Looks like anyone in a climate that never sees less than 10* F can run 15-40 Anyone try this yet? Seems a bit much but who knows?
I have. I noticed the engine ran much quieter but I also noticed my milage dropped by 1.5 mpg.

The robust 4.0 engine will be fine with either oil under normal operating conditions and ambient temperatures across the USA. For most operating conditions above normal, 0W-20 is adequate and at the same time less capable to protect than a higher viscosity oil.
In city driving, my wife tends to make short trips and tries to pass everyone on the road. When the vehicle warranty expired, I began using 5W-30 for driving from Phoenix to Flagstaff, moderate load, grades up to 6%, high ambient temperatures and speeds of 85+. An OBDLink MX+ shows coolant temperature rises 5 degrees and ATF temperature peaks at 224 F on the steepest grade.
I change oil at 5000 miles and filter at 10,000. So, taken all together, I appreciate the extra level of protection 5W-30 offers.
ever change your ATF or coolant? if yes what did you use?

I am blown away with how clean the 4Runner’s oil is after 5000 miles. It seriously looks new.
On the contrary, my 2012 Range Rover is a prime example of a high mileage, direct injected vehicle that turns the oil pitch black in less than 500 miles. The manual has the audacity to spec an oil change interval of 15,000 miles. Not kilometers.

here's a report on Mobil1 oW-40 that i ran for just over 7,000 miles. we fall into the severe category in climate and use, so its a good fit. seems to love this oil going off of the extremely low wear metals. flashpoint is an anomaly because of the way Blackstone calculates it; my guess is its actually totally normal. might shoot for 8k miles next time depending on how things work out.
we see a combined average MPG around 18.5 for mixed daily driving and it runs smooth and quiet. i'm not actually a huge M1 fanboy, but their 0W-40 is excellent as a cheap, tough, easy to find 40 weight that's not too far on the thick side. i've been running it in my other vehicles for years now.

Thats a fantastic report, nice to see the 4R eat that 0w40 with ease.
Running Fram's ultra synthetic filter also, I'll report back on what I think about it. Seems to flow better but that could be my wishful thinking.
There is a thread by Antman in the mods, writeups sticky that has all you need to know about changing oil including part #s of filter etc. Basically OW20 synthetic and OEM filter cartridge is recommended. Filter cartridges and the housing removal tool are available on Amazon. Interval is in the owners manual . Some members are using a shorter interval if they drive in harsh conditions.
Also, some members report broken skid plate bolts when oil change was done by the dealer. Solution is to remove plate ahead of time and using anti-seize on the bolts before installing. I'm using Mobile1 OW20 FWIW.

This is my current setup, getting 18.6 MPG (Hand Calculated) mixed driving. No interstate just Florida Hwy and city driving.
10W30 in the 4.0 V-6 engine is the incorrect viscosity, or are you talking about another engine?
The Dual VVT-i 1GR-FE in the 5th gen 4Runner, is speced for up to 20w50 in some markets. The 0w20 spec here is for CAFE reasons.
Ie: He can use 10w30, but his MPG will be very slightly worse.
He might also have less wear in the engine due to the better HTHS and MOFT characteristics of the higher viscosity oil.
I think I got the same OBDLink devise to monitor all my fluids; just curious how you got your screen setup? I really like the piece of mind I get from being able to monitor all my fluids on the trail or long interstate driving.
I have the OBDLink MX+ and I like it. Display data is similar to yours as well as some diagnostic data, such as catalytic converter temps, all cylinder misfire count, diagnostic trouble code count, short term fuel trims, long term fuel trims, knock data and tire pressures. YouTube videos explain how to diagnose rich or lean conditions using fuel trims and oxygen sensor voltages. I hope I'll never have to dig that deep into a diagnosis, however it's there if I ever need it.
