Oil Analysis Report

Old Chuck · 07-09-2009, 08:04 AM

To me, the real value is doing oil analysis over time. You start to see how your engine is holding up. Also, as stated, always get a TBN done if not standard. This shows how much of the additive package is left and in reality how long you can go on the oil. I have had good TBN numbrs at over 15,000 miles with Amsoil's best. Will be interesting to see the numbers on the 370 when folks start doing tests with some miles on them. Perhaps we will learn more about the effects of any high oil temps.

Yeah I've already gotten my first one back. I didn't analyze the factory fill unfortunately. At 1,800-ish miles I did an oil change using Nissan Ester 5W-30, then at about 4,000 I switched to Motul (300V, 5W30) and sent off that Nissan Ester out of my engine for analysis, this is the report from it:

I just changed oil against at 7K miles (to Motul 300V 5W30 again) and sent a sample off that off last week, haven't gotten the report back yet.

Ill be interested to see that. Im @ 500 and I think Im going to drop the factory fill in the next week or so. I dont think I will start UOA's until maybe 20k or so. Even at that mileage my last vehicles numbers were trending down.

Here is my oil analysis..

0-1500mi = Nissan factory oil
1500-5000mi = Nissan Ester Oil & Nissan OEM Filter

Wstar,

Do you think changing the factory fill at 1000 miles would be too late given the amount of wear metals floating around the oil? Should I have done it earlier?

You'll get 1000 different responses on that. It's probably not going to make a huge difference. Somewhere around 1500-2000-ish is probably decent, I got rid of mine around the 1800 mark. You do want to keep oil change intervals relatively short for at least the first 10K. I don't plan on going over 3K per change regardless of the TBN numbers for quite a while.

I figured everybody would have their own method to doing this.

Do you recommend that the factory oil be used until 3000 miles?

I have read a few threads, but the more advice, the better.

It depends on the oil analysis - once things start leveling out I'll go for longer change intervals. Coming from a Benz with a 15,000 mile recommended oil change interval, 3000 some miles seems laughably short unless it's being broken in.
