Shortly after I switched to full synthetic Honda oil at 8,000 miles, the oil level sight glass now leaks a little. It's not spilled oil dripping down the case from the fill hole. It is definitely coming from between the glass and case. I've heard in the olden days, synthetic oil could make oil leaks more likely. Is that true of modern synthetic oils? Was this just a coincidence? Has anybody else's sight glass seal started to weep?
