaKule mentions 25 ppm back in 2003, is this what's being used today? Stinky

From the lab's point of view there are a couple of other reasons to send in a sample of new oil. If the lab runs FTIR analysis they need a reference oil. For this test the instrument scans and stores the reference oil then when you send us a sample it is scanned and compared to the new oil. The...

Some of the sodium additives are soap-like compounds.

220 ppm sodium is not an unreasonable number to be seen in a new oil. As someone mentioned it does make it a little harder to spot a coolant leak. I can't speak for the new coolants as there are a lot we haven't tested, but most of the OLD coolants don't have potassium. The extended life...

These results are similar to what we got on the 5W30 Extended Performance.

Here's what I found. Sample taken 12-15-2004 in RI.

I don't have any Shaeffers but if someone wants to send me some I'll run it. Stinky
