Prefer it in the gas over MMO simply because it seems to stay in suspension better. There is never any proof that anything like this works. The main difference that we notice is that the valves immediately quit making the typical small Continental clatter during idle when we use the additive and start doing it again when we stop. For me, its worth it just to eliminate the clanking sound. Several other cub owners in the neighborhood have noticed the difference in sound at idle and asked about it. Of course, that doesn't mean that there is any real difference in lubing, and the quieter engine may be just coincidence.

It does not meant it will burn ashless. It is used largely due to the fact that conventional piston aircraft engines have rings that do not seal as well as modern automotive engines, and this "ash:" contaminates the oil. To keep these contaminants from plugging small orifices, the dispersants in the oil keep these particles from clinging adhesively and cohesively. I have several aircraft engines running on automotive oil with no problems after three years. The solution is to seal the combustion chamber from the oil system. No ash= (No dispersant needed+ Less expensive oil+Less frequent oil changes)= Money saved. Will not go into details here for obvious reasons, but anyone who has partaken of my OSH seminars, knows it is not rocket science, just common sense. If automotive engines progressed at the same rate as general aviation piston engines, we would still be driving model "T"'s.

I am new to aircraft engines, but have worked on cars for years and specialized in electronic engine controls. When I saw a brand new aircraft engine with a carburetor and magnetos on it I about died laughing. When I saw the aircraft version of fuel injection, aka the mechanical fuel injection systems, I thought it was a joke! I keep wondering why aircrafts are so far behind? Then I remember cars of the early 80's with first version of electronic computer controls. In my opinion GM did two things in the 80's, first was to make the US think diesel engines were terrible, the second was to make the US think electronic engine controls were unreliable. That was 20 years ago and people still believe it, even though it is not reality! Think about the cars today with electronic engine controls, I know that I fully expect to get 100k miles from a new car with out a single engine related problem.

George Bass brought up a good subject about "Total Seal Rings." I called them, and at that time they requested that I send in my pistons so they could install the rings..........Maybe that procedure has changed........................CHEERS!!!!

Joe Moriarty, the owner of Total Seal, in Phoenix, is originally from my area, and had a shop here. Due to the varied nature of materials and uses, we have used his "second ring" on many of our applications. This is largely due to the fact that we use finely finished cylinder walls where no cross-hatching is visible. Our engines do not have time for break-in, and therefore must be prepared in such a manner that when they fire up, they are race ready, with full seating occurring in less than five minutes. Have applied this method to AC engines, and noticed a slight elevation in cyl temp, but by the time the ac was ready for departure, temp was down indicating rings had seated.

The best brands of automotive oil are still a fraction of the price of aviation. Remember, oil never wears out, it just becomes contaminated. Archie ________________________________ Message 14 ____________________________________ Time: 06:36:41 PM PST US From: "flyseaplane" Subject: Engines-List: Lead and exhaust valves --> Engines-List message posted by: "flyseaplane" Scott, go back and read that article. In the first paragraph, John Deakin states: "I do have one report that high-output marine engines had some valve problems when switched from mogas to unleaded fuels, but that same report said that hardened valve seats took care of that problem." He goes on to say: "Lead does NOT prevent (or cause) "valve recession." I disagree with that. I was there when "regular" gas disappeared, and I saw several vehicles without hardened seats start running like crap in no time - - - and ALL at the SAME time (running time wise). The only change was unleaded gas. Pull the heads, and the seats are all gone. So, my question is this - - - - - - If lead doesn't protect the valves and seats, why did the marine engines mentioned in Deakin's article have a problem with the valve seats once the lead was taken away?? My Lycoming O-290-D doesn't have hardened seats. I don't run straight auto gas, out of fear that the exhaust seats will diappear, just like in my pre-70's auto engines. If anyone comes up with a sure-fire way to fix the seat recession problem with unleaded gas, let me know!! Take care all. Linc ________________________________ Message 15 ____________________________________ Time: 06:52:54 PM PST US From: "Archie" Subject: Re: Engines-List: Lead and exhaust valves --> Engines-List message posted by: "Archie" Consider the engines running on Propane or Natural gas. Ever wonder what they use? I have repaired a few, and they have hard seats and guides. Some use a bronze alloy guide. A few use a stellite-faced valve. The ones I worked on were industrial applications. Do not recall the number of hours used.

I don't know for sure....) I think I could make the valves and seats in my Lycoming "unleaded friendly", but at what cost, especially since no one makes hardened seats for the O-290-D - - - Or for ANY Lycoming?? Linc ________________________________ Message 17 ____________________________________ Time: 07:14:04 PM PST US Subject: Re: Engines-List: Stump the Stars- RV-8 Engine Questions From: Kent Ashton --> Engines-List message posted by: Kent Ashton The usual problem is fuel, that is, not enough fuel flow, blocked fuel lines, etc. Be very careful to insure adequate fuel flow and run enough fuel through each tank to make sure no debris clogged the line. I just ran my Aerosport engine/dual lightspeed igns for a few minutes to check it and took off. The only problem I had was idle adjustment on the Ellison TBI. Took a few flights to get it adjusted As for the engine itself, I agree with Dick Rutan, who says the engine will always tell you before it stops working. I wouldn't worry a bit about the engine itself. Aerosport has a great reputation. --Kent > From: Don.Alexander@AstenJohnson.com > 6) Engine break-in- Aerosport will test-run the engine on a stand long > enough to make sure that everything is ok. ________________________________ Message 18 ____________________________________ Time: 07:14:04 PM PST US Subject: Re: Engines-List: Stump the Stars- RV-8 Engine Questions From: Kent Ashton --> Engines-List message posted by: Kent Ashton You ought to take a look at lightspeed Engineering's electronic ignitions (Klaus Savier) and Ellison Fluid Systems trottle body injectors (TBIs), really just a carburator.

I can't quote chapter & verse, but if memory serves, the connection between lead & valves wasn't lubrication, it had more to do with a 'cushioning' effect between the valve & seat. Does this jog anyone else's memory? (What's almost universally forgotten are all the sticking valve problems inherent in those old auto engines.) Charlie
