We could do what GA does even for homebuilt Experimental aircraft. That is maintenence in accordance with CASA Schedule 5.Schedule 5 is well known to LAME's and easy enough to comply with. Look at the Maintenance Guide for Engineers, by cASA and it will be explained.

As far as checking the oil in Jab engines, their method only works in Jab airframes. If I fill my taildragger to the full mark, a large proportion of the oil will end up under the belly.

yen . that grey stuff on the pistons is lead!. av gas here is loaded with it. this will also play havoc with your valve guides then valves. most jab owners i know don't use it, use 98ron and a little flash lube to protect valve seats in cars we use about 500 ml for 5000 kms . to much will cause soot build up under rings and may cause them to jam in grooves dmech
