Dale Posted March 16, 2011 Author Report Posted March 16, 2011 The claim that AvBlend can't be used for turbocharged airplanes is completey FALSE. First, AvBlend states that it can be used for turbocharged engines. If you have information otherwise, please post it here; otherwise I would refrain from posting information which appears to be erroneous. Second, check the AvBlend website, it also clearly states that it can be used for turbocharged engines. Third, check with some reputable engine shops. The mechanics that are familiar with AvBlend will tell you it can be used for turbocharged engines. Fourth, check the testing that was done on this product, a lot of it was done in turbocharged engines. Fifth, I don't know if I would want to make inaccurate statements about a product, since everyone is trying to decide what works and what to use in their aircraft engines. Stating that a product can't be used for turbocharged engines when all the information available indicates otherwise, seems imprudent unless you intend to post information supporting this position. I also don't think the manufacturer would like it either if they read such a post. Quote
carusoam Posted March 16, 2011 Report Posted March 16, 2011 So I took Dales advice....and went to www.avblend.com AVblend did receive an FAA letter: FAA approval for use in airplane engines: http://avblend.com/images/faa/faa.pdf From AVblend's FAQ section... "Is AVBLEND ok to use in turbo-charged engines? Yes. AVBLEND works very effectively in high temperature environments persistent in turbo-charged engines. " The fine folks at avblend made a demonstration to the FAA using a WGN helicopter engine - "Enstrom Helicopters, powered by Lycoming HIO 360 C1A" Generally speaking impressive long runs on cylinders with minimal wear. FAA demonstrations / measurements were made at 1,000hrs and 1,100hrs of operation. Seems very early on in the overall 7,000+ hours put on their cylinders... Now I can understand where people draw the line. AVblends statements: FAA Approved for use in airplane engines, and OK for use in high temperature environments persistent in turbo charged engines. AVblend does not come out and hit the nail on the head... They do not say it is OK to use the oil additive in turbocharged engines or in oil related to the turbocharger itself. Nowhere does it say "approved for turbocharged engines" Are the turbos in mooney's oil cooled from the engine oil sump? Do mooney turbos get hotter than turbos on other planes? It is difficult to compare the results of helicopter engines that get used everyday to an airplane engine that sits 9 out of 10 days. You can see I am not protecting my airplane from over use. I keep using Aeroshell 15 - 50. Unfortunately, I just don't see a good way of demonstrating one oil additive package over the other. Best regards, -a- Quote
DaV8or Posted March 17, 2011 Report Posted March 17, 2011 It all comes down to, who's hype, propaganda, or "facts" make you sleep better at night. If the FAA says it won't wreck your engine and it gives you relief knowing your engine isn't rusting to death as you breath, then go for it! Quote
jetdriven Posted March 19, 2011 Report Posted March 19, 2011 You got me. I did some heavy research a few weeks ago about Avblend and Camguard, and CAMGUARD is not approved for use in turbocharged engines. Sorry for the misquote. Quote
danb35 Posted March 20, 2011 Report Posted March 20, 2011 ...and the lack of approval for Camguard is somewhat puzzling given that turbocharged engines were used in the test program for that product. Quote
