I just saw a video of an engine running 7 min's without any oil in it at all, it changed my whole look about changing the oil.

I like Blotter Spot Tests as much as paper chromatography but in both cases I have no idea what I'm looking at. Kira

Quotes from MachineryLubrication may help:
Quote:
Chromatogram Patterns
In addition to the blotter codes, four different zones for each chromatogram were created (Table 2):

C - Center Zone - Area where the original oil drop was initially deposited
A - Aureole Zone - Rings formed outside of central zone
D - Diffusion Zone - Area of diffusion of medium to small size particles
T - Translucent Zone - End of the chromatogram (base oil and diesel fuels)

http://www.machinerylubrication.com/Read/498/blotter-spot-test

Quote:
A)Key Indicators for Soot:

Size of center spot
Color of center spot
Size of diffusion zone
Color of diffusion zone (black, gray)
Aureole formation (incorrect injection condition)
Density (translucent or opaque)


B) Key Indicators for Glycol

Size and color of center spot
Texture of center spot (sticky, pasty)
Size of blotter
Color of patterns (black, orange/yellow)
Aureole formation (glycol presence)
Density (translucent or opaque)

Blotter tests- poor man's UOA reports.

It is better then nothing and I have used it several times too.

What I do after 48 hrs is to take a picture and store these pictures for comparing the blots.

An uneducated guess says the dispersant is getting weak as the dirt is not carried out all the way to the outer edges.

This is a legit test but IIRC you follow the pics found on google to read the oil condition it has to be on white uncoated business card stock, napkin may spread the volitiles differently but I am not sure.

Yeh, I thought it looked a bit coarse. Published accounts of this method (apart from the original "business card" version) tend to be a bit coy about the medium, but some appear to be using fine filter paper, others specifically refer to Thin Layer Chromatography, which usually implies a silica coating on a glass or metal slide.

Coarser media probably won't show structure or debris fields as well. I've only tried fine filter paper (which of course I've lost) and printer paper, both of which looked a bit finer than your picture but still weren't very convincing.

Dunno. You don't have much structure and it isn't very dark, which is good as far as it goes, but I don't much like the peripheral line irregular edge, though that could be the medium.

I used to have a few links to reference pictures (which you've probably got anyway) but this is the only one I could now find from a quick look.

http://www.magna-guard.com/OneDrop.html

For WIW (not much) the one that looks most like your picture (to me) says "plan to change"

Anyway, to answer your question, of course you can. Who's going to stop you?

If you're going to continue to blotter test as an early warning of awfulness, you should perhaps try and get, and test, some finer media.

Other than $$$, I prefer Blotter Spot Tests to UOA in terms of ease and convenience, short lead times and most importantly it provides qualitative readings in:-
a) degree of loss of dispersancy(dispersancy zone);
b) degree of agglomeration of insolubles/soot/wear particles/polymerisations of base oils/additives etc (centre zone);
c) indicatons on absence/presence of glycol (darkened peripheral ring of centre zone) etc.

Yes, am keeping hard copies of Blotter tests samples .......

It may be a good idea to keep pictures as at 48 hours for consistency in comparison though.

Hmm...... agree with you dispersants should be getting weaker in use .....
but total absence of 'centre zone' in this sample suggests a 'weakened' oil dispersancy is still on top of the situations and more than adequate in dispersing remnant insolubles/soot/wear particles, I believe.
Though you may think/believe otherwise.

Note:the major/minor Outer Diameters of this Blotter Spot is 31 mm and 29 mm respectively.
