That is not necessarily true. With a lesser oil that could be the case, but running a fully synthetic oil formulated to run at 100:1 at 80:1 should be no problem whatsoever. The lubricating properties of synthetic oils like Saber give you better lubrication and better motor life with less oil. Besides, like I said before, I have been running it at this ratio for a year plus now and I have had no problems.
