Does anyone have experience with "Avblend"?

I have some engine vibration issues and my mechanic thinks it might help.

He also mentioned adding Marvel Mystery Oil to the fuel?

Hi Stan, I've been wondering about Avblend also, have researched it on the internet and of course there are lots of nay sayers but as usual none of them have used it. It is FAA approved and they have records to prove their data to get FAA approval and that sounds good, I'm thinking I'll try some at my next oil change. I have used MMO in my gas for a nunber of years and it does help with plug lead fowling and valve & ring sticking in the Cont.
I hope their is someone with real world experience with the Avblend that posts.
 
Here's a quote from the person who formulated CamGuard. This was on the Piper Owner Society's website:

"Re: Marvel Mystery Oil vs. Avblend

We analyzed and tested both of these additives at Exxon.

Marvel Mystery oil is 30% varsol (charcoal lighter fluid) and 70% 30wt base oil some red dye and wintergreen fragrance. It is from the late 1920s.

Avblend is very light weight paraffinic base oil (sewing machine oil)with 1% ether and blue dye. It is from the late 1950s. If it is absorbed by the metal, why doesn't it leak out of the can?

These are solvent type products. Some people find them beneficial for sticky valves or some sludge dispersal. If you are depending on them for either of these reasons, you have bigger problems.

Both evaporate within hours in an engine. Neither one provides any corrosion protection or anti-wear benefit. Neither one will harm anything in the recommended concentration.

Well its another nay sayer who claims to have knowledge but is totally unabashed at providing a link to what he is selling. I find that more than suspicious and he lost credibility with his statement why doesn't it leak out of the can if it soaks into the metal and another of his statements it evaporates out in 20 minutes same old story that been tossed out for the last 70+ years.
Now if this is any better I don't know but here is something to read also

Again I have searched the web and I just don't know I find engine shops that say use it I find places that say its great and just as many that say it nothing more than snake oil. I can't find one of the articles I read just a week ago that I found convincing enough to consider giving the product a try. I'll keep looking.
Ok heres what I first read but didn't realize at first it was from the Avblend site

It is interesting the article in the southern-aviator, that a real simple test to try and when it warms up I;m going to try it after all I already have the wifes muffin pan in the hangar, I will have to fins a place for the nuts & bolts in it :D
 
Avblend vs. Marvel is an apple vs. orange debate. They do different things

Avblends main benefit is its ability to "stick" to the cam and other internals that ride outside of the normal oil splash/slosh zones. They claim it helps prevent dry-starts, which it might, but it does tend to cling to parts a little longer; that's good if the airplane goes for extended periods without use or you live in a moist environment. But flying your airplane and hanging upside down every once and a while can do the same thing.

Marvel is great because of its detergents. They help scavenge carbon deposits and absorb the extra unburned TEL (lead) out of the cylinders (which might help them run a little smoother!). Marvel really shines in the older engines; radials, small continentals etc... but can still help keep a modern engine up-to-snuff. Lighter fluid or not, it sure does help.

On the small Continentals, i have always used MMO - it is similar to Redex which used to be sold be the shot at gas stations as 'Upper Cylinder Lubricant'.

It does clean things and helps with the sticky valve problem.

Personally, my own answer is regular oil changes - 10 hours/4 months on an A-65, 25hrs/4mths on everything else. If you do that, you will save the cost of the Avblend and achieve a similar result................... Oh, and don't baby your engine, give it some beans on a regular basis, it will last a lot, lot longer :wink:
