Meant to post this a few weeks ago. Pretty cheap oil from Costco, got good reviews from independent guys online so I figured I'd give it a shot. Came back way better than I expected. I'll be running this in my rig from now on!

Shame on for not using OEM Toyota oil.

Kirkland oil is GF-5. An obsolete grade. Toyota recommends GF-6A.

(I’m kidding. They are practically the same.)

The cheaper you go - the shorter your T4R life. Nothing to be proud off.

Same lab, Tahari factory filled oil.

Not unusual to see high wear metals in the factory fill, as well as visible metal particles on the first oil filter. That's why I do a 1k mile change. Probably unnecessary, but cheap peace of mind.

Okay. Oil related question. When I did mt first oil change in 1976, I was instructed by my Dad to warm up the engine first. So I took the car for a short drive, and then of course I scalded myself when I removed the drain pan plug and the hot oil started to pour out. In those days it was necessary to warm up the oil because it was straight 30 weight oil and if cold would take a long time to drain.

And I have stuck with that regimen ever since. A month ago I did the first oil change on my 4Runner. The first vehicle I’ve owned that used 0W-20 oil. When cold, that stuff pours like pancake syrup. I bet it takes more time going for that warm-up drive than it saves in oil-draining time. So with such thin oil, why bother warming up the engine before an oil change?

Thoughts?

One good reason is to homogenize the oil “mixture”. Helping to suspend everything that is in there within the oil so that it drains out with the oil rather than remaining “stuck” to the oil pan, walls, etc…

^This!
There's a lot of crap in the oil that settles out after you turn off the engine and let it cool. If you drain the oil when cold all that crap is still sitting in the bottom of your oil pan. General recommendations are to at least let the engine warm up. Myself, I only change the oil after the vehicle has been driven for at least several miles and the oil is hot and all that crap is suspended in the oil so it can all drain out.

You guys are probably right.

Yep.

Former master tech at toyota and independent shops. I've seen the crap that gets left behind when motor oil is drained cold, even overnight. I always drain the oil out of my own vehicles when the oil is still at full operating temp after the engine has run long enough to achieve that.

Hot then. I’ll consider the matter settled. As a former master tech, what is your opinion of the Fumoto drain valve, or similar?

As long as the threaded portion of the valve doesn't extend up into the pan preventing the pan from draining completely, and the valve doesn't leak, I think they're ok. I prefer a regular drain plug, magnetic if available.

Toyota ^^^ OEM oil user, no doubt.

IVe been using Redline 5w30. Seems nice and smooth, better for the heat. Marginally less fuel economy but with MTs what does it matter. The 0w20 is just CAFE bullshit for fuel mileage. Lots of other places run 30 weights in these motors.
