A year ago, I realized that the these engines always produced great UOAs, so I decided to continue my 7500 ODI on M1 10W30 and quit doing UOAs until I hit 75K miles or so. Well a full year has passed, and I accidentally went over my ODI by 1500 miles... 9K miles on the oil, so I decided what the he!! , let's see what the oil looks like...???

Was there ever any doubt? These engines just keep pumping out great UOA reports.

I'm thinking of upping my ODI to a nice round 10,000 miles, and performing my next UOA in another 12 months.

Anyone object to my plan?

Let me be the first to give a genuine yet corny

CLAP! CLAP! CLAP!

Very nice! Continue whatever it was you were doing!
 
I have been running 15,000 oci's on a TLC's I6. (694,000 miles) From all indications, the V8 is even more "bullet proof" and easier on th oil than even the I6.
 
Interesting. One would almost think that this oil has been only a relatively short period of time. I say that bc of the low (600 ppm) for the phos/zinc.

chinee,

What kind of oil filter are you using? I remember reading a previous post of yours and it seems as if you were using a Purolator Pure One. Are you still using it? I am changing the oil on my Sequoia with M1 at 5K intervals. Obviously, this is overkill. I will stretch that to 7500 miles now. I'm at 89,000 miles so it's time for the timing belt to be changed. I haven't decided if I'll be doing it myself or not.

I think it is more then likely additive depletion! Remeber how my M1R looked like regular M1 after 6 months in my Toyota! A year is a long time for an oil not designed for long drain use to last!

As is the norm now the Toyota V8's and newer V6's seem to be the jewels instead of the I4's of yester year! I will say that the newer I4's are not slouchs though!

What I find really impresive is that these Toyota V8's in the trucks are by Toyota standards cheap unrefined Lexus based knock off's! Buy cheap simply mean that they do not have sodium filed valves, titanium rods,simpler valve train, are cast iron block ect.......By truck standards they are the most refined well poished engines on the market! I can not wait for the larger more powerful V8 and diesels to appear!! I think it is more like a $15K-$20K engine in a $25-$35K truck!

The rear axle assembly is also about as tough as you are going to get on a 1/2 ton! I do nto know if the third member rear ends Toyota uss are Ford or Chrysler knock offs put they seldom fail!

One thing I have noticed over the years is that Toyota was smart about copying the best design features from the big three early on. When they found something that worked they stuck with it unless the customer demanded something different or something better came along! If they can borrow something from in house as is they will if they need to scale it up or down they will! You do not see them waste money trying to reinvent the wheel!

I also saw early on that as a young man when they needed a top notch fuel injection system they went right to Bosch and saved a fourtune on R&D up front. Eventualy they liscensed the design I am sure and based their future systems on what they learned from Bosch!

It makes you wounder how ever turn a profit puting mostly great engine designs on the market with occasional lemon or sludge beast!

Yep... still using the Pure One, and leaving it on for the entire interval. It seems to be working just fine, so as someone wiser than me has said, "... if it ain't broke..."
 
Maybe a little clarification is warranted...

It'seen a year since my last UOA, but not since my last oil change. The oil was in use for four and a half months.

ruking,

I assume TLC is the Land Cruiser... and do you have 694,000 miles on the original engine? Or has it been rebuilt a few times? What year?

No matter how good these engines are, let me remind that these trucks are living happy lives in balmy CA and FLA.

Bring them for 1 winter OCI over here and do a UOA after. Might not be as great.
 
The oil has thickened by about 15%-20% in 9000 miles, which is normal for a big V-8 engine with a small sump.

I don't see any issue with running 10,000 miles, but I would switch to the new, Mobil 1, extended life filter. The "SAE HS806" filter test results I"ve seen would indicate that the PUR-1 oil filters don't have much dirt holding capacity.

I think the total solids level may be lower with the better filter.

Nice results. You got your money out of that M1. If you can get results like this at 9K OCIs.....synthetics make a lot of sense.

How many quarts does the 4.7L hold?

at least your not using mobil 1 EP at 5k intervals

6.5 quarts... and it does not consume much of it during the interval, I drained a litle less than 6qts out.
