If i have a question re any thing I own I contact the manufacturer direct if possible much more reliable in respect to a specific piece of equipment than you will get from this forum. I have read so much misinformation here and on other forum I take the advice given here with a grain of salt. Anyone can claim to be an expert or some military expert or better yet a self made electronics expert. LOL All one has to do is review any best oil topic to see all the expert and their claimed expertise on the subject.
