I just bought one a bout three weeks ago, so I'd be interested too. I have 700 miles on mine. It's a 6 speed.

AFAIK, there is no break-in oil but there is a break-in filter factory installed. Change it at the first oil change, too.
Okay, so what's so different about the break-in filter?

According to the manual, I should shift at around 1500-1800 rpms, which brings the engine down to 800-1,000 rpms when upshifting in the lower gears. So far, I"ve only touched 3,000 rpms once. I'm rarely above 2500.

In sixth gear, I'm doing 2,000 rpms at 60 mph. So 90 would be only 3,000.

Besides P/N (90915-2004 from factory, 90915-YZZD3 from dealer), the media type, amount and construction is different. There are cutaway analysis online, last I saw was on SpyderChat, though they tend to lose their database every so often.

There are no RPM limitations listed in the manual for break-in. Yours listed are "Recommended" shift points for "Cruise" type shifting, the lowest RPM's listed. "Acceleration" type shifts are of course higher RPM as you prolly saw.

Correct about 90 mph with the M/T and 3.9 diff in an FJ, guess it's the same in the Tacoma. The manual also lists 109 mph as "Maximum Allowable Speed", but I don't think any police officer would accept the owner's manual as an excuse.

When I had mine, I kept it below 3000 RPM's for the first 500 miles (make sure you do not tow anything) and then after 1000 miles I took it to redline. Also, I took delivery on mine with 250 miles on it and it was driven from Ohio to Michigan via dealer trader so I know it was driven 75 mph + those first 250 miles.

I never had a problem with the engine and I was heavy on the pedal too. Smoothest drivetrain I have ever had in a vehicle, the Tacoma felt like a FWD car (shifting that is) + idle was perfect!

Congrats on your purchase.

Yea - the factory oil filter is a far superior construct than the replacement D3 you get from the dealer. I read an article about it somewhere where they broke down the details and disected the factory filter versus the replacements - amazing difference. I've heard of folks getting those factory filters shipped over here from Japan, but it's probably easier just to get a high quality aftermarket oil filter like Wix, K&N or Mobil1. Not that the D3 is bad, it's just not top of the line.
