Here's the post rinse phase UOA by Dyson Analysis. I'd say the difference is substantial. Looks like he still has fuel issues, but for 200k

The numbers seem weird, for a couple of reasons:

That oil in the 'later' run (199k) is older, SL-rated pennzoil, isn't it? The zinc and moly numbers seem to indicate it is....the 'earlier' run (195K) seems to be with SM Pennz, but the moly numbers are still really low......

Also, its weird how the 'earlier' run held its viscosity MUCH better than the 'later' run, even thouigh the 'later' run had less fuel, and a quart of 10W-30 as top-off....
 
Terry mentioned that the moly was off for a Pz product.

This is Dan's (fueltankerman) Escort.
 
So this is a sample of the rinse phase oil, or the oil fill after that?
I've never seen FP's so low, yet the fuel% is not that rediculous.
The AW additives do look high. Does Auto Rx have any of these in their formula?
The wear metals look great!
 
This is his rinse phase drain oil. I agree that this is one low FP without all that high a percentage of fuel. I can't begin to reason the this and that of aromatics ..but I ponder the thought that a certain percentage of fuel flashes off with sustained usage.

I think that this occurred in my 2.5 Jeep engine. I use a heat exchanger and reasoned that, although I had a low fp, the % wasn't as bad due too the oil reaching 200F+ on just about every event. Apparently 50% of your fuel components will flash off at these temps. Those that remain apparently require much higher temps (like 150C or something like that) to volatilize.

As far as AW in Auto-Rx, there should be nothing to show up on the UOA. Bruce confirmed that the ester constituents in Auto-Rx do have FM and AW properties.

The earlier OCI (with the AutoRX in it) was Advance Auto 10W40 oil, which is made by XOM I hear.

This rinse phase is 5W30 bulk Pennzoil sold at Walmart, in their lube shop. The weather was really rainy here and I had a lot to do that weekend, so I did not change my own oil, I just took the car to Walmart and had them change the oil and I watched as they got a sample. I have had Walmart do the last two oil changes on this car, and both times they used the bulk 5W30 Pennzoil.

I don't know if the bulk Pennzoil is exactly the same formula that you get off the shelf in the bottles.

As I've mentioned elsewhere, the AutoRX treatment has made a HUGE difference in this car. It's not just "seat of the pants" either, I'm getting better fuel mileage (around 7% better on average) and the power is up considerably--well beyond enough to know that it's not just in my mind. The car just runs a lot better than I remember it running in a long, long time.

It probably does need some injector help. I ran some Techron through the tank about 10,000 miles back. But the car is literally worth less than the total cost of parts for new injectors, so I'll probably just keep running it like it is until it breaks. :)

They have bulk Pennzoil at Wal-Mart? I thought they used Valvoline products at their lube center but if you wanted you could pay extra to use off-the-shelf stuff? Maybe it's different in other locations...
 
what ever it was, that bulk dealer was clawing to make a profit on it. Bulk oil sales are extremely competitive as it is. It would surprise me if the sale was actually at a loss just to bump some threshold of volume.

You can get reconditioned injectors from Linder Technical Services for about $25 each. Dunno if that's still too much. I've used them before, they work great.
 
Thanks, Brian, that's worth considering. :)

And Gary, that guy says he's going to do the compression test before and after on that 1989 Ford Ranger V6 with 340,000+ miles on it. That's the one with Valvoline 10W40 all the way, and never a rebuild. He says it's starting to really lose power, and is getting only about 14 mpg now, down from around 19. I gave him a bottle of ARX and he'll do a compression test first, then dump in the ARX and run the truck 1500 miles and change the oil, and retest the compression. I'll do a post on that whenever the data gets here. He might even spring for his own UOA on this one, especially if the truck runs a lot better after the treatment, which I assured him that it would. :)

Yes, tell him to leave it in longer. 1500 works ..but no sense in wasting oil when it can be left in longer. The old way worked just fine (1500) ..but getting the green light for longer usage just makes sense if you can hang.
