Toyota,Subaru BMW, VW, I know for a fact do not use special break in oil. Not sure about American cars. As far as I know Honda is the only one still using this special oil. I always follow what the master techs say for our extreme environment out here. With the manufacture I listed above none of them said there was anything wrong with changing oil at early for the first oil change. I was told brake in oil is a thing of the past like over 20+years. I have always followed dealer recommendation.
You should NEVER put oil into your brake hydraulic system!

Or put you brake in oil. Is actually typing the correct word really that hard??
Thatās the mistake that most people make with K&N and other oiled filters. They clean them way too often and then over oil them. The truth of the matter is that even under severe conditions. You should only clean the filter maybe every 25k miles or so. K&N themselves suggest a 50k mile cleaning intervals. I highly doubt that youāll need to clean it 2 or 3 times a year.
The main reason you donāt see much in the way of N/A FA20 builds is because, youāre not addressing the FA20ās major failing by trying to get to it stay together at 9000 RPM. That engineās most obvious problem is a lack of low and mid-range torque. Something that a small twin-scroll turbo can easily rectify.
Apparently it is .
In the 1960s/70s there were 2 or 3 service stations that sold 115/130 octane leaded avgas. You could also purchase 105 octane leaded gasoline at major brand stations.
Starting in the early 20s it wasnāt till the mid 73 when catalytic converter came in to production and forged internals came about that they stopped using tetraethyllead or tel in gas. This was used primarily as an octane booster and would coat older car internals and valves with a thin layer of lead, it also would cause spark plugs to fail early. It also raised the compression of the engines making them run cleaner. In 1996 they banned all tel in USA and Canada. Only a couple countryās still have avgas with tel.
100 Low lead avgas still contains lead. I live in an Air Park. If I had a gas can I could walk 1 1/2 blocks to the Fixed Base Operator (FBO) and have it filled with blue tinted 100LL I would not pour it into my catalytic converter equipped car thereby voiding my warranty. This is current information from Shell Global.
Summary of Avgas grades
Avgas 100
The standard high octane fuel for aviation piston engines. It has a high lead content and is dyed green. There are two major specifications for Avgas 100. The ASTM D 910 and UK DEF STAN 91-90. These two specifications are essentially the same but differ over antioxidant content, oxidation stability requirements and max lead content.
Avgas 100LL
This grade is the low lead version of Avgas 100. Low lead is a relative term. There is still up to 0.56 grams/litre of lead in Avgas 100LL. This grade is listed in the same specifications as Avgas 100, namely ASTM D 910 and UK DEF STAN 91-90.
Avgas 100LL is dyed blue.
Effective January 1, 1996, the Clean Air Act banned the sale of the small amount of leaded fuel that was still available in some parts of the country for use in on-road vehicles. EPA said fuel containing lead may continue to be sold for off-road uses, including aircraft, racing cars, farm equipment, and marine engines.
Aircraft that use avgas should only be prop or spark plug run aircraft like small air craft and some military right?? As far as I know all jet and turbine plains use lead free gas. Iām not sure what the military uses in its jet and turbine powered aircraft.
Thatās cool that you live in an air park. Is it really loud or do you get use to it?
Turbine/turbojet/turbofan engines generally use jet fuel (JP-8) which is more or less kerosene. Diesel engines can run on it.

Cool. So avgas is used vary little just for small aircraft ?
piston engined aircraft. use avgas.
Itās a small state airport in a small city. The residents are very considerate with noise abatement. With 30 years Army National Guard all aviation with the final 20 years also full time Department of Defense civil service at the same flight facility and now over 16 years at the air park I am used to it. FoDaddy gave you an accurate description of jet fuel.
