I posted on here years ago when I bought a case of Aeroshell's then new Sport Plus 2 aviation two-stroke oil. It was developed with Rotax for use in ultralight and light aircraft with 2-cylce engines. I used it in all my 2 stroke equipment for years. My Lawnboy mowers smoked at 32:1, so I settled on 40:1 and that's what everything got. Can't really give any good info on it as I never tore down or did any inspection of anything, but I can say I saw no problems associated with using it.
I bought the oil 8 years ago and I have a few quarts of it left.
DO YOU THINK ITS STILL OK TO USE THIS OIL?
I last mixed up a batch of fuel with this oil at the beginning of spring and I used it and it seemed fine.
I don't know how to read the production code, but the best I can decipher, it may have been made 10 years ago in 2009!
It still LOOKED the same a few months ago as it did the first time I used it 8 years ago, and it is all from the same case.
The bottles have a foil seal on the bottle, under the lid.
I got on a canned Small Engine Fuel kick (SEF, VP SEF) both straight and premix a few years ago, so I only used the Aeroshell rarely for a few years, so the bottle of Aeroshell I used this spring was opened at least a year prior. It seemed to be good when I poured it and when it was being used in equipment, but, how do you know?
Should I use this oil? And if not can someone explain to me how oil goes bad inside a HDPE bottle with a foil seal? Go easy, I am an amateur.
