well i add methanol regularly (Heet type stuff)... that should clean them out right?

 

Bluegrass, if you are using the manufacturers recommended oil change interval, the blends will turn in the lowest wear metals, averagely. The PAO synthetics will generally have the highest wear metals and dinos will be in the middle. To put this in perspective, a blend may have an iron level of 10, in the same engine the PAO may have an iron level of 16, and the dino will weigh in around the 12 mark. Same engine, same driver, same miles driven. So on paper, it would appear that you will get more miles out of the engine by using a blend. Not necessarily so. The level is in PPMs (parts per million). If you figure that into percentages, there is little difference. We see much lower iron levels for cold winter usage with the blends and dinos than the PAOs. That's primarily due to surface corrosion that the PAOs allow that the others do not allow. The blends are the best of both worlds. Considering Fords new spec on the oils that qualify for usage in a Triton, the newer blends are close to being bulletproof. Look for the 929 and 930 spec on the bottle. If it has it, it is one tough oil and it usually is not at a premium price. But if extended oil changes are what you are looking for, the PAO's are the only way to go, for now.

In regards to how an oil is formulated and how the manufacturers come up with their specs would require a book. And there are numerous books written on it. You would need to be a chemical engineer to understand just the process, not to mention the chemistry.

 

Methanol will keep water out of your gas, but won't touch the varnish in your injectors. Most bottles you see on the shelf don't do much and are a waste of money. There are only a hand full that are effective. Neutra and Fuel power will for a fact disolve that varnish. Seafoam, Techron, and Amsoil PI do well.

 

so you are saying that using the motorcraft 5-20 is better then the stuff i am using anyway?

 

Just an FYI:

I work for a company that manufactures particle counters -- which are often used in hydraulics and fluid power for oil analysis. I've found that Noria.com is an excellent source for information on oil analysis. It even has a message board where people discuss the results of various oil analysis results/mechanisms. Lots of the discussion focuses on industrial applications and complicated spectroscopies. However, there is still quite a bit of discussion on mobile applications, including personal vehicles.

People there are absolute experts on oil analysis. I don't mean to denegrate anyone's knowledge here. I just wanted to point the original poster to a forum with a much narrower scope and focus.

Good luck.

 

Labnerd , thanks for your information.
I consider this some of the most important information needed by the public, that usually cannot be found.
.
I have one more question if you might want to comment.
Nitration: If oxygen bearing additives are introduced into the gas, that release extra oxygen during combustion, would this add to the results and not be helpful over the long term.
As I understand it, alcohols in nearly any form will tend to do this.
I run a Ford powered sprinter on 100% meth, but we change the oil once every week at the track between runs. I would feel we have little problem with oil for this use except upper cylinder wear rate are a bit higher, but these engines are not meant for long life between rebuilds like a street unit..

Thanks again.
