lead a little on the high side? what is the trend like?

hannaco · Oct 7, 2003

Lead about doubble from the prior three samples. Amsoil was used prior to the Exxon Super Flow.

Brons2 · Oct 7, 2003

if you really want to use a dino, a lot of folks seem to like chevron supreme. it's 1.09 a quart at walmart.

otherwise, i saw your amsoil uoa, it looks a lot better.

hannaco · Oct 7, 2003

I switched to Super Flow to do an Auto-Rx treatment. Once motor is clean, will go back to synthetic oils.

jason07-1zzfe · Oct 9, 2003

So this had AutoRX in it or was this the rinse? If either, that is most likely reason for higher lead number.

It's $1.08 up here. Dude, you're gettin' hosed!!

You guys really think he needs to go back to $6/QT oil when he's getting good results from a $1.29/Qt oil?

The engine's got 85K miles on it. Statistically speaking, 16 ppm (while twice what he got on Amsoil) is noise. Bearing wear is not what will doom that Astro, not at the rate of 16 ppm/ 5000 miles.

Hannaco should save the difference to replace all the stuff that will start falling off the van in the near future.

Considering the monster wear these shorty 350's put out this isn't so bad...

I wonder why these "shorty 350s" are putting out more wear than my actual 350 though?

sbc350gearhead · Oct 9, 2003

4.3's are not very well balanced, which is why they use balancing shafts on the new ones. Even with the shafts, they are not very well balanced, but they are very very durable, and I know several with well over 200k and still going strong. One example I know of, has 250k, and doesn't use a drop of oil in a 5k OCI. I find that to be quite impressive.

Cutehumor · Oct 12, 2003

is it just me or is everyone that posted a uoa of exxon superflo has some kind coolant leak, high silicon that raises wear metals or an engine that typically has high wear numbers.

I'm on my first batch of superflo 10w30. by second batch, will post uoa.
on my maxlife UOA, I had a 14 ppm lead 3k interval.

Yeah, my 4.3 does not have a balance-shaft, and you can definitely feel it thumpin' around.

Sudden though...with the high wear numbers the 4.3L puts down, I wonder how it lasts so long? Hmmmm...

cutehumor as you point out the Superflow is niether consistent or great at reduceing wear. To date the few UOA have all had high OXidation,nitration and insolubles. THe lead numbers have also been high. I kind of lump this oil into the same catagory as Mobil Drive CLean. They are best left on the shelf for someone else to buy!!

JoggingGuy · Oct 19, 2003

I was wondering if this oil was worth anything. I saw a whole lot on sale at Walmart last night for .84 a quart

Isn't superflow and drive clean, the same oil?
