hi I haven't seen any one forcing kingtech owners to use kingtech oil or voiding warranty. but if the tech guy's are seeing
bearing damage through different oils it's a bit of a no brainer. I don't really care if the kingtech oil is not suitable for other
turbines as I imported the oil for my kingtech customers only. I also carry mobil oil for any one else that wishes to use it.
price wise in oz I can sell kingtech oil ($14.00 lt) cheaper than mobil oil any where around $20.00 per lt depending on where
you source it. that's my two cents worth
