Changed oil at 760 miles...

[diverscale]

I looked through my oil filter element after my initial 10k miles oil change. There were visible wear metals visible to the naked eyes between the folds, the size of very, very small hair. I saw very few, also. Less than I though I would.

On the second change, did the same, saw nothing.

I too was going to change the new "break in" oil at about 1000.

I have always changed my new vehicles oil at around 1000 or so to get some fresh oil in there since most all initial wear and break-in is done in the first few hundred miles. But now I am conflicted.

I feel the 10k intervals are totally fine down the road after going 10k. But leaving the new oil for almost a year and 10,000 miles just seems so, wrong, to me. lol

I definitely don't want to undo some Toyota wizardry if the oil has special break in additives.

hummm. Interesting topic.

Ain't that the truth, and often it's knowing full well that I probably will sell said vehicle in a few years anyway. We can't help it.

BUT, I do plan on keeping the 4Runner a long time.

But then again, that's what they all say.

One of my positions was working for a large Transportation Company (largest in US). They have a fleet of over the road rigs and trailers. They were totally dialed in with Total Quality Management and did extensive research on oil, Synthetic and Dino and correct interval. Substantial data developed through oil analysis, engine wear and driving habits. All equipment was dialed into computer system monitoring run time, run speed, idle time and MPG.

What they found..........Synthetic is best. These where large truck diesels so needed minimum idle time after start and after a long run. Enough to cycle engine oil through the filter system removing any metal particles and most important acids that developed via the diesel compressed ignition process. At the time of my leaving, oil change intervals were at 50K per unit. This was monitored and happened religiously through extensive countywide maintenance network. It was common to have power units run normally without any engine issues at over a million miles.

Now to gas engines and our cars. We don't have the worry of acids in oil to extent a diesel engine has, but same principle applies. Start-up and minimum idle to start oil flow and full engine lubrication...about 1 minute. End of long run-idle for about a minute to have oil pass through filter. Then shut down. What kills our engines is the stop and go runs without engine getting to full operations temperature. Allows moisture to build up in engine and exhaust system. Today for example, left house at 7 Degrees and engine and vehicle didn't reach normal operating range for 20 minutes-15 miles of this on interstate.

I used to be a 5K oil changer fanatic. Now I take the time to ensure proper vehicle operations getting to normal operations temp and appropriate shut down. My T4R just rolled over 20K today and it does not use a drop of oil. My dad had two T4R's a 2nd gen and a 3rd Gen. He was brutal on them towing a bass boat all over the northeast with hard acceleration from stops. The 2nd Gen was a 4 cylinder and the 3rd Gen the 3.4 V6. Both ran flawlessly, the 2nd gen had 250K when he traded it for the 3rd gen. The 3rd gen had 160k and outlasted Dad. Only failure was electric antenna needed replacing.

To each there own in terms of comfort level with oil changing interval. Proven research has shown not necessary at low mileage intervals if you take appropriate operations steps.

My two cents

Interesting, but really hard to compare a long haul diesel with a daily driver SUV... I agree that a few principals may apply... but intervals ect are a totally different ball game. Overall oil capacity, is a big factor in change interval. Those big rigs carry about ~15 gallons :wow: of oil.

Driving style/use pattern is a big factor (number of heat cycles...). Most mfgs have a very proven algorithm now that takes all of this into account. It is so dialed in that GM had to have a campaign to convince service managers... that the onboard % oil life was the new standard to follow (most kept pushing the old generic intervals). However, Toyota does not seem to have figured it out yet (at least not for the 4R) ;-(

I shoot for 7k intervals on my 4 runner. Even though I wheel it on a regular basis in dusty conditions... I don't see how that makes any difference. I do clean the air cleaner way more often than recommended (about every oil change). Sometimes, I even swap in a paper element just for the super dusty conditions and then go back to an oiled element for the trip home.

your engine was built to some of the finest mass production standards the world has ever known. is it burning oil? does the oil smell burnt? is there EXCESSIVE shavings in the oil? all the above questions no? then no reason to ever worry otherwise.

hell, look at the 3.8L v6 that was in the 2007-2011 jeep wranglers. many of them burn a quart of oil between 3000 mile oil changes and are strong as an ox with a supercharger ontop of them. there was just someone who finally pulled their supercharged 3.8L out of their jeep with 225,000 miles on it to swap a V8 in; they cracked the block open and found no real evidence of any place where there was going to be failure, it just liked to burn oil.

Toyota (Dothan) had my first change at scheduled at 5000. At the new owners meeting they passed out coupons for a free oil change. I had it done at 1000. The service manager didn't see anything wrong with that. It was my preference.

I am sure the service manager wouldn't see anything wrong with them changing your oil every 1000 miles for the lifetime of the vehicle! More commission for them!
