WACO, Texas (KWTX) - With crude oil back above $90 a barrel, drivers may feel the impact beyond the gas pump - including at the oil-change shop.

One local lube shop says his costs are up 40% since April, prompting a price increase and late-night trips to stores to keep oil in stock.

Craig Barker, owner of Master Lube in Waco, said the cost of motor oil, especially synthetic and synthetic blends, has climbed sharply.
