This was my 10,000 mile oil change information. A well known 10-40W. I am running an elephant hose and epsolinated + an oild piper panel drop in filter.

Do these numbers sound good, bad or ugly?

I appreciate all of your inputs

How many miles on the vehicle?

Fantastic indeed! A TBN over 12.7 after 10,000 miles and <1% soot is remarkable! Looks like Amsoil's 10W-40 synthetic.

diesel freak,

This is an extremely good analysis with the Amsoil 10w-40 (I recognize the additive chemistry and of course I sold you the stuff ). It normally takes 10k-15k miles for the wear pattern to settle down in these engines, so you can actually expect these numbers to go down a bit more. I would not expect the iron levels to drop however, since they are already very low.

Geoff is correct, you could easily run this same oil for another 10k miles with just a filter change. There is very little oxidation/nitration and the TBN has hardly dropped at all ....

12500 something currently-

look fantastic

if you drained the oil you drained perfrectly good oil out - you could probably go 20k without thinkin about it. Change the filter at 10k and keep driving

(wrong forum BTW)

One question though.. why and what is the
" OXD 10% " what is that all about?

thanks for your replys

DF

OXD is for the chemical oxidation of the basestock due to exposure to high temperature, chemical contamination and conversion, high mechanical shear and is indicative of the total oxidative degradation of the oil.

Yours is excellent, showing you have plenty of reserve and that your engine is running cool and not cooking the oil into coke, crud. sludge, gunk, etc.

Your NOX is also super excellent, showing that the basestock has not been nitrated hardly at all and has a long way to go before it deteroiates.

It doesn't get any better that your results, they are excellent.

Amsoil 10W-40 is dynomite!

Hey SP, thanks alot for your comments- comming from you, i know my engine is doing well!

Thanks again (everyone!)

Hi SP, I don't get into the oil wars but, I was wondering if the majority of the Delvac tests are close to these great results? Thanks and Later!

That is one of the best analyses I've seen here. The high TBN made it a dead giveaway that you're using Amsoil. I'll be doing an oil change on my car next weekend and Amsoil 10W-40 is what I intend to use now that I've seen your analysis.

Delvac is real good, but Amsoil is even BETTER!

Looks like a typically excellent Amsoil analysis. And just 7 ppm silicone after 10K...with a Piper Cross foam filter! That's also typical.

Keep doing what you're doing.

<font size="2" face="Verdana, Helvetica, sans-serif">They'd be the same numbers with Delvac 1, except that the TBN would be slightly lower. It starts out lower in the first place.

Mickey's right, gotta love that Amsoil and the PiperX foam filter!
