I think this kind of a response is uncalled for. But besides that, if you didn't want any opinions or factual information then why did you (or whoever it was) ask the question in the first place?? If you want to believe that your snake oil makes your plane go super fast go ahead and believe it. I don't think any reasonable person cares. Just don't put someone down who was just trying to present some factual information that contradicts your claims. The CAFE foundation did do a lot of good and came up with quite a bit of very useful information about aircraft efficiency that hadn't been documented before and probably put to rest some unfounded rumors in the process.

One more thing to keep in mind: Fully synthetic engine oil (like the Mobil-one that was mentioned) does NOT like leaded fuel. So run on mogas or use semi-synthetic oil at best. These are the options that you have. FWIW.

A full synthetic oil will not absorb or keep in suspension the lead deposits that build up in an aircraft engine operating on leaded fuel. The lead just settles out and cannot be removed by changing the oil like it can in an AD or semisynthetic oil.

Werner" Subject: Re: Engines-List: RE: OIL --> Engines-List message posted by: "Konrad L. Werner" For what its worth: I talked to a Racer at Reno '03 about the oil(s) he used in his Engine. His answer was "Redline Synthetic" for racing only, and Aeroshell while flying enroute to Reno and going back home, ...and any other year round flying. He said that Redline Racing Oil gave him a little extra oomph when competing, but that it would not handle 100LL well at all. How much oomph exactly, I don't know. It probably was not much, but then milliseconds count in racing and can mean life or death for being # 1. Some sacrifices need to be made to get closer to the competitive edge. That's why he uses of the shelf aviation oil in his engine when not racing (which is most of the time), as it does its intended job best. While I have extensively used Mobil-1 in all my gasoline engined cars over the years, I would certainly not use it in an aircooled aircraft engine burning 100LL. There are better oils out there made just for that specific environment.

His answer was "Redline Synthetic" for racing only, and Aeroshell while flying enroute to Reno and going back home, ...and any other year round flying. He said that Redline Racing Oil gave him a little extra oomph when competing, but that it would not handle 100LL well at all. How much oomph exactly, I don't know. It probably was not much, but then milliseconds count in racing and can mean life or death for being # 1. Some sacrifices need to be made to get closer to the competitive edge. That's why he uses of the shelf aviation oil in his engine when not racing (which is most of the time), as it does its intended job best. While I have extensively used Mobil-1 in all my gasoline engined cars over the years, I would certainly not use it in an aircooled aircraft engine burning 100LL.

One more thing to keep in mind: Fully synthetic engine oil (like the Mobil-one that was mentioned) does NOT like leaded fuel. So run on mogas or use semi-synthetic oil at best.

It looks like I really hit a bandstand nerve, as some were quick to whip out their HP 41C's. Nice touch, Spock, with the two decimal place correction. Well I have to admit that I can't argue with the fundamental cubic relationship between power and air speed. James, I checked out the CAFE site, but there is nothing there about the effects of various oils on air speed or engine power. There is a nice one on the effects of a wax job though. My first response was to add to the Cummins diesel experience posted by Larry Martin. I was only passing along a related experience, that of a professional drag racing team which found that using Mobil One could shave a few hundredths of a second from their quarter mile times. On the basis of that information, another EZ pilot I know tried Mobile One in his EZ and found lower engine temperatures and noticeable speed increase. He claimed a 5 knot increase. Now we could probably expect that he rounded off to the nearest 5 knots. Perhaps he even exaggerated a bit, I don't know. This was not a scientific test and that was never the point. The point was that he noticed an improvement in both air speed and oil temperatures. How much is debatable. Now if you are suggesting that he imagined the whole thing based on your calculations then I'll make a note of that. J. Healy ----- Original Message ----- From: "James R.

Not that its not a good oil, but I personally prefer Aeroshell over Exxon Elite in Aircraft engines. However, I do prefer Exxon's Mobil-1 Synthetic over any other "S-x" rated oils in my gas guzzlers. Second choice is Castrol GTX mineral oil which I have used in my gasoline engined cars as well. I am on my third Dodge/Cummins Diesel, which run on either Shell Rotella or Chevron Delo 400. To ask which Oil is the best is truly a "slippery" subject to answer. It depends on to many variables to come up with one simple answer. do not archive P.S.

Werner" Subject: Re: Engines-List: RE: OIL --> Engines-List message posted by: "Konrad L. Werner" Dear Scott, A comparison like that has been done by Aviation Consumer (I believe?) a couple of years ago. If I recall correctly Aeroshell tested better than Exxon (which Exxon then questioned, of course). Exxon in turn tested better than Phillips (which Exxon & Phillips did not question). Castrol Aviator was not even around yet, I think? Keep in mind that these were laboratory tests to mimic the real worlds need for wear-, tear- & corrosion protection. Each of these oils are good oils, while some may be slightly better. Remember, the best thing to do to any engine is fly it often and regularly, regardless of oil brand. A hangar queen with the best oil is worst off than the daily flown hauler run on any of the other oils. And change the dark soup regularly to get rid of the junk accumulated. P.S.: Is there anyone out there that could offer us ~2000hrs in his/her Twin to run Brand-X in #1, and Brand-Y in # 2 exclusively, so we would have a more direct comparison? Now, if we had a Tri-Motor then we could also run Brand-Z at the same time as well as do not archive. A quad engine test may really be to much to ask, I think! ----- Original Message ----- From: Scott Bilinski To: engines-list@matronics.com Sent: Monday, May 09, 2005 12:31 PM Subject: RE: Engines-List: RE: OIL --> Engines-List message posted by: Scott Bilinski I can understand being a fan of XXXXXX oil, but based on what?

LOL back to you. I just not a fan of long dissertations. Sorta like asking what time it is and being told how to build a watch. The dangers of using leaded gas with synthetic oil is news to me. Nice to know, I guess. I've been using synthetic oil for years and I'm sure at times with leaded gas. I don't recall having any oil related problems, in fact just to opposit.. Do not archive.
