Oil additive survey

Mike S · #1 06-13-2011, 04:09 PM

O.K., VAF brain trust, my engine seems to be pretty well broken in, so I guess it is time to think about using an additive with my next oil change.

But, the cost is

If I use the recommended two cans of Lycoming additive, it will cost more per change than the oil itself

What is the consensus here???

Thanks in advance.

I use Camguard. Even if their claims are not valid (hopefully not the case), it is a small price. Currently I am using Aeroshell 100W.

Using Aeroshell 15W-50 which has the lycoming pack in it.....allegedly

I am using Aeroshell 100W Plus which has the additive in it.

I have been using Marvel since the first hour. I add 4 ounces every oil change. (25 hour oil changes, 50 hour filter change). Also add 8 ounces in each tank every other fill up.

Does it work? Don't know but it makes me feel better. Never had an injector problem and my Blackstone Labs oil analysis reports show a oil trends normally seen in engines with hundreds less hours.

Oil is Philips XC.

MMO for me too! Oil during the change, and 8 oz in the fuel.

i guess mmo should of been a choice in the poll judging by the comments. been using it in the oil and fuel for a long time. i did vote for avblend because i have used it before mmo in the rv and use it in the r-44 now.

one thing i do know is that the old atomic four gas engine that was in my old sailboat needed mmo to keep the valves from sticking. that stuff really works and the price is right. fuel and oil additive. i have some bonanza owners here who fly a lot and use mmo religiously. thats my 2 cents. first engine went 3,150 hrs on that stuff.

First of all, wanted to say I use MMO in my fuel as well.... but am curious as to why MMO would be used as as an "anti-scuff" agent (whatever that means) in the oil rather than the additive in A/S 15-50 or Exxon Elite or Avblend. I believe MMO is basically a super lightweight oil with a detergent in it (stoddard or equivalent) to keep things clean in the engine, and help remove deposits when used in the fuel. If something were to be added as an "anti-scuff" agent in the oil, wouldn't something like STP Oil treatment be better as it's thick as honey? I also notice lots of folks using the Phillips XC oil with no additive in their lycomings.. does it not really matter that much?

Using Aeroshell 100W and voted None.

But, will start using Camguard on my next oil change due to the article I read yesterday(Sport Aviation) promoting the benefits of Camguard vs the others.

Update: Went to my FBO today to buy a quart CamGuard... $59.95/pint. Checked ACS $24.25/pint, a little better but YIKES!!!

One can of Avblend will do. (or maybe it is 2 with the 6 cylinder engines)

I've been using the Avblend for years. What the heck, like the MMO guys, you've got to believe in something.

Years ago, while having an O360 overhauled at Blue Print in Chicago, I had a tour of Avblend's shop which shared the same building. I came away a believer. Their product penetrates metal surfaces like nothing else and provides cold, dry start protection. At least that's the line which the FAA bought and consequently issued approval of it in aircraft engines. In fact, Blue Print offered a warrantee of 500 hours and 3 years if I used the stuff which was quite a bit better than Lycoming's warrantee at the time.

Does it work? I don't know. All I can say, my engines have run well without any internal issues.

Like many products marketed without much science to back up claims, positive testimonials are used and there are plenty of them on all this stuff. No question, people are having success using it.

Sort of like buying health supplements - some of it really does work.
