Are any of the readily available(Wal-Mart, etc.) conventional oils, that have consistently shown proven UOA's for a 5,000 mile OCI?
Is there a dino oil, that has shown proven 5000 mile UOA's

By "coventional" oils, does that include HDEOs or are you only defining that to include PCMOs?
PCMO's only
I went 4100+ using Chev Supreme 10/30 and still had a TBN of 4.2 and low solubles and wear numbers. No question I could have gone 5000-6000 with it.
But the only thing that matters is how far a dino will go in *your* engine, not mine or anyone elses. Try one of the better dinos for 4000, have it analyzed, then go 5000 or more if the numbers look good.

I'll second that.
I was just about to post this topic but Basser beat me to it. I was wondering myself if Chevron Dino 5W/30 would last 5000 miles if LC was used at an initial dose of 4 ounces and 1 ounce/1000 miles. This will be used in a 2005 Toyota Camry LE 4-Cyl. Is it safe to go 4000 miles after the 1st oil change at 1000 miles and then every 5,000 miles thereafter? Finally, should I just use Chevron Dino for that 4,000 mile run or should I use the mystery dealer dino, which is suppose to be Chevron 5W/30 (but I don't trust them). I am offered one free oil change from them.
Lastly, if I did an UOA at 10,000 miles after running Chevron Dino 5W/30 and LC for 5,000 miles, would it ruin my results if the dealer had used something other than the Chevron 5W/30 for the previous 4000 miles? I heard that the first use of any oil "cleans" up whatever is left behind from the previous oil. Any input is appreciated.
Thanks,
Michael

Please take no offense, but I think that you are over-analyzing. You have a great car and can reasonably expect to get a zillion miles of good service from it. My suggestion is that you accept the dealer's free oil change, and then use whatever oil makes you happy - you really cannot go "wrong". UOA is probably not necessary, but again, do what makes you happy.
I have a '97 Camry 4-Cyl (one of the sludge motors) that I have routinely changed the oil myself every 3 mo / 3000 miles with dino since new. That engine is hard on oil and, from that experience, I would not push dino oil past 5000 miles. However, I hear on this board that all of the new-generation Toyota engines (since 2003) have a better design are much easier on the oil - this is to your favor.
I am puzzled that you seem concerned about the oil brand and initial oil change intervals, when to do a UOA, etc, yet you want to use dino on 5000 mile OCI. Why not use synth oil? There are many benefits of synth over dino, and I think that you could easily exceed 5000 mi OCI. I switched my Camry to Mobil 1 5W-30 this past summer at 60K miles and observe that this oil is better suited for my hot-headed Camry.
Best Wishes as you motor along!

After I found out by a relative who works for the Mobil refinery in NJ that they have switched to Group III base oil for their GF4 Drive Clean 5w-30, I think I will go that route.
SWS stirred something up in my mind.
Does ambient temp affect temperature inside an engine? How do we know how oil performs at the MOMENT bearing surfaces are hottest, in August.
I may use M1 or Amsoil in summer for peace of mind.

I remember seeing 5000+ mile oil reports for
5w-20 Exxon Superflo
5w-30 Pennzoil
10w-30 Chevron Supreme
15w-40 Delo 400
In order to get a good report the engine has to be in good condition and there can be no coolant, fuel or dust/sand contamination.
Why buy Dino when you can get Motorcraft Synthetic Blend 5W-30 for $1.42 Qt?

Wouldn't doing a UOA cost more than simply changing the oil for only 5000 mile OCI's? Especially if you're using a cheap dino? (unless you want to know about the condition of your engine). You also need to do one every time the formulation of the oil changes to see how your engine handles it.
If you're going to do long OCI's, doing a UOA makes sense. But for short OCI's like 5000 miles, it makes more sense to me to put in something like M1 (just as readily available and only marginally more expensive) and go the 5000 miles with peace of mind knowing it's working.
Then do a UOA every year or two so you know how your engine is doing.
Just my $0.05 worth...

Gene K: Because Motorcraft synthetic blend uses only 50% so called synthetic(group III base) whereas Mobil Drive Clean dino is nearly 100% Group III base (the so-called synthetic). It just isn't advertised as a synthetic,(because Mobil only considers Group IV a synthetic), and it's $1.17/quart at Wal-Mart.

I believe it is grp II and Grp III in the motorcraft oils. The synthetic I don't know about. I have even read crazy stuff like GC being 80% esters and 20% GRP III. I have to take alot of salt with this forum and only trust a few posters so far to give hard facts rather than opinions.
Ugly3,
I have read that post several times and it is intriguing. I hope it's true but I am not 100% convinced. I am not questioning the veracity of those that claim it is, just that the information is so new I am giving it the test of time before accepting it as reality.
