James, I’ve been reading your oil/energy columns. Very informative, thank you. It seems I am getting some less than adequate answers to my question posed to my local motorcycle dealers. I have two motorcycle’s (both about 45-50 mpg). Buying ‘motorcycle 20W-50 oil’ or “Harley Davidson [brand] 20W-50″ motorcycle oil is more expensive versus just 20W-50 oil. If you have time, is all 20W-50 the same or should I pay the extra at the motorcycle shop since motorcycle engines run at higher rpm’s and the oil does need to have whatever makes them more resistant to the heat and stresses associated …

Sir: Just a note on long term fuel storage. I have discovered that fuel both diesel and gasoline stored in 33 gallon plastic drums with the bungs tight has lasted in excess of five years without a stabilizer. The food grade blue drums have white gaskets in the bungs that have swollen slightly but have not deteriorated. The plastic drums were stored inside 55 gallon steel drums and shaded from direct sunlight. My observations are that the plastic drum expands and contracts (collapses) with the fuel. My assumption is that, with no air breathing, the problems of water condensation, evaporation, …

James, Very interesting discussion of storing motor oil and other lubricants here! Here is the burning question that perhaps yourself or the throngs of Survivalblog readers could answer. Does detergent or synthetic motor oil degrade over time to be less effective than non detergent motor oil or does it just degrade enough that it might not meet the original American Petroleum Institute (API) rating? It sounds like detergent and synthetic motor oils may only degrade compared to the original API rating and not actually become less effective than non-detergent oils. If someone plans on driving an Audi 1.8T post-TEOTWAWKI then …
