Used a synthetic oil filter with non synthetic oil. Any problems?

"Some of our vehicles are designed to take advantage of the properties offered by synthetic oils," Marsaud says. "On other vehicles, the use of synthetic oil will not hurt your engine, but it is unlikely to increase performance or extend the life of the engine if the proper maintenance is done." ▪️Nissan recommends Nissan oil filters, regardless of the type of oil you're using.▪️ "While we can't comment on other manufacturer's filter designs, Nissan filters are designed to properly filter the microscopic particles from engine oil whether it is synthetic or traditional motor oil," says Didier Marsaud, Nissan Canada's senior manager of corporate communications, in an e-mail. What matters when replacing a filter? How well the filter does its job – get one with a filtration rate that's the same, or better, than the filter your car came with, Mott says. "You want 20-40 microns or smaller," Mott says. Certain filters (all of Nissan's, the company says) have added features – like an anti-drainback valve that holds the oil in the filter after the engine has been shut down. "It allows oil to more quickly reach the top of the engine on startup." Marsaud says. "Not all filters are alike."
