I pulled all my research and wrote the internet payback machine to have the archives pulled as well. I did the research for my own engine program, and quite frankly I was dumb enough to post it online for a while.
Charles at LN and I discovered Brad penn and brought it to the air-cooled world at the beginning of the millennium. I swore by it for many years, but then it changed, and now the company was sold and it has changed again. Don't get too comfortable in your choices, because they are constantly changing, whether you know it or not. I first noticed that Brad penn changed when it lost a certain smell out the tailpipe of a few of my cars. I approached the VP of marketing and he admitted to it. That pissed me off, because we were assisting them and they didn't even bother to tell us. Oil threads are funny, guys that don't even know how to properly read a used oil analysis are swearing that what they use is the best when they don't even know what a TAN or TBN value is. Thats why I gave up posting anything and stay fairly quiet on the whole thing. All I know is that since 2001 I have lost ONE engine due to a cam and lifter failure, and that was my own. I run the oils we have developed with Gibbs in everything from my lawnmower to my Deutz tractor, to my AM General 5 ton military truck to my 512 TR Testarossa and the 308, not to mention every VW and Porsche I own. Thats a fleet of 30 vehicles and each of them is a rolling test bed for some flavor of engine oil. I have reams of UOA evaluations that are 3" thick and we pull samples from every car that we drain oil from, customer or otherwise, on top of every engine that we build. If we drain oil out of anything, we collect a sample. I am VERY biased because my benefit from working my ass off to collect data is that we have the ability to know exactly what changes in a formulation, and sometimes thats just the type of moly or polymer thats used. I develop oil to make our engines have a chance at life, because in 200-2001 I lost 30 engines due to using the 'old standby" oil that we'd used for years. Luckily all of them but 3 failed on the dyno and lucky we figured out why and attacked the issue before anyone else in the industry had figured it out. All that said, there's only one study remaining and its not even valid today because the oil that was used has also changed, and has done so several times since the study was conducted. Its a 160,000 mile bit or empirical data that will give you a sample of what we've learned. This is of course, from a T4 engine. http://www.aircooledtechnology.com/index.p...ileage-teardown Before you say that I am just trying to sell oil, understand that I won't sell you oil if you beg me to. In fact I have no way to sell anything except a turn key engine since I sold my store in 2013. We are developers. I don't give a shit what sells. |
