Blackstone oil report

I am sure that when the oil change is finished, you have not used 100%. You will probably still have enough new oil from the 6 or 7 quart bottles left over that you can also place in a new sample bottle and label it as such. You can put the batch date and number on the label. Then when you do the oil change, you send the "clean" oil with the used oil. And now you have your control.

Being a Comm'l H.V.A.C. tech for the last 25 yrs, and an Auto Mechanic just prior to that, hasn't helped me one bit wrt the idea of neglecting my obligatory responsibility of changing my truck's oil every 2500 miles.
Now, I just bought my 2nd 4Runner on April 21'st of this yr; my 1'st was a '98 SR5. It now has 2,500 miles on the clock. I always believed that, on a New Engine, you needed to change the oil @ 1,000 miles; during break-in due to the excessive metallic particles in the oil.
And truthfully, I'm a little concerned about not changing the oil...like tomorrow!
Is it really ok to wait until the truck reaches 10,000 miles before dropping the oil?; that's unthinkable. Getting Nervous :wow:
rigtec, Cheers

Wow, you only have 2500 miles? I bought mine on April 21st too and I have 18,000 miles already.

Do you feel comfortable changing the oil at the recommended interval; 10,000 miles???

No, for now I am doing at 5000 miles. I am of the opinion that oil is cheaper than replacing an engine.
Before I switched to synthetic about 10 years ago, I had changed oil every 2000 miles for a couple decades. But about 12 years ago I changed carriers and now have a job that requires up to 1000 miles per week of driving my own vehicle ( I get reimbursed for gas and have some compensation for miles driven) but I found myself changing oil every other weekend. So I switched to long life synthetic oil and extended my interval to 5000 miles at that time.
Since then I have put well over 200,000 miles on two different Grand Cherokees without any engine problems. So I believe that 5000 miles is a perfectly safe change interval for modern engines.
I am reluctant to push it to 10,000 that is why I sent the sample in for testing. If they say it would be fine, then I might do it, but have not really made up my mind yet.

I am an inspector and service technician of certain equipment used in hospitals and surgery centers. I have to go to where the days work is located, sometimes it is nearby, but usually it is not.

I was only goofing around! As an A/C service tech, I'll do about 150 to 200 miles per day on service calls, so I completely understand; but I don't use my 4Runner for that.
Thanks for your input Vic, still trying to wrap my head around why friction related composites, eg...copper, aluminum, teflon, steel (to say nothing of exhaust gas by-products), do not impose adverse effects on the oil, and ultimately..."The Engine".
Thanks for stepping in, your insight is greatly appreciated! Greg, aka rigtec
2000 Mile Oil Change Results
Since the 4Runner was new I decided to change the oil at 2000 miles and will change again at 5000 miles. The first 5000 miles will be where most of the wear occurs. After the 5000 mile oil change I will change again at 10,000 and see how it looks.
As you can see from the Blackstone Lab report it shows a lot of wear metal as to be expected. Which is the main reason I changed it at 2000 miles.

This whole engine oil analysis stuff is a complete waste of time and $.

And scientific analysis beats bro-science any time.

Blackstone and the folks at Bob is the Oil Guy have a lot of documentation on this. It tells you a great deal about how your oil, your engine, and and your fuel interact.
For instance:
1. If silicon is detected in the oil, you probably have either a vacuum leak somewhere or your air filter isn't seated right. You'll see higher levels of wear in other metals too, since silicon particles are abrasive.
Result: You realize there is an issue with a loose vacuum hose or your filters before it can increase long-term wear in your engine.
2. If a lot of sulphur is detected, you might be running fuel with enough impurities in it to overwhelm the protection package in the oil you're using. Since compounds of sulphur tend to be corrosive, you'll either want to evaluate a different fuel or shorten the OCI. LPG and CNG engines get this, as do some types of diesel engines. Some gasolines also have higher sulphur content.
Result: longer engine life
3. The total base number is lower than expected. You're either running the oil in question too long, too hot, or you have blowby that's causing fuel to accumulate in the oil, thinning it.
Result: Now you can talk about perhaps switching to a thicker oil.

Very good! Also it will show trace amounts of water or antifreeze if you are having problems.
Think harder.

Hurr, durr, herp, derp.
Nope, can't think like a bro, even typing that was hard. Even one over 21, whose idea of class is a golf shirt, baseball cap, and a sport coat. And I'd get a rash if I actually tried using bro-grammar and bro-spelling. I'd rather be tased, quite frankly.

I actually don't like your silicon count, at all. It's possible that the OEM oil had some sort of silicate compound in it, or some dissolved sealant, but if your next change throws that number I'd be undertaking a really intensive audit of your vacuum hoses and post-air-filter intake.
