Mobil1 0W-40 • 5,991mi • 2019 4Runner 33k

[ScottyB]

cut down the interval a bit on this run due to a lot more towing than usual for us - 1700 miles over 4 days pulling a small camper, fully loaded, with the engine locked out of overdrive. Toyota recommends a 5,000 mi OCI for severe use, I figured I wouldn't stray too far from there. lots of mixed driving in between and a ~500mi beach roadtrip thrown in too. the 1GR seemed to shrug it off just fine.

OEM Toyota oil filter was used in conjunction. the M1 seems to be a great fit, I don't plan on changing anything other than adjusting OCI slightly based on severity of use.

Looks good! 6,000 looks like a good oci.

Was 0w-20 originally specified?

Great report.

 

[wpod]

The M1 didn't break a sweat.

Wow 6.0 TBN on a Uoa. I thought that was around where it starts when it is poured out of the bottle? Or am I delusional? Lol.

I do hear m1 0w40 does have some of the best add packs.

yep 20 is spec'd in the US, but the manual states running a thicker viscosity if the vehicle falls under severe use (hot weather, long idling, cargo carrying, towing, offroad use, etc) along with a shorter OCI of 5k vs. 10k. everywhere else in the world this engine will call for up to a 20W-50.

Whatever M1 has done to their new formulas, it's definitely working. I read the uoa section here religiously, and M1 is currently getting the lowest wear metals.

Scotty - thanks for posting this UOA.

My lack of towing experience will now become evident: why lock out the O/D?

So the trans doesn't hunt between the top gears plus it keeps the rpms higher and in the power.

what wpod said - the 4Runner is relatively low on horsepower and gear ratios to begin with, so it would be hunting between 4th and 5th constantly with the added load. the locking and unlocking of the converter in overdrive would add quite a bit of thermal strain as well which is why its generally common practice to keep a vehicle out of its highest gears when towing and just let the converter stay locked in a lower gear even if the engine has to turn a bit more RPM.

Technically 5w30 is the original spec, as that's what Toyota called for when the 1GR first came out. The move to 0w20 was purely for fuel economy reasons.

how do you lock the engine out of overdrive? Are you pushing the 'sport' button, or are you switching to "Sequential" mode by putting the shifter over to S. Do you then have to manually shift? I don't see an O/D button on my 21 rav, does your new 4 runner still have the o/d button?

M1 0W40 is not your average ILSAC M1. It is for European vehicles requiring full SAPS oils and is approved for toughest approvals like MB229.5, Porsche A40.
Starting TBN is 12.9, HTHS 3.6. Porsche is using it on 24hrs circuits.

in our 4runner, we can drop the shifter over a notch into "S" just like you said. that automatically defaults the transmission controller into "S4" which is limiting the transmission from shifting past 4th gear to its highest gear, 5th ( although you can still select any gear, including 5th). in S4, it will still drive like an automatic, just that it will hold that gear limit you put on it. i should note in the 4Runner, S4 is meant specifically for towing because the trans will still lock the torque converter (this cuts down on trans fluid heat and provides more efficiency), but in the lower 3 gears it will not.

i tow or do around-town driving (under 50mph) in S4 all the time to keep the trans from gear-hunting, and sometimes i'll put it in "S2" when i'm in bumper to bumper traffic so i can keep the trans from constantly trying to upshift and take advantage of some second gear engine braking.

in the 4runner with our old-school transmission, its not particularly good at - or meant for - shifting manually gear-by-gear like a manual transmission, but rather just as a way of selecting the highest gear it should shift to automatically. your Rav4 might be different but i doubt it.

no O/D button like the old days - "D" is overdrive and moving over to "S" mode takes you out of it.

Yes sir. CAFE

I saw with qsud, copper at 22. That's high wear!
Mobil...alk that calcium! 2237! That's the most calcium in any oil?

copper is always high on these when the engine is still factory fresh and breaking in, its not really a wear marker to worry about. QSUD did fine but i thought the TBN was dissapointing.

Maybe. It has enormous additive pack.
