A while back I withstood humongous fury from several board members for my relating additive (namely VI Improver) stripping with the use of a 1 micron beta 200 filter in a real world application. And that it appeared to be VI improver stripping which the oil formulator of the oil shared can be as...

I have been asked for a description of the Pore Blockage method used in my used engine oil analysis: it is as follows: Particle Counting (BS3406) "The pore blockage method is a widely used method of obtaining an automatic particle count. In this method, a volume of fluid is passed through a mesh...

I had mentioned previously that my Toyota Sequoia's used engine oil was cleaner than the New Mobil 1R I put IN the engine. To be accurate, I submitted a sample from poured from a new Mobil 1R 0W-30 bottle and submitted it for particle count testing. New oil can be tested using laser procedure...

The comparative particle counts for my 2001 Toyota Sequoia with 159,000 total engine miles, using Mobil 1R0W-30 engine oil are as follows: OEM oil filter PC vs. Amsoil EaO57 Oil filter PC >4 Microns = 1,817 particles, 128 particles >6 microns = 990 particles, 70 particles >14 microns = 168...

The lab called today, Monday, 2/12/07 and indicated that they sourced two samples of Group IV PAO from two different sources and that the GC traces are very, very similar to the Mobil 1 EP GC that they ran originally. The only missing component is the comparative trace for a Group III, which is...

My second particle count is completed using the OEM filter, Mobil 1R 0W-30. Mileage this analysis is 1,574 miles. I will then install the Amsoil EaO filter and re-sample at 1,500 miles, then on to 10,000 miles for the long term comparative with my original particle count. First and Second PC's...

The floodgates of H*ll will be unleashed with this posting, but here is the latest on my GC sample processing. The lab called this morning, having run the GC on the Mobil 1 EP 5W-30. The results were inconclusive, which the lab knew may well happen, so they reserved samples of both Group III and...

As per my commitment, no news from the lab doing the GC on the M1 EP 5W-30... As of Monday, 1/22/07 George

Most recent Toyota Sequoia UOA, with particle counts. OEM paper oil filter. Amsoil EAO next analysis with PC. 10,000 miles on oil, 160,000 miles on engine/vehicle. Combination highway and very much off-highway. ISO Cleanliness 20/19/17 >4 microns 8407 Particles per ML >6 microns 4578 particles...

This will take a bit of time but just sent in my latest engine oil analysis to include particle count. This will establish a regular paper element baseline for particle counts, ISO cleanliness. Next oil analysis will be with Amsoil EaO filter element, with particle counts.. Should be...

Just as an informal poll, wondering how many folks are using/have tried acetone as a diesel fuel/gasoline additive. Acetone is getting much press as a signficant mileage extender for both diesel and gasoline. Just curious as to real world experience, mileage increases, side effects, etc. There...

Just curious but I cannot seem to find the 'results' of the in depth analysis; if they are buried in here it would be worth a whole new or standard top listing of the results... Thanks so much for pursuing 'the rest of the story' with this oil! George Morrison

Mobil announced today several new extended drain interval oils with performance guarantees.. Mobil Clean 5000 (5,000 mile ODI or 6 months), Mobil Clean 7500 (7,500 miles ODI or 6 months)and Mobil 1 Extended performance (15,000 mile ODI or 1 year, guaranteed).. However, for automobiles still...

I have had two oil changes with Mobil 1R on my Toyota Sequoia (twin overhead cam V-8) Analysis are as follows for Mobil 1 10W-30, Mobil 1R with 8,000 miles, Mobil 1R with 9,713 miles. Iron: 8, 9, 10 Chromium: 0, 0, 0 Lead: 5, 0, 2 Copper: 15, 7, 7 Tin: 5, 0, 1 Aluminum: 2, 2, 2 Nickel: 0, 1, 1...

Virgin sample of Torco 5W30 racing oil. Tin=30 (!) I have *never* seen this before in a new oil additive package! Al=4 Silicon=6 Boron=1 Sodium=25 Magnesium=15 Calcium=1944 Phosphorous=1773 Zinc=1341 Moly=2523 VI=185 Vis@40C=64.4 Vis@100C=12.0 One very unusual oil analysis!! George Morrison...

Fresh off the Press! The spectrographic oil analysis results for the Mobil 1R vs. current formulation Mobil 1.. Viscosity, 1R = 10.5 viscosity, 1 = 10.2 Calcium, 1R = 2856 3% greater than M1 Calcium, 1 = 2773 Phosphorous M1R = 1912 82% higher than M! Phosphorous M1 = 1049 Zinc M1R = 2105...

One of the most non common-sense procedures, yet *most* important for the proper performance of a water soluble metal working coolant is, simply, Oil In Last or OIL. Common sense says "put the quart of coolant concentrate in a 5 gallon pail first, then fill the pail up with water to get a better...

Does anyone know anything about this device? http://www.rentar.com/ It is termed a 'fuel catalyst' and that it can reduce diesel fuel consumption on the order of 15% to 20%! Sounds like snake oil BUT, one never knows! Would much appreciate any input on this device if anyone is familiar with its...

I had heard that the trucking industry's pleas may have put the October 2002 clean engine on hold or even cancelled? Reasons given were: 1. No one is buying the new EGR equipped trucks 2. As a result of 1., older trucks will continue to pollute thus negating the intent of the EPA 3. Total costs...
