'07 Toyota Tundra, 5.7L V8, Amsoil 0W-20, 4,960 mi

Truck is a 2007 Toyota Tundra 5.7L V-8 CrewMax, driven mostly rural (55 MPH) highway, but with some city and idling with the A/C running hauling the family around on weekends. Averages about 19 to 20 MPG, so you can tell I don't really drive it hard. No oil additives and I've been going back and forth between Lucas UCL and SuperTech TCW3 at about 600:1 as a fuel additive.

I'm still under warranty, hence the under 5K run. Sure, AMSOIL ASM 0W-20 is overkill here, but only recently has anyone started carrying 5W-20 around here and the only 0W-20 is a sporadic offering of Mobil1 at Wal-Mart at more than what I was paying for AMSOIL even with shipping. And I usually leave Wal-Mart in a bad mood because of something - long checkout lines, bad children, rude people, blah blah blah. When the Amsoil is gone, I've got 12 quarts of SynPower (O'Really rebate steal) and then probably am going to use Motorcraft semi-syn after that.

My thoughts on this UOA are summed up in one word: BORING!!! And I like boring.

The only nit I can pick is that it seems viscosity is up on this run versus past runs. (All except the 2.6kmile change were 0W-20 ASM.) And even here I'd wonder if the difference is explained by the measurement error.



thanks,

Vis starts at 9.0

Hey Pablo,

Thanks for the reminder - I should have checked my vis spreadsheet. Maybe less shearing on this run, then?

Very nice example of everything trending down with break-in, especially Si and Cu. Nothing to complain about, everything very good. I agree - boring in the best possible way.

Your UOA is assuring to me as i run the same oil in my 07 tundra. I think it's a great oil, but mine don't look to good with only 6k miles on the oil. I have also replaced the OEM filter twice and 1 qt makeup oil added. I use the truck mainly for towing heavy trailers, so we'll see how it compares to your UOA. I may switch to the wix filter next change, as they don't offer an EAO yet. Wix claims it to be 96% efficient at 15 microns, whereas the OEM is a 30 micron filter, so i've been told.

Any comments?

P.S. UOA coming soon.

Why didn't you run it out to at least 7500 miles this time with the previous UOAs to back it up? I would do 10k miles now.

Because warranty requires oil changes @5K or six months.

How do you like the Tundra pulling heavy trailers? I've seen mixed reviews and would love to hear what you think. I've never towed more than 3 or 4k behind mine, and honestly, couldn't tell I had a trailer behind me at all!!!

When you say "don't look to good" at 6k, are you referring to visual appearance of the oil? I'll admit, mine is a pretty dark brown at 5k, but as seen in my UOA, it could have gone far longer.

I'm looking forward to your UOA, as many people who don't like 0W-20 oils like to point out that they may be okay for light driving, but won't have the thickness needed for towing. I don't agree and I won't hesitate to put a 10k load behind mine filled with 0W-20 and tow from here to the end of the earth.

I've been using Toyota filters - they fit and seem to work well for me. As to microns, there are several ways to rate micron filtration. If Wix and the OEM use two different methods, you could get very different numbers, yet in practice filter equally well.

I'm looking forward to an EAO for this truck too. Although, it seems per my UOA that the Toyota filter works fine for me...

thanks!

Warranty issues. I'd rather spend more in oil/filters and be in total compliance than school Toyota's Warranty folks on the interpretation of UOA's.

But for sure, with this truck needing 8 quarts of oil, I'm fully broken of my old 3k OCI habits! (although I still do the 'stang at 3k, as that's about once a year)

Great UOA ..indeed boring (yawn). Warranties are pesky things. They make most advantages of UOA and great oils pushed out for years.

You could of course at least double this oci safely. One thing you could do to save some labor is run that hard to change canister filter every 10k miles and drain the oil every 5k. No ones going to give you any warranty heartburn with that hybrid approach.

Noticed you're in HSV, Al - so what sort or rocket scientist (solids/liquids), R U???

I agree great UOA. Is that 19-20 mpg accurate? I've been getting 20+ mpg with my 4.7, also driving 60 mph. To get that mpg with the bigger engine is impressive, and it's barely broken in yet. It might even improve a little more.

Now that's an idea. The worst part of the 5.7L Toyota oil change is the awful cartridge filter. To get at it, you've got to drop a skid plate. What a pain. I may try this next UOA - change the oil but leave the filter on. Insoluables would tell the tale.

I used to be a rocket scientist, but not anymore and not at Marshall. I worked at Johnson, doing first shuttle then station stuff. I left in 2001 when it was clear to me that another accident was not an "if" but a "when", plus Houston was too big for me. Unfortunately, I was proven right with Columbia. To this day, I can't watch video of it without a lot of emotion. I had worked with each member of that crew minus Ilan Ramon.

Yep, it's accurate. Maybe even a little low, as when I've checked the mileage against what the computer says, the computer reports about 0.3 to 0.5 MPG low. The 19-20 is what I see on the computer.

The 5.7L Tundra has one advantage over the 4.7L fuel mileage wise - the 5.7L has a six speed transmission behind it. That helps a lot - it turns maybe 1100 RPM at 55 MPH?

This Tundra gets about the same mileage as my '95 Ranger with a 4.0L 5-speed. I can't get over that...

I am very impressed with the trucks power. I pull a 7500lb 5th wheel with it and it does a fine job. I drive a little faster than most while towing, but the truck still yields 9-11 mpg. And that's here in Utah with lots of hills to pull. I also tow a 5th wheel alluminum horse trailer with 4 horses (9k lbs+) and the truck pulls it better than my 5er. Wind resistance is the reason.

Yes, i'm referring to the color of the oil which was almost black when i took a sample last week. Lost 2 qts cause i couldn't get the plug in fast enough, it was a little hot. Your UOA is reassuring that's for sure. But the driving conditions will dictate my outcome i beleive. I'm hoping my UOA comes back as nice as yours, but i simply don't know. I have my doubts.

You have a point on the filters. I've been using oem as well, and i've been pointing the finger at the filter. Maybe i shouldn't be?
It seems to be doing the job for you.

I don't think i'd leave that old filter in that long myself. I've seen too many after a change to beleive it's a good idea. But i'm no expert that's for sure.
I don't have to drop the skid plate on mine, i cut a 4" round hole in the plate and do it that way. It's plenty thick metal.

O.P.

My UOA didn't come back as good as yours. Take a look.

Are you running an oilable filter as well? Your silicon is the same as mine.

Nope. Stock paper filter. Heading over to check out your UOA now.

I just found out that ASM oil comes in virgin form with 5-7 ppm of silicon anyway. So an 11 isn't so bad after all.

Oh, You may want to check to make sure the bands around your intake are tight. There's 2 of them. One at the box and one under the engine cover. Mine were lose when i checked and i beleive possibly this could be some of the reason for the high silicon.

I can't beleive you're running a paper filter. I would think they'd do a better job of filtration than my TRD. Interesting..

Good suggestion on the clamps - I'll check them today at lunchtime. My wife loves the truck so much I've got to share it with her, so today was my day to take it.

Yep, paper filter - still the one that came with the truck. Maybe it's time for me to change it with a Wix or maybe the TRD filter. For sure, your silicon with the TRD filter isn't high at all!

In my opinion, 10 to 15 PPM silicon isn't much worrying about, especially with some in the oil to begin with.

thanks much,
